Try [`myJQueryElement.get(0)`](http://api.jquery.com/get/) or `myJQueryElement[0]`. (`get()` is most useful when you need negative indices, for example, as described in the documentation for `get()`.)

&lt;code&gt;$(&quot;#foo&quot;)[0]&lt;/code&gt; will get you an HTML element.  Using brackets is a tiny bit faster than using &lt;code&gt;.get()&lt;/code&gt; but not something you&#39;ll likely notice unless you are doing it [millions of times][1].

What is best practice when closing a C# application?

I have read that you can use:

    Environment.Exit(0); or Application.Exit();

But what is the difference?

Furthermore, with regards to Environment.Exit(0), I have used exit codes before when working with Java but have never fully understood their purpose. What role do they play when exiting an application in C#?

Is it not possible with NUnit to go the following?

&lt;!-- language: lang-cs --&gt;

    [TestCase(new DateTime(2010,7,8), true)]
    public void My Test(DateTime startdate, bool expectedResult)
    {
        ...
    }

I really want to put a `datetime` in there, but it doesn&#39;t seem to like it. The error is:

&gt; An attribute argument must be a constant expression, typeof expression
&gt; or array creation expression of an attribute parameter type

Some documentation I read seems to suggest you should be able to, but I can&#39;t find any examples.

A relative of mine who started to learn Web Development asked me this question. 

Why `&lt;script src=&quot;min.js&quot;&gt;&lt;/script&gt;` and `&lt;link rel=&quot;stylesheet&quot; href=&quot;min.css&quot;&gt;`? Why not `&lt;style href=&quot;min.css&quot;&gt;&lt;/style&gt;`. Why do we use `link` tag to add external CSS in the page but when we link CSS to page but we use `&lt;style&gt;...&lt;/style&gt;` when we write CSS inside `&lt;head&gt;`?

I told him that it&#39;s because of spec. Is there any more info to give to him?

Why do we use &lt;script&gt; for scripts, but not &lt;style&gt; for external CSS?

I am using [this script][1] to make a style object of all the inherited, etc. styles.

    var style = css($(this));
    alert (style.width);
    alert (style.text-align);

With the following, the first alert will work fine, but the second one doesn&#39;t... it&#39;s interpreting the `-` as a minus I assume. The debugger says &#39;uncaught reference error&#39;. I can&#39;t put quotes around it, though, because it isn&#39;t a string. So how do I use this object property?

How do I reference a JavaScript object property with a hyphen in it?

Referred to as the &quot;JavaScript console&quot;, when you click on a link, the log is cleared.

Is there a way to stop this log from being cleared when you click on a link?

The problem is that an event triggered onClick is returning an error which makes it harder to diagnose because the error is only displayed for a short time before being cleared.

Thanks.

I wanted to add the elements of an array into another, so I tried this:

    [1,2] + [3,4]

It responded with:

    &quot;1,23,4&quot;

What is going on?

Why is [1,2] + [3,4] = &quot;1,23,4&quot; in JavaScript?

I&#39;ve run into a unique situation that I have so far been unable to find a solution for: dynamically assigning a value to a CSS style.  I know how to use jQuery to assign width, height, etc. to an element, but what I&#39;m trying to do is actually change the value defined in the stylesheet so that the dynamically-created value can be assigned to multiple elements.  

What I&#39;m building is a slideshow of images that occupy the full viewport, recalculating the image&#39;s width, height, and left properties on resize so that the image is always centered, favors width over height, except when the viewport is taller than it is wide (resizing does not reload the page, just fires a function to resize the image).  

I have successfully been able to get it to work on one image, and now I&#39;m trying to determine the best way to assign those property values to all images in the slideshow without having to specify those three things individually for every image.  

My Question:
------------

Can the values of properties in a class be modified on the fly?  I&#39;m sure the answer is out there, I&#39;m probably just not using the correct terminology in my searches.  Hope I did a good job of describing the problem.  TIA.

Modifying CSS class property values on the fly with JavaScript / jQuery

I am using [Flot][1] to graph some of my data and I was thinking it would be great to make this graph appear fullscreen (occupy full space on the monitor) upon clicking on a button. Currently, my `div` is as follows:

    &lt;div id=&quot;placeholder&quot; style=&quot;width:800px;height:600px&quot;&gt;&lt;/div&gt;

Of course, the style attribute is only for testing. I will move this to `CSS` after during the actual design. Is there anyway I could make this div fullscreen and still preserve all event handling?

Change content of div - jQuery

I&#39;m trying to target page-wide links that do not start with a &#39;#&#39; and do not include in-line javascript but I&#39;m having problems figuring out how to structure the selector properly.

Based on what I&#39;ve googled about multiple selectors this should work, both selectors work independently, just not together!
   
    $(&#39;a:not([href*=javascript]), a:not([href^=#])&#39;)
	.each(function(){...

&lt;!-- End of automatically inserted text --&gt;

I have noticed a lot of jQuery plugins start with 

    ;(function(){ /* something in here */ })();

I just wondered what the beginning semi-colon was for, as well as the empty parentheses at the end.

What&#39;s the purpose of starting semi colon at beginning of JavaScript?

Say I have this:

    &lt;div class=&quot;class1 class2&quot;&gt;&lt;/div&gt;

How do I select this `div` element?

    document.getElementsByClassName(&#39;class1&#39;)[0].getElementsByClassName(&#39;class2&#39;)[0]

That does not work.

I know that, in jQuery, it is `$(&#39;.class1.class2&#39;)`, but I&#39;d like to select it with vanilla JavaScript.

How to get elements with multiple classes

Is it possible, using jQuery, to find out the type of an element with jQuery? For example, is the element a div, span, select, or input?

For example, if I am trying to load values into a drop-down list with jQuery, but the same script can generate code into a set of radio buttons, could I create something like:

    $(&#39;.trigger&#39;).live(&#39;click&#39;, function () {
       var elementType = $(this).prev().attr(WHAT IS IT);
    });

Given a drop-down list with a button next to it with the **trigger** class, my `elementType` variable should return `select` upon the button being pressed.

Get element type with jQuery

I&#39;ve seen a lot of different styles (and few different methods) of creating elements in jQuery. I was curious about the **clearest** way to build them, and also if any particular method is objectively better than another for any reason. Below are some *examples* of the styles and methods that I&#39;ve seen.

    var title = &quot;Title&quot;;
    var content = &quot;Lorem ipsum&quot;;
    
    // escaping endlines for a multi-line string
    // (aligning the slashes is marginally prettier but can add a lot of whitespace)
    var $element1 = $(&quot;\
        &lt;div&gt;&lt;h1&gt;&quot; + title + &quot;&lt;/h1&gt;\
            &lt;div class=&#39;content&#39;&gt;  \
            &quot; + content + &quot;        \
            &lt;/div&gt;                 \
        &lt;/div&gt;                     \
    &quot;);
    
    // all in one
    // obviously deficient
    var $element2 = $(&quot;&lt;div&gt;&lt;h1&gt;&quot; + title + &quot;&lt;/h1&gt;&lt;div class=&#39;content&#39;&gt;&quot; + content + &quot;&lt;/div&gt;&lt;/div&gt;&quot;);
    
    // broken on concatenation
    var $element3 = $(&quot;&lt;div&gt;&lt;h1&gt;&quot; +
                    title + 
                    &quot;&lt;/h1&gt;&lt;div class=&#39;content&#39;&gt;&quot; +
                    content +
                    &quot;&lt;/div&gt;&lt;/div&gt;&quot;);
    
    // constructed piecewise
    // (I&#39;ve seen this with nested function calls instead of temp variables)
    var $element4 = $(&quot;&lt;div&gt;&lt;/div&gt;&quot;);
    var $title = $(&quot;&lt;h1&gt;&lt;/h1&gt;&quot;).html(title);
    var $content = $(&quot;&lt;div class=&#39;content&#39;&gt;&lt;/div&gt;&quot;).html(content);
    $element4.append($title, $content);
    
    $(&quot;body&quot;).append($element1, $element2, $element3, $element4);

Please feel free to demonstrate any other methods/styles you might use.

Clearest way to build html elements in jQuery

Using jQuery, how can I get the input element that has the caret&#39;s (cursor&#39;s) focus?   

Or in other words, how to determine if an input has the caret&#39;s focus?



How to get the focused element with jQuery?

I have two lists with different objects in them.

    List&lt;Object1&gt; list1;
    List&lt;Object2&gt; list2;

I want to check if element from list1 exists in list2, based on specific attribute (Object1 and Object2 have (among others),  one mutual attribute (with type Long), named attributeSame).

right now, I do it like this:

    boolean found = false;
    for(Object1 object1 : list1){
       for(Object2 object2: list2){
           if(object1.getAttributeSame() == object2.getAttributeSame()){
               found = true;
               //also do something
           }
        }
        if(!found){
            //do something
        }
        found = false;
    }
But I think there is a better and faster way to do this :)
Can someone propose it?

Thanks!
