You can use the WebMethods to call server side function (C#) from ClientSide(Javascript)
Please try the below implementation
1) Add a script Manager to your page and set the 'EnablePageMethods' property of script manager to True.
<asp:ScriptManager ID="ScriptManager2" runat="server" EnablePageMethods="true"/>
2) Modify your C# Method like given below
//Please note that the method should be a Static and WebMethod.
[System.Web.Services.WebMethod]
public static void YourMethodName()
{
//Your Logic comes here
}
3) Modify your javascript code like given below
function completed() {
//Call the Delete Method
PageMethods.YourMethodName();
//Change the url here
window.location = "http://www.asp.net";
}
Modified Code :
<!DOCTYPE html>
<html>
<head>
<script>
function startCountdown(timeLeft) {
var interval = setInterval(countdown, 1000);
update();
function countdown() {
if (--timeLeft > 0) {
update();
} else {
clearInterval(interval);
update();
//Show the alert message , change the message as per your need
alert('Time Up!');
completed();
}
}
function update() {
hours = Math.floor(timeLeft / 3600);
minutes = Math.floor((timeLeft % 3600) / 60);
seconds = timeLeft % 60;
document.getElementById('time-left').innerHTML = '' + hours + ':' + minutes + ':' + seconds;
}
function completed() {
//Call the Delete Method
PageMethods.YourMethodName();
//Change the url here
window.location = "http://www.asp.net";
}
}
</script>
</head>
<body onload="startCountdown(20);">
<form runat="server">
<asp:ScriptManager ID="ScriptManager2" runat="server" EnablePageMethods="true" />
Redirect in <span id="time-left"></span>
</form>
</body>
