What would you like to do?
get query variable

use like this:

getQueryVariable("foo")

To get variables in urls eg:

http://foo.com/index.html?foo=bar

If you want to support arrays, check the version by @atk below:

function(a){
return RegExp("[&?]"+a+"=([^&]+)").exec(location)[1]
}
//searches the url (location)
//finds the text after a "&" or a "?" followed by the variable name, followed by a "="
//and before another "&"
function(a){return RegExp("[&?]"+a+"=([^&]+)").exec(location)[1]}
//If you want to support arrays (Thanks atk!)
function(a){for(var b=[],c,d=eval('/[&?]'+a+'(\\[])?=([^&]+)/g');c=d.exec(location);)b.push(c[2]);return b}
{
"name": "getQueryVariable",
"description": "Get variables in urls",
"keywords": [
"url",
"query",
"string",
"variable",
"get"
]
}
<script>
getQueryVariable = function(a){return RegExp("[&?]"+a+"=([^&]+)").exec(location)[1]}
document.write(getQueryVariable("foo"))
</script>

Only 1 char longer:
function(a){for(var b=[],c,d=eval('/[&?]'+a+'(\\[])?=([^&]+)/g');c=d.exec(location);)b.push(c[2]);return b}

If you have an anchor on url like param=value#anchor it returns the value like value#anchor, you just need to add one more byte to the code to works =D

function url(a){for(var b=[],c,d=eval('/[&?]'+a+'([])?=([^&^#]+)/g');c=d.exec(location);)b.push(c[2]);return b}
