var newURI = oldURI.replace(/&adidiii\=.+[&$]/, "&adidiii=" + encodeURIComponent(**WhateverThisSameFormFieldIs**) + "&")

If you just want to get a parameter from the uri do this:

function getURIParam(URI, param)
{
    var match = URI.match(new RegExp("[\?&]" + param + "=([^&]+)"));
    return match[1] ? decodeURIComponent(match[1]) : null;
}

Can you help me how to get individual ATTRIBUTE values from URI, Do we have any js methods to get the value by passing ATTRIBUTE name. "document.URL." – Oct 23 '12 at 06:54
Don't think so buddy, you're gonna have to stick with regular expressions really – Delta Oct 23 '12 at 06:58
i just tried with above code am getting this error "Cannot call method 'match' of undefined". do i need to explicitly define "match" method. am newbie in JavaScript, thanks in advance – Oct 23 '12 at 07:46

Use the following method to process the URL and return the values you are expecting out of it.

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
        vars[key] = value;
    });
    return vars;
}

If you want to get the value of adidiii use the following code.

var field = getUrlVars()["adidiii"];

alert(field);

Hope this will help you.
