Get Query String from Javascript

In this tutorial you will se how to get query string values using javascript.

function getQueryString()  
{  
    var vars = [], hash;  
    var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');  
    for(var i = 0; i < hashes.length; i++)  
    {  
        hash = hashes[i].split('=');  
        vars.push(hash[0]);  
        vars[hash[0]] = hash[1];  
    }  
    return vars;  
}  

Let's suppose we have the following URL
http://www.mysite/home.aspx?id=1&name=test
Calling getQueryString() function would return you the following array:

{  
    "id"    : "1",  
    "name" : "test"  
}

To get the value of parameters you will do this.

var id= getQueryString()["id"];  
var name= getQueryString()["name"];  

Hope this tutorial will help you.

Convert in Uppercae and Lowercase using JavaScript

you can use builtIn javascript .toUpper() and .toLower() functions to convert string into upper or lower case.

var test="This is Test";

var test="This is Test";

var test=test.toLowerCase();
