how do i parse variables in the URL using javascript

I can pass the variable to next page. Depending on the choice chosen, i have a function which will execute the URL. Does anyone have a code in javascript function call another function. Please Help....!

Here is the code in java for you for the same you wanted :

Code:

---

function QueryString(key)
{
var value = null;
for (var i=0;i<QueryString.keys.length;i++)
{
if (QueryString.keys[i]==key)
{
value = QueryString.values[i];
break;
}
}
return value;
}
QueryString.keys = new Array();
QueryString.values = new Array();

function QueryString_Parse()
{
var query = window.location.search.substring(1);
var pairs = query.split("&");

for (var i=0;i<pairs.length;i++)
{
var pos = pairs[i].indexOf('=');
if (pos >= 0)
{
var argname = pairs[i].substring(0,pos);
var value = pairs[i].substring(pos+1);
QueryString.keys[QueryString.keys.length] = argname;
QueryString.values[QueryString.values.length] = value;
}
}
}
QueryString_Parse();

Normally, you take these variables with a language as PHP or JSP and d 'to act on them. Him and the moments that if you have n 'does not have access to a part of the language or simply need to treat these parameters via JavaScript. Here how.

Code:

---

var searchString = document.location.search;

// strip off the leading '?'
searchString = searchString.substring(1);

var nvPairs = searchString.split("&");

for (i = 0; i < nvPairs.length; i++)
{
    var nvPair = nvPairs[i].split("=");
    var name = nvPair[0];
    var value = nvPair[1];
}

You want to get the value from the frank parameter so you call the javascript function as follows :

var frank_param = gup( 'frank' );
