无法在浏览器中手动访问ASMX Web服务，但它可以使用jQuery(Can't access ASMX web service manually in browser but it works using jQuery)

 我是JQuery和Web Services的新手。 我的问题是（在下面的代码中），为什么url：“WebService1.asmx / WebMethod”通过这个JQuery代码工作，但如果我直接在浏览器中输入该URL，它说无法找到路径？ 我必须在浏览器中手动单击服务的“调用”按钮才能调用该方法，然后导航到WebService1.asmx / WebMethod。 
 
 $(document).ready(function () {
        $.ajax({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: "WebService1.asmx/WebMethod",
            data: "{}",
            dataType: "json",
            success: function (msg) {
                alert(msg.d);
            },
            error: function (errormessage) {
                alert("got an error");
            }
        });
    });

I'm new to JQuery and Web Services. My question is (in the following code), why does url: "WebService1.asmx/WebMethod" work through this JQuery code but if I type that URL directly in my browser, it says the path cannot be found? I have to manually click on the "Invoke" button for the service in the browser in order to call the method and then it navigates to WebService1.asmx/WebMethod.
 
 $(document).ready(function () {
        $.ajax({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: "WebService1.asmx/WebMethod",
            data: "{}",
            dataType: "json",
            success: function (msg) {
                alert(msg.d);
            },
            error: function (errormessage) {
                alert("got an error");
            }
        });
    });
