jquery调用asp.net的WebService

asmx.cs

using System.Web.Script.Services;



[System.Web.Script.Services.ScriptService]
public class test : System.Web.Services.WebService

{

       [ScriptMethod(UseHttpGet = true)]

public void testMethod(int id)
        {
        }

}

js

$.ajax({
    url: 'test.asmx/testMethod',
    dataType: "json",
    data: "id=2",
    beforeSend: function(x) {
        x.setRequestHeader("Content-Type", "application/json; charset=utf-8");
    },
    success: function(json) {
        var o = eval("(" + json.d + ")");
        callBack(o);
    }
});

 

或者向下面这样直接使用也行，原因暂时不明

 

        $.ajax({
            type: "POST",
            url: "/test.asmx/testMethod",
            data: {
                htmlStr: "<font color='red'>你好</font>",
                Co: 877,
                Tablename: "table_2",
                buttonId: 96
            },
            success: function () {
                alert("success");
            },
            error: function () {
            }
        });
