    function getURLParameter(name) {
      return decodeURIComponent((new RegExp(&#39;[?|&amp;]&#39; + name + &#39;=&#39; + &#39;([^&amp;;]+?)(&amp;|#|;|$)&#39;).exec(location.search) || [null, &#39;&#39;])[1].replace(/\+/g, &#39;%20&#39;)) || null;
    }

So you can use:

    myvar = getURLParameter(&#39;myvar&#39;);

Is there a nicer way of doing the following:  
I need a check for null to happen on file.Headers before proceeding with the loop  

    if (file.Headers != null)
    {
      foreach (var h in file.Headers)
      {
       //set lots of properties &amp; some other stuff
      }
    }

In short it looks a bit ugly to write the foreach inside the if due to the level of indentation happening in my code.

Is something that would evaluate to 

    foreach(var h in (file.Headers != null))
    {
      //do stuff
    }

possible?

I just did some changes to the `.vimrc` file and `.bash_aliases` file and from that time I can&#39;t delete words with backspace key.

My `.vimrc` file has:

    set nocompatible

    set number
    set incsearch
    set autoindent
    set ruler
    set autowrite
    set smarttab
    set linebreak
    set spell
    set et
    set title

    set mouse=v
    set history=50
    set tabstop=4
    set matchtime=2
    set matchpairs+=&lt;:&gt;

    syntax enable
    filetype plugin indent on
    filetype indent on
    set sw=4

    map &lt;f2&gt; :w\|!python %

    hi SpellBad ctermfg=000 guifg=#000

And my `.bash_aliases` file has two line for Vim:

    alias vim=&quot;vim -c &#39;startinsert&#39; -u ~/.vim/.vimrc&quot;
    alias vi=&quot;vi -c &#39;startinsert&#39; -u ~/.vim/.vimrc&quot;

My `~/.vim` directory doesn&#39;t have a single plugin or script, so there&#39;s isn&#39;t any chance that plugin will cause this.

`~/.vim/.vimrc` is a symlink. The actual `.vimrc` file is in `~/vimrc/` directory which is a git repository.

I&#39;m trying to add the [Ace editor][1] to a page, but I don&#39;t know how to get the height to be set automatically based on the length of its contents.

Ideally it would work so when the content changes the height is recalculated, but I would be happy with the height just being set on page load.

For a JavaScript novice can someone help me figure out how I work out the length of the code, how many lines it spans, what the new height is and how I update the DOM to reflect this?

I found [this suggestion][2] in a Google group, but I don&#39;t really understand what it&#39;s doing and how I get it to adjust the height.

    editor.getSession().getDocument().getLength() *
    editor.renderer.lineHeight + editor.renderer.scrollBar.getWidth()

I am trying to change a hashed URL (document.location.hash) with the replace method, but it doesn&#39;t work.

    $(function(){
     var anchor = document.location.hash;
     //this returns me a string value like &#39;#categories&#39;

      $(&#39;span&#39;).click(function(){

         $(window).attr(&#39;url&#39;).replace(anchor,&#39;#food&#39;);
         //try to change current url.hash &#39;#categories&#39;
         //with another string, I stucked here.
      });

    });

I dont want to change/refresh page, I just want to replace URL without any responses.

Note: I don&#39;t want to solve this with a href=&quot;#food&quot; solution.

How can I replace a window&#39;s URL hash with another response?

I have a dateformat like this `&#39;2010-10-11T00:00:00+05:30&#39;`. I have to format in to `MM/dd/yyyy` using JavaScript or jQuery . Anyone help me to do the same.

I have this string:

    My name is &lt;b&gt;Bob&lt;/b&gt;, I&#39;m &lt;b&gt;20&lt;/b&gt; years old, I like &lt;b&gt;programming&lt;/b&gt;.

I&#39;d like to get the text between `b` tags to an array, that is:

    [&#39;Bob&#39;, &#39;20&#39;, &#39;programming&#39;]

I tried this `/&lt;b&gt;(.*?)&lt;\/b&gt;/.exec(str)` but it will only get the first text.

Regex match text between tags

JSLint is not passing this as a valid code:

    /* global someVar: false */
    if (typeof someVar === &quot;undefined&quot;) {
        var someVar = &quot;hi!&quot;;
    }

What is the correct way?
