jquery turn querystring into object

Question

var obj = {
 'key': 'value',
 'cheese':'bacon',
 '&':'>'
}; 
var params = $.param(obj)
console.log(params); // key=value&cheese=bacon&%26=%3E

how do I turn params back into an object? (exactly what it was before)

• tester: all of those methods help you find a single param in the string. I want a single object with keys and values of the querystring.

You could use something like this. I'm not aware of a jQuery built-in for this.

function getUrlVars() {
 if (!window.location.search) {
 return({}); // return empty object
 }
 var parms = {};
 var temp;
 var items = window.location.search.slice(1).split("&"); // remove leading ? and split
 for (var i = 0; i < items.length; i++) {
 temp = items[i].split("=");
 if (temp[0]) {
 if (temp.length < 2) {
 temp.push("");
 }
 parms[decodeURIComponent(temp[0])] = decodeURIComponent(temp[1]); 
 }
 }
 return(parms);
}

jQuery BBQ has a deparam function: https://github.com/cowboy/jquery-bbq/blob/master/jquery.ba-bbq.js line 466

• tester: sweet this ended up being the safest method. here is the snippet I took from BBQ: gist.github.com/1163405
