Question

Is there any way to check with jQuery for POST within the URL similar to the PHP way?

PHP version:

if(!empty($_GET)) { // do stuff }

---

Sorry. I mean GET not POST.

I’m looking to fetch the URL on the page load $(document).ready( function() { // here });

Example URL: http://www.domain.com?a=1

And than past value of the var a into the function OnLoad();

extend jquery to get the url vars

$.extend({
  getUrlVars: function(){
    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;
  },
  getUrlVar: function(name){
    return $.getUrlVars()[name];
  }
});

then you can call

if($.getUrlVars().length > 0){ // do something }

you can also query a specific value by

if($.getUrlVar('name') == 'frank'){
