JQuery实现异步刷新(原创)
JQuery,是轻量级的js库,把繁琐的js代码封装,使调用更简单,完成更多功能。同样,封装了js利用XMLHttpRequest实现的异步刷新.今天很简单介绍这一封装的调用
示例如下:
调用页面:JqueryTest.aspx(注:后台无代码)
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="JqueryTest.aspx.cs" Inherits="XmlHttpRequestTest.JqueryTest" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
<script src="JS/jquery-1.4.2.js" type="text/javascript"></script>
<script language="javascript">
function test() {
$.ajax({
type: "POST",
url: "JqueryService.aspx",
data: "userName=123&password=456" ,
success: function(data) {
if (data == "true") {
alert("登陆成功!");
}
else {
alert("登陆失败");
}
}
});
}
function btntestajax_onclick() {
test();
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="btntestajax" type="button" value="测试异步刷新" onclick="return btntestajax_onclick()" /></div>
</form>
</body>
</html>
被调用界面:JqueryService
前台:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="JqueryService.aspx.cs" Inherits="XmlHttpRequestTest.JqueryService" %>
后台:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace XmlHttpRequestTest
{
public partial class JqueryService : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
String userName=Request.Form["userName"].ToString();
String password=Request.Form["password"].ToString();
if (userName.Equals("123") && password.Equals("456"))
{
Response.Write("true");
}
else
{
Response.Write("false");
}
}
}
}
