利用ajax可以在javascrip和.net里的cs文件中实现方法交互,ajax是不分语言的
1.test.aspx
<script language="javascript">
if(!window.XMLHttpRequest)
window.XMLHttpRequest = function()
{
return new ActiveXObject("Microsoft.XMLHTTP");
};
function test(){
var xmlHttp = new XMLHttpRequest();
xmlHttp.open("post", "ajax.aspx?name="+document.getElementById("txtname").value+"&pwd="+document.getElementById("txtpwd").value+"&t=" + Math.random(), true);
xmlHttp.onreadystatechange=function(){
if(xmlHttp.readyState==4){
alert(xmlHttp.responseText);
}
}
xmlHttp.send("");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="txtname" type="text" />
<input id="txtpwd" type="text" />
<input type="button" onclick="test()" value="test ajax"/>
</div>
</form>
</body>
</html>
2.ajax.aspx.cs
public partial class ajax : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string name = Request.QueryString["name"];
string pwd = Request.QueryString["pwd"];
Response.Write(Login(name,pwd));
}
protected string Login(string name, string pwd)
{
if (name == "LJK" && pwd == "123")
{
return "true";
}
else
{
return "修改成功";
}
}
}
