Is there a way to add a confirmation dialog when clicking an asp:button that only triggers postback if the user clicks "OK"? Here's what I have so far:
OnClientClick="if(confirm('Format the hard disk?'))
alert('something');
else alert('something else')"
The issue I'm facing is that regardless of whether "OK" or "Cancel" is clicked, the postback still occurs. How can I modify this to only trigger the postback on "OK"?
If you only want to trigger a postback after the user confirms their selection in a dialog box, you can achieve this with a more concise solution:
OnClientClick="return confirm('Are you absolutely certain?');"
Furthermore, an alternative approach is to utilize the following:
OnClientClick="return confirm('Are you sure you want to delete this item?');"
In a nutshell, the line "....; return false;" is used to prevent a click event from happening. Below is an example without using inline JavaScript:
Code:
OnClientClick="confirmAction()";
JavaScript Function:
function confirmAction()
{
var response = confirm('Are you sure you want to proceed?');
if(response == 1)
{
alert('Action confirmed');
return true; // continue with the click event
}
else if(response == 0)
{
alert('Action canceled');
return false; // stop the click event
}
}
It is essential to provide a confirm instead of just returning.

Employ the "return false" method.
When clicking the button, trigger a confirmation message asking if you want to format the hard disk. If confirmed, display an alert with 'something'. Otherwise, display an alert with 'something else' and return false.
