like 

    $(&quot;tr td:nth-child(2)&quot;)


  [1]: http://api.jquery.com/nth-child-selector/

the [eq api][1] should do this for you

    $(&quot;table td&quot;).eq(n)

    $(&#39;#id td:nth-child(3)&#39;);

    ~$ python -V
     Python 3.2.1

but I get into problems when I run some python programs. my guess is (or at least I want to try this) that there is some backward compatibility issues, and I want to run those python scripts with 

     python2 2.7.2-2

which is also installed on my system but I do not know how to make it as the (temporary) default python. The python script starts with

     #!/usr/bin/env python

and I am using arch linux.

python 2 instead of python 3 as the (temporary) default python?

I&#39;m using the underscore.js templating function and have done a template like this: 

    &lt;script type=&quot;text/template&quot; id=&quot;gridItem&quot;&gt;
		&lt;div class=&quot;griditem &lt;%= gridType %&gt; &lt;%= gridSize %&gt;&quot;&gt;
			&lt;img src=&quot;&lt;%= image %&gt;&quot; /&gt;
			&lt;div class=&quot;content&quot;&gt;
				&lt;span class=&quot;subheading&quot;&gt;&lt;%= categoryName %&gt;&lt;/span&gt;
				&lt;% if (date) { %&gt;&lt;span class=&quot;date&quot;&gt;&lt;%= date %&gt;&lt;/span&gt;&lt;% }  %&gt;
				&lt;h2&gt;&lt;%= title %&gt;&lt;/h2&gt;
			&lt;/div&gt;
		&lt;/div&gt;
	&lt;/script&gt;

As you can see I have an if statement in there because all of my models won&#39;t have the date parameter. However this way of doing it gives me an error `date is not defined`. So, how can I do if statements within a template?

Anybody know of a lightweight yet durable database, written in Javascript, that can be used with Node.js. 

I don&#39;t want the &#39;weight&#39; of (great) solutions like Mongo or Couch. A simple, in memory JS database with the capability to persist to disk as a file would be enough. I would only use it to store small amounts of data. 

Requirements:

- can run in process with a node.js server application
- can save the whole database to disk and recover after a failure
- NO need for atomic writes or transaction supports
- fast queries and sorting would be nice
- only needs to support small data volumes, up to 1MB in total

I&#39;ve come across TAFFY db so far but it really doesn&#39;t seem optimized for use in Node.js. Anybody seen what I&#39;m looking for out there?

Thanks

I was wondering if there&#39;s a way to do something like a PHP `foreach` loop in JavaScript. The functionality I&#39;m looking for is something like this PHP Snippet:

    foreach($data as $key =&gt; $value) { }

I was looking at the JS `for..in` loop, but there seems to be no way to specify the `as`. If I do this with a &#39;normal&#39; for loop (`for(var i = 0; i &lt; data.length; i++`), is there a way to grab the key =&gt; value pairs?

For..In loops in JavaScript - key value pairs

Is there a JQuery selector to select all elements which do **not** have certain child element as a direct child? For example:

    &lt;p&gt;
        text in paragraph
    &lt;/p&gt;
    &lt;p&gt;
        &lt;div&gt;text in div&lt;/div&gt;
    &lt;/p&gt;

I want to select only `&lt;p&gt;`s like the first one (without a `&lt;div&gt;` child). *Is this possible?*

Further information: Actually I&#39;m trying to insert a `&lt;div&gt;` into all those `&lt;p&gt;` that do not have one by an expression like this:
    
    $(&#39;p&#39;).wrapInner(&#39;&lt;div /&gt;&#39;)

But this would add an additional `&lt;div&gt;` to the second `&lt;p&gt;`.

Why would `JSON.stringify()` return:

    []

The same happens with jQuery: `$.JSON.encode()`

What could cause this? I am passing in a simple array of objects, where each object has string properties. I have looped through and alerted each objects properties and all looks fine, but for some reason both the encode methods are returning `[]`.

JSON.stringify returning []

I&#39;m doing a loop through few input elements of &#39;checkbox&#39; type. After that, I&#39;m adding values and checked attributes to an array. This is my code:

    var stuff = {};
    $(&#39;form input[type=checkbox]&#39;).each(function() {
        stuff[$(this).attr(&#39;value&#39;)] = $(this).attr(&#39;checked&#39;);
    });

This works fine, but I&#39;m just wondering if I can do the exact same thing with .push() method in Jquery?

I&#39;ve tried something like this but it doesn&#39;t work:

    stuff.push( {$(this).attr(&#39;value&#39;):$(this).attr(&#39;checked&#39;)} );

**Edit:**

I was trying to use .push() method on Object, but .push() is actually just a method of Array Object.

What is the difference in usage between `$.data` and `$.attr` when using `data-someAttribute`?

My understanding is that `$.data` is stored within jQuery&#39;s `$.cache`, not the DOM. Therefore, if I want to use `$.cache` for data storage, I should use `$.data`. If I want to add HTML5 data-attributes, I should use `$.attr(&quot;data-attribute&quot;, &quot;myCoolValue&quot;)`.

jQuery Data vs Attr?

I&#39;m using jackson to convert an object of mine to json.
The object has 2 fields:

    @Entity
    public class City {
       @id
       Long id;
       String name;
       public String getName() { return name; }
       public void setName(String name){ this.name = name; }
       public Long getId() { return id; }
       public void setName(Long id){ this.id = id; }
    }

Since I want to use this with the jQuery auto complete feature I want &#39;id&#39; to appear as &#39;value&#39; in the json and &#39;name&#39; to appear as &#39;label&#39;. The documentation of jackson is not clear on this and I&#39;ve tried every annotation that even remotely seems like it does what I need but I can&#39;t get `name` to appear as `label` and `id` to appear as `value` in the json.

Does anyone know how to do this or if this is possible?

I am creating a page in JSP where I have a dropdown list and once the user selects a value he has to click on the go button and then the value is sent to the Servlet.

                &lt;/select&gt;
                &lt;input type=&quot;submit&quot; name=&quot;GO&quot; value=&quot;Go&quot;/&gt;

How do I make it so that it does it on change? E.g. when the user selects John all his details are retrived from the DB and displayed. I want the system to do it without having to click the go button.

How to submit form on change of dropdown list?

Let&#39;s say I have

    &lt;div class=&quot;myDiv&quot;&gt;Hi there&lt;/div&gt;

I want to put a `background-image` and give it an `opacity` of `0.5` – but I want that the text I have written will have full opacity (`1`). 

If I would write the CSS like this

&lt;!-- language: lang-css --&gt;

    .myDiv { opacity:0.5 }

 **everything** will be in low opacity – and I don&#39;t want that.

So my question is – How can I get low-opacity background image with full opacity text?

Can I set an opacity only to the background image of a div?

I&#39;m looking for the html code for the dot. Not the dot that&#39;s at the end of sentences but the dot that&#39;s used to separate items horizontally.

    Item 1 . Item 2 . Item 3

The traditional dot is centered on the bottom of the line while the dot I&#39;m looking for is centered on the middle.
