Prevent browser caching of AJAX call result
The following will prevent all future AJAX requests from being cached, regardless of which jQuery method you use ($.get, $.ajax, etc.)
$.ajaxSetup({ cache: false });
JQuery's $.get() will cache the results. Instead of
$.get("myurl", myCallback)you should use $.ajax, which will allow you to turn caching off:
$.ajax({url: "myurl", success: myCallback, cache: false});
I use new Date().getTime(), which will avoid collisions unless you have multiple requests happening within the same millisecond:
$.get('/getdata?_=' + new Date().getTime(), function(data) { console.log(data); });Edit: This answer is several years old. It still works (hence I haven't deleted it), but there are better/cleaner ways of achieving this now. My preference is for this method, but this answer is also useful if you want to disable caching for every request during the lifetime of a page.
