步驟1. 在web.config中的system.web節點里加入
<!--此節點可允許腳本跨域調用webservice-->
<webServices>
<protocols>
<add name="HttpPost"/>
<add name="HttpGet"/>
</protocols>
</webServices>
<!--此節點可允許腳本跨域調用webservice-->
步驟2. webservice代碼
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Mvc;
namespace WebService
{
/// <summary>
/// WebService1 的摘要說明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// 若要允許使用 ASP.NET AJAX 從腳本中調用此 Web 服務，請取消對下行的注釋。
[System.Web.Script.Services.ScriptService]
public class WebService1 : System.Web.Services.WebService
{
[ValidateInput(false)]
[WebMethod(Description = "測試")]
public void getDBTableInfos(string EnterpriseCode)
{
HttpContext.Current.Response.ContentType = "application/json;charset=utf-8";
string jsonCallBackFunName = string.Empty;
jsonCallBackFunName = HttpContext.Current.Request.Params["jsoncallback"].ToString();
HttpContext.Current.Response.Write(jsonCallBackFunName + "({ \"
Result\": \"" + EnterpriseCode + "\" })");
}
}
}
