&gt; A null value will remove the specified attribute

So it looks like you want `.attr(&#39;disabled&#39;, null)`.

I hope I haven&#39;t missed anything obvious in the doco, if I have I&#39;m sure someone will help.

I&#39;m using asp.net webapi to return a DTO, with date fields. These are serialized using JSON.Net (in format &#39;2013-03-11T12:37:38.693&#39;). 

I&#39;d like to use a filter but in an INPUT element, is this possible or should I create a new filter or directive to accomplish this?


    // this just displays the text value
    &lt;input ui-datetime type=&quot;text&quot; data-ng-model=&quot;entity.date&quot; /&gt; 
    // this doesn&#39;t work at all
    &lt;input ui-datetime type=&quot;text&quot; data-ng-model=&quot;{{entity.date|date:&#39;dd/MM/yyyy HH:mm:ss a&#39;}}&quot; /&gt; 
    // this works fine
    {{entity.date|date:&#39;dd/MM/yyyy HH:mm:ss a&#39;}}

Is there any shortcut I&#39;m missing?

I want an SQL statement to get the row with a minimum value. 


Consider this table:

    id  game   point
    1    x      5
    1    z      4
    2    y      6
    3    x      2
    3    y      5
    3    z      8

How do I select the ids that have the minimum value in the `point` column, grouped by game?  Like the following:

    id  game   point    
    1    z      4
    2    y      5
    3    x      2

Can I in D3.JS remove an attribute? I&#39;ve added it using `.attr(&quot;disabled&quot;, &quot;disabled&quot;)` and now I am looking for something similar to jQuery&#39;s `.removeAttr(&quot;disabled&quot;, &quot;disabled&quot;);` to remove it again. Useful for `&lt;button&gt;` and `&lt;option&gt;`. I&#39;ve tried using the `.remove()` but that removes the entire object not the attribute.

I have an object that may be extended along my behavior under test, but I want to make sure that the original properties are still there.

    var example = {&#39;foo&#39;:&#39;bar&#39;, &#39;bar&#39;:&#39;baz&#39;}
   
    var result = extendingPipeline(example)
    // {&#39;foo&#39;:&#39;bar&#39;, &#39;bar&#39;:&#39;baz&#39;, &#39;extension&#39;: Function}

    expect(result).toEqual(example) //fails miserably

I&#39;d like to have a matcher that would pass in this case, along the lines of:

    expect(result).toInclude(example)

I know that I can write a custom matcher, but it seems to me that this is such a common problem that a solution should be out there already. Where should I look for it?

I am using RequireJS and need to initialize something on DOM ready. Now, RequireJS provides the [`domReady` plugin][1], but we already have jQuery&#39;s `$(document).ready()`, which is available to me since I have required jQuery.

So I have got two options:

 1. Use the `domReady` plugin:

        require([&#39;domReady&#39;], function (domReady) {
            domReady(function () {
                // Do my stuff here...
            });
        });

 2. Use `$(document).ready()`:

        $(document).ready(function() {
            // Do my stuff here...
        });

**Which one should I choose, and why?**

 Both the options seems to work as expected. I am not confident in the jQuery&#39;s one because RequireJS is doing its magic; that is, since RequireJS will dynamically add scripts, I&#39;m worried that DOM ready may occur before all of the dynamically-requested scripts are loaded. Whereas, RequireJS will add a burden on additional JS just for `domReady` when I already have jQuery required.

## Questions

- Why does RequireJS provide a `domReady` plugin when we can have jQuery&#39;s `$(document).ready();`? I don&#39;t see any advantage of including another dependency.
- If its just to feed a need, then why not provide one for cross-browser AJAX?

As far as I know, a module that requires `domReady` won&#39;t be fetched or executed after the document is ready, and you could do the same requiring jQuery as well:

    require([&#39;jQuery&#39;], function ($) {
        $(document).ready(function () {
            // Do my stuff here...
        });
    });

To be more clear on my question: **what&#39;s the difference between requiring `domReady` or `jQuery`?**

We have two different way for doing function expression in JavaScript:

**Named function expression (NFE)**: 

    var boo = function boo () {
      alert(1);
    };

**Anonymous function expression**:

    var boo = function () {
      alert(1);
    };

And both of them can be called with `boo();`. I really can&#39;t see why/when I should use anonymous functions and when I should use Named Function Expressions. What difference is there between them?

I was studying Blobs, and I noticed that when you have an ArrayBuffer, you can easily convert this to a Blob as follows:

    var dataView = new DataView(arrayBuffer);
    var blob = new Blob([dataView], { type: mimeString });

The question I have now is, is it possible to go from a Blob to an ArrayBuffer?

    node.cloneNode(true); // deep copy

It doesn&#39;t seem to copy the event listeners that I added using `node.addEventListener(&quot;click&quot;, someFunc);`.

I am building an image resize/crop, and I&#39;d like to show a live preview after they&#39;ve edited it in a modal (bootstrap). This *should* work, I believe, but I just get 0 in console.log. This requires feeding the width and the height of the original image into another script (which I&#39;ll do after, just need them in console.log/a variable for now)

    function doProfilePictureChangeEdit(e) {
        var files = document.getElementById(&#39;fileupload&#39;).files[0];
        var reader = new FileReader();
        reader.onload = (function(theFile) {
            document.getElementById(&#39;imgresizepreview&#39;).src = theFile.target.result;

            document.getElementById(&#39;profilepicturepreview&#39;).src = theFile.target.result;
          }
        );
        reader.readAsDataURL(files);
        var imagepreview = document.getElementById(&#39;imgresizepreview&#39;);
        console.log(imagepreview.offsetWidth);
        $(&#39;img#imgresizepreview&#39;).imgAreaSelect({
            handles: true,
            enable: true,
            aspectRatio: &quot;1:1&quot;,
            onSelectEnd: preview
        });

I&#39;m developing a Chrome extension, and I&#39;d like users to be able to add their own CSS styles to change the appearance of the extension&#39;s pages (not web pages). I&#39;ve looked into using `document.stylesheets`, but it seems like it wants the rules to be split up, and won&#39;t let you inject a complete stylesheet. Is there a solution that would let me use a string to create a new stylesheet on a page?

I&#39;m currently not using jQuery or similar, so pure Javascript solutions would be preferable.

I&#39;ve always been confused between HTMLCollections, objects, and arrays when it comes to DOM.  For instance...

 1. What is the difference between `document.getElementsByTagName(&quot;td&quot;)` and `$(&quot;td&quot;)`?
 2. `$(&quot;#myTable&quot;)` and `$(&quot;td&quot;)` are objects (jQuery objects).  Why is console.log also showing the array of DOM elements beside them, and are they not objects and not an array?
 3. What is the elusive &quot;NodeLists&quot; all about, and how do I select one?

Please also provide any interpretation of the below script.

I&#39;m currently having a problem when passing an array to a directive via an attribute of that directive. I can read it as a String but i need it as an array so this is what i came up with but it doesn&#39;t work. Help anyone? thks in advance

Javascript::

    app.directive(&#39;post&#39;, function($parse){
        return {
            restrict: &quot;E&quot;,

                content: &quot;@&quot;,
                cover: &quot;@&quot;,
                date: &quot;@&quot;
            },
            templateUrl: &#39;components/postComponent.html&#39;,
            link: function(scope, element, attrs){
                scope.tags = $parse(attrs.tags)
            }
        }
    }

Passing array via attribute to AngularJS directive

I am trying to find a simple and fast way of counting the number of Objects in a list that match a criteria.
e.g.

    class Person:
        def __init__(self, Name, Age, Gender):
            self.Name = Name
            self.Age = Age
            self.Gender = Gender

    # List of People
    PeopleList = [Person(&quot;Joan&quot;, 15, &quot;F&quot;), 
                  Person(&quot;Henry&quot;, 18, &quot;M&quot;), 
                  Person(&quot;Marg&quot;, 21, &quot;F&quot;)]

Now what&#39;s the simplest function for counting the number of objects in this list that match an argument based on their attributes?
E.g., returning 2 for Person.Gender == &quot;F&quot; or Person.Age &lt; 20.

Python Count Elements in a List of Objects with Matching Attributes

I have an attribute directive restricted as follows:

     restrict: &quot;A&quot;

I need to pass in two attributes; a number and a function/callback, accessing them within the directive using the `attrs` object.

If the directive was an element directive, restricted with `&quot;E&quot;` I could to this:

    &lt;example-directive example-number=&quot;99&quot; example-function=&quot;exampleCallback()&quot;&gt;

However, for reasons I won&#39;t go into I need the directive to be an attribute directive.

**How do I pass multiple attributes into an attribute directive?**



How do I pass multiple attributes into an Angular.js attribute directive?

I have created an `Attribute` class called `RelatedPropertyAttribute`:

    [AttributeUsage(AttributeTargets.Property)]
    public class RelatedPropertyAttribute: Attribute
    {
        public string RelatedProperty { get; private set; }

        public RelatedPropertyAttribute(string relatedProperty)
        {
            RelatedProperty = relatedProperty;
        }
    }

I use this to indicate related properties in a class. Example of how I would use it:

    public class MyClass
    {
        public int EmployeeID { get; set; }
    
        [RelatedProperty(&quot;EmployeeID&quot;)]
        public int EmployeeNumber { get; set; }
    }

I would like to use lambda expressions so that I can pass a strong type into my attribute&#39;s constructor, and not a &quot;magic string&quot;.  This way I can exploit compiler type checking. For example:

    public class MyClass
    {
        public int EmployeeID { get; set; }
    
        [RelatedProperty(x =&gt; x.EmployeeID)]
        public int EmployeeNumber { get; set; }
    }

I thought I could do it with the following, but it isn&#39;t allowed by the compiler:

    public RelatedPropertyAttribute&lt;TProperty&gt;(Expression&lt;Func&lt;MyClass, TProperty&gt;&gt; propertyExpression)
    { ... }

Error: 

&gt; The non-generic type &#39;RelatedPropertyAttribute&#39; cannot be used with
&gt; type arguments

How can I achieve this?


Lambda expression in attribute constructor

I wrote a **custom view** that extends `RelativeLayout`. My view has text, so I want to use the standard `android:text` **without** the need to specify a `&lt;declare-styleable&gt;` and **without** using a custom namespace `xmlns:xxx` every time I use my custom view.

this is the xml where I use my custom view:

    &lt;my.app.StatusBar
        android:id=&quot;@+id/statusBar&quot;
        android:text=&quot;this is the title&quot;/&gt;

How can I get the attribute value? I think I can get the android:text attribute with 

    TypedArray a = context.obtainStyledAttributes(attrs,  ???);

but what is `???` in this case (without a styleable in attr.xml)?

https://stackoverflow.com/questions/3437786/how-to-get-web-page-size-browser-window-size-screen-size-in-a-cross-browser-wa

I&#39;m using this answer :

    var w = window,
        d = document,
        e = d.documentElement,
        g = d.getElementsByTagName(&#39;body&#39;)[0],
        x = w.innerWidth || e.clientWidth || g.clientWidth,
        y = w.innerHeight|| e.clientHeight|| g.clientHeight;

So I&#39;m able to fit my plot to the user&#39;s window like this :

	var svg = d3.select(&quot;body&quot;).append(&quot;svg&quot;)
			.attr(&quot;width&quot;, x)
			.attr(&quot;height&quot;, y)
		    .append(&quot;g&quot;);

Now I&#39;d like that something takes care of resizing the plot when the user resize the window.

PS : I&#39;m not using jQuery in my code.



Resize svg when window is resized in d3.js

I have created a d3 visualization that takes an array of data, creats a rect for each data point, and then displays the text in the rect. However, I have only gotten the text to display inside of the rect by giving it coordinates. I am wondering how I would tell it to center itself in the rect element. Here is the code:

    var elementTags = [&quot;Google&quot;, &quot;Amazon&quot;, &quot;Wikipedia&quot;, &quot;Yahoo!&quot;, &quot;Messi&quot;, &quot;Ronaldo&quot;, &quot;One&quot;, &quot;Two&quot;, &quot;Three&quot;,
    			 &quot;Monkey&quot;];
The next part creates arrays I used to position the rects

    			var xPosLoop = [0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3];
    			var yPosLoop = [0, 0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5]
set their width and height

    			var elementWidth = 210;
    			var elementHeight = 60;
create the svg container and add rects

    			var svgContainer = d3.select(&quot;body&quot;) //create container
    					.append(&quot;svg&quot;)
    					.attr(&quot;width&quot;, 1000)
    					.attr(&quot;height&quot;, 1000);
    			var enterElements = svgContainer.selectAll(&quot;rect&quot;) //draw elements
    					.data(elementTags).enter().append(&quot;rect&quot;)
    					.attr(&quot;x&quot;, function(d, i){
    						return xPosLoop[i]*(elementWidth+25);
    					})
    					.attr(&quot;height&quot;, elementHeight)
    					.attr(&quot;y&quot;, function(d, i){
    						return yPosLoop[i]*(elementHeight+35);
    					})
    					.attr(&quot;width&quot;, elementWidth)
    					.attr(&quot;rx&quot;, 4)
    					.attr(&quot;fill&quot;, &quot;steelblue&quot;)
    					.attr(&quot;stroke&quot;, &quot;black&quot;)
    					.attr(&quot;stroke-width&quot;, 1);
    			var addText = svgContainer.selectAll(&quot;text&quot;).data(elementTags).enter().append(&quot;text&quot;);
and here is where i tell the text where to display, it&#39;s also where I need help. I want the text to center itself in the rects automatically.

    			var textElements = addText
    				.attr(&quot;x&quot;, function(d, i){
    					return ((xPosLoop[i]*(elementWidth+25) +elementWidth/2))
    				})
    				.attr(&quot;y&quot;, function(d, i){
    					return ((yPosLoop[i]*(elementHeight+35)) + elementHeight/2 + 3)
    				})
    				.attr(&quot;font-family&quot;, &quot;Arial Black&quot;)
    				.attr(&quot;font-size&quot;, &quot;20px&quot;)
    				.attr(&quot;fill&quot;, &quot;white&quot;)
    				.text(function(d, i){return d;});

How to center text in a rect element in d3?

I just wanted to get the mouse position using D3 by using the following code:
  
    var x = 0;

    svg.on(&#39;mousemove&#39;, function () {
       x = d3.mouse(this)[0];         
    });

but `x` is always equal to `0`. By using `console.log()`, I can see that `x` value is getting changed just inside the `function()` but out of it `x` got its initial value of `0`.

How can I save the `x` value and use it later in my application?

Mouse position in D3

I&#39;m trying to display different data on a graph. The user can change the displayed data clicking on a radio button. I&#39;m using a &quot;Bubble chart&quot; to render the data.

For each type of data I need to update the Yaxis (the domain is different).
Here is what I&#39;ve done for now:

#Chart initialisation

    var svg = d3.select(&quot;body .main-content&quot;).append(&quot;svg&quot;)
        .attr(&quot;class&quot;, &quot;chart&quot;)
        .attr(&quot;width&quot;, width)
        .attr(&quot;height&quot;, height);

#Initialise the Axis

    initAxis();
    function initAxis()
    {
        var y = d3.scale.linear().domain([0,1000]).range([height-margin, margin]).nice(),
            x = d3.scale.linear().domain([0,23]).range([margin,width-margin]),
            yAxis = d3.svg.axis().scale(y).orient(&quot;left&quot;),
            xAxis = d3.svg.axis().scale(x).orient(&quot;bottom&quot;);
    
        svg.append(&quot;g&quot;)
            .attr(&quot;class&quot;, &quot;y axis&quot;)
            .attr(&quot;transform&quot;, &quot;translate(&quot; + margin + &quot;,0)&quot;)
            .call(yAxis);
    
        svg.append(&quot;g&quot;)
            .attr(&quot;class&quot;, &quot;x axis&quot;)
            .attr(&quot;transform&quot;, &quot;translate(0,&quot; + (height - margin) + &quot;)&quot;)
            .call(xAxis);
    }

#Update the chart

        

        function update(type)
        {
            // Get the data
            type = type || &#39;default&#39;;
            var m = max[type],
                mi = min[type]+0.1,
                data = dataset[type],
                step = stp[type];

            // Set the functions
            var y = d3.scale.linear().domain([mi,m]).range([height-margin, margin]).nice();
            var o = d3.scale.linear().domain([0,m]).range([.5,1]);
            var r = d3.scale.linear().domain([0,Math.sqrt(m)]).range([0,30]);
            var x = d3.scale.linear().domain([0,23]).range([margin,width-margin]);
            var color = function (a, b) {
                for (var c = (a - 0) / (m - 0), d = [], e = 0; 3 &gt; e; e++) d.push(Math.round(K[0][e] +
                        c * (K[1][e] - K[0][e])));
                d.push(b || 0.7);
                return &quot;rgba(&quot; + d.join(&quot;,&quot;) + &quot;)&quot;
            }

            //Attach the data to the graph
            var circle = svg.selectAll(&quot;circle&quot;).data(data);

            // Update existing element
            circle.attr(&quot;class&quot;, &quot;update&quot;);

            // Add new element
            circle.enter()
                .append(&quot;circle&quot;)
                .attr(&quot;class&quot;, &quot;enter&quot;)
                .attr(&quot;stroke-width&quot;, 0)
                .attr(&quot;stroke&quot;, &quot;black&quot;)
                    .transition()
                    .duration(750)
                    .attr(&quot;y&quot;, 0)
                    .style(&quot;fill-opacity&quot;, 1);

            // Apply attribute to new and updated element
            circle.attr(&quot;cx&quot;, function(d,i) {return x(d.h);})
                .attr(&quot;cy&quot;, function(d,i) {return y(d.v);})
                .attr(&quot;r&quot;, function(d,i) {return r(Math.sqrt(d.v));})
                .style(&quot;fill&quot;, function(d,i) {return color(d.v);})
                .style(&quot;opacity&quot;, function(d,i) {return o(d.v);})
                .on(&quot;click&quot;, function(d,i){window.open(d.name,&#39;_blank&#39;);})
                .on(&quot;mouseover&quot;, function(d,i){d3.select(this).style(&quot;fill&quot;, &quot;red&quot;).attr(&quot;stroke-width&quot;, 1);})
                .on(&quot;mouseout&quot;, function(d,i){d3.select(this).style(&quot;fill&quot;, function(d,i) {return color(d.v);}).attr(&quot;stroke-width&quot;, 0);})
                .append(&quot;title&quot;)
                .text(function(d) { return d.v+&#39; &#39;+ d.t+&#39; (adjusted) - &#39;+ d.d })
                    .transition()
                    .duration(750)
                    .attr(&quot;y&quot;, 0)
                    .style(&quot;fill-opacity&quot;, 1);

            // Remove old elements
            circle.exit()
                .attr(&quot;class&quot;, &quot;exit&quot;)
                .transition(750)
                .ease(&quot;linear&quot;)
                .attr(&quot;cy&quot;, 0)
                .style(&quot;opacity&quot;, 0.2)
                .remove();

            // Update the Axis
            var xAxis = d3.svg.axis().scale(x).orient(&quot;bottom&quot;);
            var yAxis = d3.svg.axis().scale(y).orient(&quot;left&quot;);

            svg.selectAll(&quot;g .y.axis&quot;)
                .call(yAxis)

            svg.selectAll(&quot;g .x.axis&quot;)
                .call(xAxis);
        }

The circles are updated correctly (transitions are not working tho) but the axis are not changing and I can&#39;t see why. I&#39;m a bit lost, I&#39;ve looked at many example but I cannot see what I&#39;m doing wrong.

I&#39;m using d3.js version: v3.1.10
