JQuery attr not changing dialog title

We have this JQuery code:

$('#dialog-message'开发者_StackOverflow中文版).attr("title", t);

It works fine the first time it's executed - the title is changed. But on subsequent calls to this method the title is not updated. Any ideas?

You have to change the title of the dialog not the title attribute of the HTML Element:

$('#dialog-message').dialog( "option" , 'title' , 'new Title' )
