How to find out which button was pressed on a Dialog2?

[Dirk Eyfrig]

I've implemented the last example (A warning message) provided on the Dialog2 documentation page.

So far, so nice.

But an action should only happen when the user pressed the "Delete the thing" button, but not when pressing the "Cancel" button.

But how do I find out which button a user pressed?

OK, I found the solution myself.

From the example, you have to replace 

AJS.$(document).on("click", "#demo-warning-dialog button", function (e) {
    e.preventDefault();
    AJS.dialog2("#demo-warning-dialog").hide();
})

by separate handlers for the two buttons

AJS.$(document).on('click', '#warning-dialog-confirm', function (e) {
    e.preventDefault()
    AJS.dialog2('#demo-warning-dialog').hide()
// code that needs to be run when action is confirmed
    alert('action confirmed')
})

AJS.$(document).on('click', '#warning-dialog-cancel', function (e) {
    e.preventDefault()
    AJS.dialog2('#demo-warning-dialog').hide()
})

Or is there a more elegant solution?

If not, the above code might be added to the documentation page.
