If you’re using jQuery UI Dialog, you know sometimes there’s a need to access dialog’s button objects after the dialog has already been created. This can be easily done via

$(dialogElement).dialog("option").buttons

command. One possible scenario where this can be useful – is executing specific button click function when user clicks [X] in dialog title. Imagine that buttons are set via array and the last object in this array is always something like CANCEL or NO or DISREGARD – and you want to simulate click of that last button whenever user clicks [X]. Using above command it’s pretty straightforward:

$(oDivDialog).dialog({
   //... some dialog parameters
   buttons: arrayOfButtonObjects,
   //... some more parameters
   close: function () {
      var buttons = $(this).dialog("option").buttons;
      buttons[buttons.length - 1].click();
   }
})

Line 5 begins close event which is called on dialog closing.
Line 6 retrieves array of buttons for the dialog
Line 7 calls click() function of the last button in the array
