[英]Jquery AJAX with ASP.NET WebMethod Returning Entire Page
I'm doing some simple tests (in preparation for a larger project) to call an ASP.NET WebMethod using JQuery AJAX. 我正在做一些简单的测试(准备一个更大的项目)来使用JQuery AJAX调用ASP.NET WebMethod。 In my example, my WebMethod returns a simple string.
在我的示例中,我的WebMethod返回一个简单的字符串。 However, when I attempt to call it using JQuery, I get the entire HTML page content returned instead of just my string.
但是,当我尝试使用JQuery调用它时,我会返回整个HTML页面内容,而不仅仅是我的字符串。 What am I missing?
我错过了什么?
Client Side : 客户端 :
$(document).ready(function ready() {
$("#MyButton").click(function clicked(e) {
$.post("Default.aspx/TestMethod",
{name:"Bob"},
function(msg) {
alert("Data Recieved: " + msg);
},
"html"
);
});
});
Server Side: 服务器端:
using System;
using System.Web.Services;
namespace JqueryAjaxText
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
[WebMethod]
public static string TestMethod(string name)
{
return "The value submitted was " + name;
}
}
}

Read through the article but its essentially: 仔细阅读文章,但基本上:
$("#Result").click(function() {
$.ajax({
type: "POST",
url: "Default.aspx/GetDate",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
$("#Result").text(msg.d);
}
});
});
I think I was getting confused with the "type" parameter in JQuery's $.post command. 我想我对JQuery的$ .post命令中的“type”参数感到困惑。 After talking to some folks, it seems that the return type for calling a WebMethod MUST be "json".
在与一些人交谈之后,似乎调用WebMethod的返回类型必须是“json”。 I was trying to use "html".
我试图使用“html”。 Once I changed it to "json" and then everything worked like normal.
一旦我将其改为“json”,然后一切正常。 So apparently, a method decorated with [WebMethod] returns JSON only, and that's where my hangup was.
显然,用[WebMethod]修饰的方法只返回JSON,这就是我的挂机所在。
Thanks for your replies guys. 谢谢你们的回复。
Try changing the last parameter "html" to "text". 尝试将最后一个参数“html”更改为“text”。 This parameter specifies the type of data to be returned.
此参数指定要返回的数据类型。
I had the exactly the same problem: WebMethod returned the entire HTML page instead the intended data. 我有完全相同的问题:WebMethod返回整个HTML页面而不是预期的数据。 For me, the solution came from changing inside ~/App_Start/RouteConfig.cs the following line:
对我来说,解决方案来自于更改〜/ App_Start / RouteConfig.cs内部的以下行:
settings.AutoRedirectMode = RedirectMode.Permanent;
to 至
settings.AutoRedirectMode = RedirectMode.Off;
