Pass dialog title variable in jQuery Dialog

I need to pass the title of the jQuery dialog variably.

I am trying to use the "data" property like this:

jQuery( "#dialog" ).data( 'the_title', 'John Doe Dialog' ).dialog( "open" );
    
jQuery( function() {

    jQuery( "#dialog" ).dialog({       

        title: jQuery( "#dialog" ).data( 'the_title' ), 

    });

});

But it is not working, it is displaying the default title.

Any thought please?

>Solution :

You can directly specify any of the dialogue options documented here,
title being one such, I’ve added another couple of options as further examples.

jQuery( "#dialog" ).dialog({
    title: 'John Doe Dialog',
    width: '100px',
    height: '50px'
});

You can also specify any option after the dialog is created

$('#dialog').dialog();
$('#dialog').dialog('option', 'title', 'wibble');

hence you can use this chaining style of code:

$('#dialog').dialog().dialog('option', 'title', 'wibble');
