ASP.NET下Ajax局部刷新简单应用-优快云博客

实现功能：单击按钮，将从数据库获取的数据返回给文本框1(刷新文本框1)，而文本框2不刷新

页面1：test.html

<script language=javascript>
function getData()
{
var xh = new ActiveXObject("Microsoft.XMLHTTP")
xh.open("get","test.aspx",false);
xh.send();
if(xh.readyState == 4 && xh.status == 200)
{
document.getElementById("tb1").innerText= xh.responseText;
}
}
</script>
</head>
<body>
<input id="tb1" type="text"/><button οnclick="getData()">点击</button>
<br/>
<input id="tb2" type="text" />
</body>
</html>

页面2主要代码：test.aspx

     protected void Page_Load(object sender, EventArgs e)
    {
      //数据库操作代码
      ......

     //把从数据库取出的数据用Response.Write返回
     Response.Write("我是后台获取的数据");
    }
