How to get values from the URL using javascript?

Java Scripts, Uncategorized

When we are in need to get values from the URL using java script as we get them using $_REQUEST[‘name’]; in PHP, $q->param(‘name’); in Perl etc. we can use the following function to get the values in java script :

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

To get the values we should call the above function as follows :

var val1=getUrlVars()["name1"];
alert(val1);

If the URL is http://ww.example.com/page.php?name1=value1&name2=value2&name3=value3, then the

var val1=getUrlVars()["name1"]; //value1
var val2=getUrlVars()["name2"]; //value2
var val2=getUrlVars()["name2"]; //value3
