问题描述
大家好,
我对jQuery非常陌生,并尝试使用jQuery.ajax做简单的例子
但这每次都向我显示以下消息
"Microsoft JScript运行时错误:"myMethod"未定义"
请指导我缺少的地方.
我有以下HTML代码.
Hello Everyone,
I am very new to jQuery and trying to do simple examples using jQuery.ajax
but every time this is showing me the following message
"Microsoft JScript runtime error: ''myMethod'' is undefined"
Please guide me where I am lacking.
I have the following HTML code.
<input type="button" onclick="callServer()" value="Test Button" />
<asp:Label ID="lblTest" runat="server">
服务器端代码
the server side code
[WebMethod]
public void myMethod()
{
lblTest.Text = DateTime.Now.ToString();
}
jQuery代码
the jQuery code
function callServer() {
$.ajax(
{
url: "~/jQuery.aspx.cs/"+myMethod,
contenType:"application/json; charset=utf-8",
dataType :"json",
success:onSuccess,
fail:onFail
});
}
function onSuccess() {
alert("Success!!");
}
function onFail() {
alert("Failed!!");
}
推荐答案
.ajax( { 网址:〜/jQuery.aspx.cs/" + myMethod, contenType:"application/json; charset = utf-8", dataType:"json", 成功:成功, 失败:失败 }); } 函数onSuccess(){ alert(成功!"); } 函数onFail(){ alert(失败!"); }
.ajax( { url: "~/jQuery.aspx.cs/"+myMethod, contenType:"application/json; charset=utf-8", dataType :"json", success:onSuccess, fail:onFail }); } function onSuccess() { alert("Success!!"); } function onFail() { alert("Failed!!"); }
