window.setTimeout with confirmation message function

[fototex]

Hi friends,

I am trying to use the window.setTimeout feature so that a message pop-up with yes/no appears on the screen asking whether to extend the session.

*If yes is clicked, the current page reloads.
*If no is clicked, nothing happens. (the session will expire anyway).

Could not figure out the code.
Sorry if it had been post before.

confirm returns true or false, if OK is clicked, true, otherwise false. When testing for true or false, you don't even need an '==true', just

if (condition) {
// true
}

So

function reloadPage(url) {
var ok = confirm('Extend session?');
if (ok) { document.location=url; }
return false;
}

should do it. Put that in a document with this to test.

<p><a href="some-file.html" onclick="return reloadPage(this.href);">test</a></p>

why not be fancy...

<a href="some-file.html" onclick="return confirm('Extend session?');">test</a>

I have used the following code:

window.setTimeout("if (confirm('continue session?')){window.reload}",5000) ;

The code pops up the confirmation message but after confirming the message, nothing happens. The page does not reload itself.

Any advises appreciated.

@fototex, you have the setTimeout in the wrong place (note also that you don't need the 'window' portion):

if (confirm('continue session?')) {
  setTimeout(window.reload, 5000);
}

if you wanted this to appear sometime after the page loaded:

setTimeout(function () {
  if (confirm('continue session?')) {
    setTimeout(window.reload, 5000);
  } 
}, 1000 * 60 * 9); 

That will give you the confirm dialog 9 minutes after the page loads, and if the user clicks Yes, will reload the page 5 seconds later.

Also note, avoid using the quoted string version of setTimeout. That is, instead of this:

setTimeout("somefunction()", 1000);

pass in a function reference instead:

setTimeout(somefunction, 1000);
