Jquery 返回false和e.stopImmediatePropagation似乎不起作用

我在jQuery中有以下代码。我有e.stopImmediatePropagation（）并返回false，这样代码就不会继续执行POST。如何防止代码继续

$("#saveBtn").on("click", function (e) {

       var obj = { name: $("#sName").val() };
       $.ajax({
                url: '@Url.Action("CheckExist", "PMP")',
                type: "GET",
                async: true,
                data: obj,
                success: function (data) {
                    if (data != null) {                          

                        if (data == 'True')
                        {
                            alert('HERE');                               
                            e.stopImmediatePropagation();
                            return false;
                         }

                    }
                }
        });

       // I WANT THE CODE TO NOT DO THE POST IF data == 'True' but it seems to continue regardless of return false
       $.ajax({
            type: "POST",
            url: data_appRootPath + "@Url.PMPActionUrl((object)@ViewBag.Org_ID,                 
            "GetType", null, null, null)",
            contentType: false,

您要做的是两个异步操作。这意味着这两个ajax请求同时被触发（并行）。当来自ajax请求的响应返回时，取消第二个ajax请求已经很晚了

如果希望发生这种情况，则需要在第一个请求的回调中触发第二个请求

比如说：

$("#saveBtn").on("click", function (e) {

       var obj = { name: $("#sName").val() };
       $.ajax({
                url: '@Url.Action("CheckExist", "PMP")',
                type: "GET",
                async: true,
                data: obj,
                success: function (data) {
                    if (data != null) {                          

                        if (data == 'True')
                        {
                           // I WANT THE CODE TO NOT DO THE POST IF data == 'True' but it seems to continue regardless of return false
                           $.ajax({
                                type: "POST",
                                url: data_appRootPath + "@Url.PMPActionUrl((object)@ViewBag.Org_ID,                 
                                "GetType", null, null, null)",
                                contentType: false,
                         }

                    }
                }
        });

这回答了你的问题吗？您的

CheckExist

调用是同步的-PMPActionUrl在

success:

回调运行之前运行
