步骤1. 在web.config中的system.web节点里加入
- <!--此节点可允许脚本跨域调用webservice-->
- <webServices>
- <protocols>
- <add name="HttpPost"/>
- <add name="HttpGet"/>
- </protocols>
- </webServices>
- <!--此节点可允许脚本跨域调用webservice-->
步骤2. webservice代码
- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Web;
- using System.Web.Services;
- using System.Web.Mvc;
- namespace WebService
- {
- /// <summary>
- /// WebService1 的摘要说明
- /// </summary>
- [WebService(Namespace = "http://tempuri.org/")]
- [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
- [System.ComponentModel.ToolboxItem(false)]
- // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务,请取消对下行的注释。
- [System.Web.Script.Services.ScriptService]
- public class WebService1 : System.Web.Services.WebService
- {
- [ValidateInput(false)]
- [WebMethod(Description = "测试")]
- 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 + "\" })");
- }
- }
- }
步骤3. html页面部分
- <!DOCTYPE html>
- <html>
- <head>
- <title>Index</title>
- <script src="http://www.cnblogs.com/Scripts/jquery-1.5.1.js" type="text/javascript"></script>
- <script type="text/javascript">
- $(function () {
- $("#btnSubmit").click(function () {
- var EnterpriseCode = "39"; //企业代码
- var dataStr = "EnterpriseCode=" + EnterpriseCode;
- $.ajax({
- type: "get",
- url: "http://xxx/xxx.asmx/AntiWebQuery_Ajax?jsoncallback?",
- dataType: "jsonp",
- jsonp: 'jsoncallback',
- data: dataStr,
- success: function (result) {
- //返回结果
- alert(result.Result);
- }
- });
- });
- });
- </script>
- </head>
- <body>
- <div>
- <input id="btnSubmit" type="button" value="查询" />
- </div>
- </body>
- </html>
