Question

尝试从jquery中使用简单的WCF服务时遇到了一些特殊问题。请参阅以下代码：

$(document).ready(function () { // Initialize the carousel on the header part of the page $("#myCarousel").carousel({ interval: 2000 });



// The handler for the submit button (login form)
$("#submit").click(function () {
    var sendData = '{"username": "' + 
                     $("#usernameTB").val() + 
                   '", "password": "' + 
                     CryptoJS.MD5($("#passwordTB").val()) + 
                   '"}';

    $.ajax("Services/LoginUser.svc/Login", {
        cache: false,
        type: "POST",
        data: sendData,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        processData: true,
        complete: ServiceCompleted
    });
});

// The handler for the submit button (login form) $("#submit").click(function () { var sendData = '{"username": "' + $("#usernameTB").val() + '", "password": "' + CryptoJS.MD5($("#passwordTB").val()) + '"}'; $.ajax("Services/LoginUser.svc/Login", { cache: false, type: "POST", data: sendData, contentType: "application/json; charset=utf-8", dataType: "json", processData: true, complete: ServiceCompleted }); });

当我在IE中使用此代码时，它就像一个魅力，即执行调用并返回我期望的内容，请参阅下面的请求/响应的fiddler转储：

{"d":null}

如果我使用Chrome执行相同操作，则会收到以下请求/响应转储：

{"d":null}

现在，警报没有显示{{d“：null}文本。

有谁知道阻止我使用responseText的区别是什么？

我在谷歌搜索后找到解决问题的方法......

似乎我的表单上的提交按钮的单击处理程序必须返回false才能使其正常工作。

我不知道为什么，但它有效...

来自$ .ajax的wcf调用在chrome中不起作用
