Question

我使用HTML5 / Javascript / JqueryAjax创建了基于Web的应用程序。托管网址工作正常，但是当我使用phonegap 2.8.1在Windows Phone 7中运行它时，它无法运行。它调用错误函数。

这是我的代码：

<!DOCTYPE html>

我真的不知道是什么问题。它适用于Android，但不适用于Windows手机。任何帮助将不胜感激。

问题已解决!!!!

我必须在$.support.cors = true;来电之前添加$.ajax。问题是我是从跨平台向WebService发布信息。

以下是代码：

$.support.cors = true;
    $.ajax({
                    type: "POST",
                    url: create_user,
                    data: JSON.stringify(make),
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function (result) {
                        window.location = "Login.html";
                    },
                    error: function (error) {
                        $("#alert").show();
                        document.getElementById('alert').innerHTML = "<b>Connection Failed!</b> Please Check Your Configurations";
                    }
                });

如果这不是好的做法，我不会，但它帮助了我。玩得开心。
