How to get querystring value from url using - JS - jquery

Problem definition

http://www.raymn.in/index.php?username=rahul&password=123

In above link querystring is username=rahul&password=123 and the values are rahul and 123.

So we have to extract values from url. how??

Solution

Step by Step description,
First Step: Get querystring from URL.. var sPageURL = window.location.search.substring(1);

var sPageURL holds "username=rahul&password=123"

Second Step: Split queries from "&".. var sURLVariables = sPageURL.split('&');

sURLVariables is array of "username=rahul" and "password=123"

Third Step: Split values from "="..var sParameterName = sURLVariables[i].split('=');

sParameterName holds array of "username", "rahul", "password", "123"

Example
//JS example
function getQueryStringParams(sParam)
{
    var sPageURL = window.location.search.substring(1);
    var sURLVariables = sPageURL.split('&');
    for (var i = 0; i < sURLVariables.length; i++) 
    {
        var sParameterName = sURLVariables[i].split('=');
        if (sParameterName[0] == sParam) 
        {
            return sParameterName[1];
        }
    }
}​

//JQuery example
// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
    var array = [], values;
    var arrayOfQuery = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
    for(var i = 0; i < arrayOfQuery.length; i++)
    {
        values = arrayOfQuery[i].split('=');
        values.push(values[0]);
        vars[values[0]] = values[1];
    }
    return array;
}

How to create a redirect page using JS/JQUERY

Problem definition

I am owner of two domains and want to redirect my traffic from one website to another,

http://www.raymn.in drive traffic to http://www.raymn.com.

Previous JQuery posts and related terms, Create redirect page form js/jquery, Modify URL without reloading

Solution

The window.location object can be used to get the current page address (URL) and to redirect the browser to a new page.

OR 

You can use window.location.replace(URL).

The difference between window.location and window window.location.replace(URL), is that replace() removes the URL of the current document from the document history, meaning that it is not possible to use the "back" button to navigate back to the original document.

Example

window.location = "http://www.raymn.com";

OR

window.location.replace("http://www.raymn.com");
