JavaScript and URL Info

via HTTP GET

[circuitjump]

Hi all,
I want to know if anyone knows of a way that Client-Side JavaScript can be used to get the information off of a URL string. (Example -- [somesite.com...]

I can't find anything on it. Just wanna see if anyone here can please come to the rescue!

Thanks :)

You can access the querystring section using (the ? onwards)

window.location.search

for the main part of the URL (up to the ?) just use

window.location

Cool,
Now to stripping the unwanted info. How do I go about doing that?

?string=20

The bolded part is what I want. I'm sure there is a function in JS or would I have to go about building one?

thanks

The following function returns an associative array of the values. Using your URL example:

var urlArgs = cbeGetURLArguments();

var s = parseInt(urlArgs['string']);

function cbeGetURLArguments() {
 var idx = location.href.indexOf('?');
 var params = new Array();
 if (idx != -1) {
  var pairs = location.href.substring(idx+1, location.href.length).split('&');
  for (var i=0; i<pairs.length; i++) {
   nameVal = pairs[i].split('=');
   params[i] = nameVal[1];
   params[nameVal[0]] = nameVal[1];
  }
 }
 return params;
}

Hi,

I ended up doing this and it worked great. I have the comment code on here in case someone else desides to use it.

// Grab the querystring if there is one.
var querystring = window.location.search;

// Strip the unwanted data and grab the number.
var querystringValue = querystring.substring(querystring.indexOf("=") +1, querystring.length);

If you are grabbing a number from the querystring, add a -0 at the end or else JS is going to think it's just another normal character that has no numeric value.

// Here we have to add "-0" at the
// end of the variable so that it
// treats it as a numeric value.
var number = querystringValue-0;

Thank you all :)
