问题描述
如何使用PageMethods从静态方法中访问控件并设置aspx页面中存在的控件的属性。
例如：
How can i access the controls and set the properties of the controls, that are present in the aspx page, inside the static method which is called from javascript using PageMethods.
for eg:
<html>
<head>
<script type="text/javascrip">
var timer;
function chk_me()
{
clearTimeout(timer);
timer = setTimeout(function validate()
{
var name = document.getElementById(<%=txtname.ClientID>).value;
var address = document.getElementById(<%=txtaddress.ClientID>).value;
PageMethods.ProcessIT(name, address, onSucess, onError);
function onSucess(result) {
alert(result);
}
function onError(result) {
alert("Something wrong.");
}
}, 2000);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID='ScriptManager1' runat='server' EnablePageMethods='true' />
<asp:TextBox ID="txtname" runat="server"></asp:TextBox>
<asp:TextBox ID="txtaddress" runat="server"></asp:TextBox>
<asp:TextBox ID="txt_1" runat="server" onkeyup="chk_me()"></asp:TextBox>
</form>
</body>
</html>
