How to remove close button on the jQuery UI dialog?

2698

How do I remove the close button (the X in the top-right corner) on a dialog box created by jQuery UI?

I have found this worked in the end (note the third line overriding the open function which find the button and hides it):

$("#div2").dialog({
   closeOnEscape: false,
   open: function(event, ui) { $(".ui-dialog-titlebar-close", ui.dialog | ui).hide(); }
});

To hide the close button on all dialogs you can use the following CSS too:

.ui-dialog-titlebar-close {
  visibility: hidden;
}
