现在，通过在ajax请求中启用/禁用缓存选项很容易做到这一点，就像这样

$(function () {
    var url = 'your url goes here';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
                cache: true, //cache enabled, false to reverse
                complete: doSomething
            });
        });
    });
    //ToDo after ajax call finishes
    function doSomething(data) {
        console.log(data);
    }
});

基本上只需要添加cache:false;在ajax中，你认为内容会随着进程的进行而改变。在内容不会改变的地方，你可以省略这个。这样你每次都会得到新的响应

如果你正在使用。net ASP MVC，通过在end point函数上添加以下属性禁用控制器动作上的缓存:

[OutputCacheAttribute(VaryByParam = "*", Duration = 0, NoStore = true)]

下面的代码将阻止所有将来的AJAX请求被缓存，无论您使用的是哪种jQuery方法($。,美元。ajax,等等)。

$.ajaxSetup({ cache: false });

The real question is why you need this to not be cached. If it should not be cached because it changes all the time, the server should specify to not cache the resource. If it just changes sometimes (because one of the resources it depends on can change), and if the client code has a way of knowing about it, it can append a dummy parameter to the url that is computed from some hash or last modified date of those resources (that's what we do in Microsoft Ajax script resources so they can be cached forever but new versions can still be served as they appear). If the client can't know of changes, the correct way should be for the server to handle HEAD requests properly and tell the client whether to use the cached version or not. Seems to me like appending a random parameter or telling from the client to never cache is wrong because cacheability is a property of the server resource, and so should be decided server-side. Another question to ask oneself is should this resource really be served through GET or should it go through POST? That is a question of semantics, but it also has security implications (there are attacks that work only if the server allows for GET). POST will not get cached.

你可以使用缓存属性:

$.ajax({
    method: "GET",
    url: "/Home/AddProduct?",
    data: { param1: value1, param2: value2},
    cache: false,
    success: function (result) {
        // TODO
    }
});
