推荐答案

以下内容将防止将来所有将来的AJAX请求被缓存，无论您使用哪种jQuery方法($ .get，$. ajax等)

The following will prevent all future AJAX requests from being cached, regardless of which jQuery method you use ($.get, $.ajax, etc.)

$(document).ready(function() {
  $.ajaxSetup({ cache: false });
});

您应该使用$ .ajax，这将允许您关闭该实例的缓存:

you should use $.ajax, which will allow you to turn caching off for that instance:

$.ajax({url: "myurl", success: myCallback, cache: false});
