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?

• Felix Kling: Where do you get the name/URL from?
• NLV: I set in the code behind - C#.
• NLV: I want everything pageURL. It is not going to change. Can i do it? A specific function taking pageURL as parameter is fine.
• Felix Kling: @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: @NLV: HTML encoding != URL encoding: en.wikipedia.org/wiki/Percent-encoding

Answer 1

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

Answer 2

have u considered (削除) html (削除ここまで) url encoding the pageURL parameter?

this would greatly simplify your task

• NLV: Okie, can you explain how it would help me?
• NLV: No clues. Getting stuck in the same issue. Any ideas?
• elmac: easy...everything after the first "=" in your name is your parameter. just decode it back and you got yourself an url.
• elmac: 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 ;)
• NLV: 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.
