call code behind from javascript timer 1

codecomm · Jul 24, 2007

I've had a lot of help with some session timeout issues from other postings. Thank you to all who have responded and given input. Everything is helpful!

What I'd like to do is have a time via javascript that calls an Update/Save routine at 19 minutes of inactivity.

We've left our Session timeout value to 20 minutes, and it's been asked if we can simply save/update data automatically, so if the user session times out in another minute, they haven't lost any data entry.

I know how to show a client side pop-up warning at 15 minutes, but haven't figured out how to make the client side javascript call something in code behind.

Thanks!

Just use the javascript to submit the form.

document.forms[0].submit();

I'm trying the following and get a javascript error about the myHiddenButtonID is not defined:

*****

HTML

******

</head>



<body onmousedown = "window_activity()" onkeypress="window_activity()">

<script type="text/javascript">

var timerPROMPT = 0;

var timerCLOSE = 0;

function EndApp(){

//RateDeck.style.display = "none"

//spDeck.style.display = "none"

}

function StopTiming(){

if(timerPROMPT > 0)

window.clearTimeout(timerPROMPT)

//call button

var myHiddenButton = document.getElementById(myHiddenButtonID);

myHiddenButton.Click()

//end button call

if (confirm('Due to inactivity, your session is about to time out.')== 1)

{

if(timerCLOSE > 0)

window.clearTimeout(timerCLOSE)

timerPROMPT = window.setTimeout("StopTiming()",5000);

timerCLOSE = window.setTimeout("EndApp()",8000);

}

else

{

EndApp();

}

}

function window_activity() {

if(timerPROMPT > 0)

window.clearTimeout(timerPROMPT)

if(timerCLOSE > 0)

window.clearTimeout(timerCLOSE)

timerPROMPT = window.setTimeout("StopTiming()",5000);

timerCLOSE = window.setTimeout("EndApp()",6000);

}

</script>



<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server" />

<div>

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

<asp:Button ID="myHiddenButtonID" runat="server" Font-Size="XX-Small" OnClick="myHiddenButtonID_Click"

Text="Hide" /><br />

<br />

<br />

<asp:Image ID="Image1" runat="server" ImageUrl="~/images/top.jpg" />

</div>

</form>

</body>

</html>

*****

Code behind

****

protected void myHiddenButtonID_Click(object sender, EventArgs e)

{

Response.Write("Hidden button click event!");

}

Try asking in the javascript forum for any javascript issues you have. They will also want to see your client-side rendered HTML, not your ASP.NET code.

So, just changed the javascript to:

//call button

var myHiddenButton = document.getElementById("myHiddenButtonID");

myHiddenButton.OnClick();

//end button call

..and tried:

myHiddenButton.Click();

..and now I get the object doesn't support this proptery or method in a javascript error
