Query-string encoding of a Javascript Object

Question

Do you know a fast and simple way to encode a Javascript Object into a string that I can pass via a GET Request?

No jQuery, no

A small amendment to the accepted solution by user187291:

serialize = function(obj) {
   var str = [];
   for(var p in obj){
       if (obj.hasOwnProperty(p)) {
           str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
       }
   }
   return str.join("&");
}

Checking for hasOwnProperty on the object makes JSLint/JSHint happy, and it prevents accidentally serializing methods of the object or other stuff if the object is anything but a simple dictionary. See the paragraph on for statements in this page: http://javascript.crockford.com/code.html
