在 asp.net 中不使用 ScriptManager 从 JavaScript 调用 WebServices

Question

我为我的 Asp.net 项目创建了一个 Web 服务。目前，我通过引用ScriptManager 中的服务从 JavaScript 访问服务。但我不想添加ScriptManager 以便可以在任何 HTML 页面中使用它。

好的。所以你想对一些 web 服务方法进行 ajax 调用并将参数传递给它。并且你要以 JSON 格式传递参数

function CallWebServiceMethod() {
     var requestedData = "{ 'LifeCycleN': '" + var_LifeCycleN +//var_LifeCycleN some var represent your data that you want to send
            "', 'LiOrder': '" + var_LiOrder +//var_LiOrder again some var represent your data that you want to send
            "'}";
    $.ajax({
        type: "POST",
        url: "Services/YouWebServiceName.asmx/WebServiceMethodName",
        data: requestedData,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (msg) {// I 'll assume that your web-service 'll return bool value indicate if the operation done successfully or not.
        //do here what you want to do is the request was successful.
        }
    });

    }
