Getting Query Parameter from a URL which inturn has some URL with Query parameters

Question

I've the following URL

http://somesite/somepage.aspx

I pass a query parameter value which has another URL with query parameters like this.

http://somesite/somepage.aspx?pageURL=http://someothersite/someotherpage.aspx?param1=value&source=http://anotheronesite/anotherpage

I need to get the pageURL value as the one in the bold letters. But i'm getting

http://someothersite/someotherpage.aspx?param1=value

and i'm not getting the source param. I'm using the following JavaScript function -

  function getParameterByName( name )
  {
     name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
     var regexS = "[\\?&]"+name+"=([^&#]*)";
     var regex = new RegExp( regexS );
     var results = regex.exec( window.location.href );
     if( results == null )
       return "";
     else
       return decodeURIComponent(results[1].replace(/\+/g, " "));
  }

Any ideas?

I want everything pageURL. It is not going to change. Can i do it? A specific function taking pageURL as parameter is fine. — NLV

@NLV: I have no clue about C# but maybe this helps you: stackoverflow.com/questions/1380617/request-url-parameter Anyway, you have to encode the & so that it is not recognized as parameter of the "base URL". — Felix Kling

You need to use URL encoding to encode the parameter. Otherwise & is treated as reserved character and belongs to the "base URL".

Okie, can you explain how it would help me?

No clues. Getting stuck in the same issue. Any ideas?

easy...everything after the first "=" in your name is your parameter. just decode it back and you got yourself an url.

or to say it plain: your script should work given the pageURL thingy is encoded. just don't forget to encode it back. jquery has htmlEncode and htmlDecode ;)

Okie when i encode it just & is replaced by &amp. Nothing else. So still & is preceeding the source link and it is not fetched by that JS function.
