JQuery XSS JSONP

Published in: JavaScript 

URL: http://www.digitalscientists.com

After having trouble with xss and .getJSON() I wrote this. Solved my problems so here you go.

Plain TextExpand 
  1. $.fn.jsonp = function(params) { 
  2. 	var qs 	= '?callback='+params.callback;
  3. 	if (params.data) {          				
  4. 		for(var v in params.data) {
  5. 			qs += ('&'+v+'='+params.data[v]);
  6. 		}
  7. 	}
  8. 	var url 		= params.url+qs;  
  9. 	var time 		= new Date().getTime().toString();
  10. 	url 	   	   += ('&'+ time);             
  11. 	var tag 		= $('<script type="text/javascript" src="'+url+'" id="'+time+'">');
  12. 	var scriptTag = $(this).append(tag);
  13. 	return $(tag);
  14. }
  15. function boo(res) {
  16. 	alert('loaded!')
  17. }               
  18. $(document).ready(function(){
  19. 	params = {
  20. 		callback:'boo',
  21. 		data:{
  22. 			q:'test'
  23. 		},
  24. 		url:'http://somesite.com/jsonp'
  25. 	};
  26. 	$('body').jsonp(params);
  27. });
