Append string to jquery-ui-dialog title -

so need know how can append string dialog title.

for example string foo.

and if run

$(function () {     $("#dialogid").dialog({})     $("#dialogid").dialog('option', 'title', 'bar');      setinterval(function(){           var title123 = $("#dialogid").dialog( "option", "title" );         var n = title123.indexof("foo");         if(n < 0) {             $("#dialogid").dialog( "option", "title", "foo" + title123);         }      }, 10); });
