一、Jquery向aspx页面请求数据
前台页面JS代码：
代码如下:
$(“#Button1”).bind(“click”, function () {
$.ajax({
type: “post”,
url: “default.aspx”,
data: “name=” + $(“#Text1”).val(),
success: function (result) {
alert(result.msg);
}
});
});
代码如下:
<input id=”Text1″ type=”text” value=’张三’/>
<input id=”Button1″ type=”button” value=”提交” />
后台cs代码：
代码如下:
protected void Page_Load(object sender, EventArgs e)
{
if (Request[“name”]!=null)
{
Response.ContentType = “text/json”;
Response.Write(“{\”msg\”:\””+Request[“name”]+”\”}”);//将数据拼凑为Json
Response.End();
}
}
二、Jquery向WebService页面请求数据
代码如下:
$(“#Button2”).bind(“click”, function () {
$.ajax({
type: “post”,
contentType: “application/json”,
url: “WebService.asmx/HelloWorld”,
data: “{name:'” + $(“#Text1”).val() + “‘}”,
datatype: “json”,
success: function (result) {
alert(result.d);
}
});
});
<input id=”Button2″ type=”button” value=”向WebService提交” />
WebService代码
代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
/// <summary>
/// Summary description for WebService
/// </summary>
[WebService(Namespace = “http://tempuri.org/”)]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.

public class WebService : System.Web.Services.WebService {
public WebService () {
//Uncomment the following line if using designed components
