difference between xmlhttprequest and $.ajax(), $.load
jquery
Solution
XMLHttpRequest is the raw ajax request object. Working with this directly would be the 'lightest', but you're losing all the cross browser compatibility provided by the $.ajax() method in JQuery. If you want your code to work across all browsers, you must use $.ajax().
Problem
what is actually difference between xmlhttprequest and $.ajax() i want to know which is the lightest function from above to load data....
