A JS trouble! Urgent !!!!

Add a JS return confirm ('Are you sure you want to query?') On a Button; click "Yes" to trigger an event on the server side, and click "No" to trigger another event on the server side! That is how to get JS on the server Return value! Thank you! Urgent !!!

That ’s it. If you click No, it ’s the equivalent of canceling the click. Clicking Yes is what I really want to click. That's what it means.

ajax, xmlhttp also works

If you implement this, I can do another button. If not, the other button executes the click event, just makes it invisible.

Or do it with ajax.

if (confirm ('Are you sure you want to query?'))
{
    __doPostBack ("button1", "");
}
else
{
   __doPostBack ("button2", "");
}

button1, button2 are the ids of the two hidden buttons, and you can add a click event to these two buttons.

ajax is probably the best solution to your problem

window.returnvalue is the value returned

<script language = javascript>
function event1 ()
{
}
function event2 ()
{
}
function click ()
{
    if (confirm ('Are you sure?'))
    {
       event1 ();
    }
    else
    {
        event2 ();
    }
}
</ script>
