JSON函数无法在Asp.net C＃

Question

当我调用JSON加载webmethod静态事件时，那个事件没有加载[我通过调试模式看到]通过单击Asp.net C＃中的提交按钮。在整个表单的位置，即整个网页正在加载。但我不想加载整个网页。

这是我的代码

这是客户端代码

<input type="submit" id="btn_save" value="Save" class="button" />

$(function () {
            $(document).on("click", "#btn_save", function (e) {
                $.ajax({
                    type: "POST",
                    url: "schoolregistration.aspx/EntrySave",
                    data: JSON.stringify({ name: $('#txt_schoolname').val() }),
                    success: function (msg) {
                        if (msg.d) {
                            alert("Successfully Added School Registration...!!!");
                            return false;
                        }
                    },
                    failure: function () {
                        alert("Error! Try again...");
                    }
                });
            });
        });

这是服务器端代码

[WebMethod]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public static void EntrySave(string schoolName)
    {
         //here is the code
    }
