Sure - just pass an empty string:

    var arr2 = arr.join(&#39;&#39;);

I am sending information between client and Django server, and I would like to use JSON to this. I am sending simple information - list of strings. I tried using `django.core.serializers`, but when I did, I got 

    AttributeError: &#39;str&#39; object has no attribute &#39;_meta&#39;

It seems this can be used only for Django objects. How can I serialize simple, Python objects?

I am still struggling with drawing a line with CGContext.  I have actually go to line to draw, but now I need the background of the Rect to be transparent so the existing background shows thru.  Here&#39;s my test code: 

    (void)drawRect:(CGRect)rect
    {
        CGContextRef context = UIGraphicsGetCurrentContext();
        CGContextSetFillColorWithColor(context, [UIColor clearColor].CGColor);
        CGContextSetAlpha(context,0.0);
        CGContextFillRect(context, rect);
        
        CGContextSetStrokeColorWithColor(context, [UIColor whiteColor].CGColor);
        CGContextSetLineWidth(context, 5.0);
        CGContextMoveToPoint(context, 100.0,0.0);
        CGContextAddLineToPoint(context,100.0, 100.0);
        CGContextStrokePath(context);
    }
Any ideas?


Setting A CGContext Transparent Background

    var arr= [&#39;g&#39;,&#39;o&#39;,&#39;o&#39;,&#39;d&#39;];
    var arr2 = arr.join();

Arr2 will be &quot;g,o,o,d&quot;. I would like to get &quot;good&quot;. I know there are a million other ways to achieve this but was curious if there was a way with join.

I have a jquery slider that I have built, basically just three pannels that slide by applying negative left CSS values. Works great, but I have a youtube video in one slide that wont stop when I slide. I&#39;ve tried display:none and Visibility:hidden which works in all but IE, the audio keeps going in IE.

Is there an easy way to kill a video with jquery?

How do I pass context into `setTimeout`? I want to call `this.tip.destroy()` if `this.options.destroyOnHide` after 1000 ms. How can I do that?

    if (this.options.destroyOnHide) {
         setTimeout(function() { this.tip.destroy() }, 1000);
    } 

When I try the above, `this` refers to the window.

I have this jQuery toggle. It work fine.

       &lt;ul&gt;
        &lt;li&gt;Go to the store&lt;/li&gt;
        &lt;li&gt;Pick up dinner&lt;/li&gt;
        &lt;li&gt;Debug crash&lt;/li&gt;
        &lt;li&gt;Take a jog&lt;/li&gt;
      &lt;/ul&gt;

&amp;nbsp;
      
            $(&quot;li&quot;).toggle(
              function () {
                $(this).css({&quot;list-style-type&quot;:&quot;disc&quot;, &quot;color&quot;:&quot;blue&quot;});
              },
              function () {
                $(this).css({&quot;list-style-type&quot;:&quot;disc&quot;, &quot;color&quot;:&quot;red&quot;});
              },
              function () {
                $(this).css({&quot;list-style-type&quot;:&quot;&quot;, &quot;color&quot;:&quot;&quot;});
              }
            );
        
        

The problem is when I do fast clicking, it highlighted the text in it. 
Is there a way to stop the text from being highlighted?

disable text highlighting on double click in jQuery

I need to execute a piece of JavaScript code say, each 2000 milliseconds.

    setTimeout(&#39;moveItem()&#39;,2000)

The above will execute a function after 2000 milliseconds, but won&#39;t execute it again.

So inside my moveItem function I have:

    function moveItem() {
    	jQuery(&quot;.stripTransmitter ul li a&quot;).trigger(&#39;click&#39;);
    	setInterval(&#39;moverItem()&#39;,2000);
    }

This does not work because I want to execute the trigger click jQuery piece of code each interval of 2000 milliseconds, but right now it is being called all the time and the script needs to be interrupted. Besides that, I feel this is very bad quality coding... How would you guys solve this?

Loop timer in JavaScript

Let&#39;s say I have `var a = function() { return 1; }`. Is it possible to alter `a` so that `a()` returns `2`? Perhaps by editing a property of the `a` object, since [every function is an object][1]?

**Update:** Wow, thanks for all the responses. However, I&#39;m afraid I wasn&#39;t looking to simply reassign a variable but actually edit an existing function. I am thinking along the lines of how you can combine [partial functions][2] in Scala to create a new `PartialFunction`. I am interested in writing something similar in Javascript and was thinking that the existing function could perhaps be updated, rather than creating an entirely new `Function` object.
