Menu
I am trying to prevent users from inadvertently using the back button to access previous panels in an asp.net form.
The form is a single page which appears to be multiple pages.
If the user presses the browser back button I would like a confirm alert to appear giving the user the option to procede.
The javascript function I am using is fired by the OnUnload event.
<code>
function UnLoadConfirm() {
return confirm(‘Using the back button will clear the form!’);
// if yes button is clicked proceed to previous page
//else do nothing
}
</code>
