What is the best way to eliminate a class from a jQuery UI Dialog?

Can a specific class be removed from the jQuery UI dialog?

http://api.jqueryui.com/dialog/#option-dialogClass

I'm curious if there is a way to remove a particular class from the dialog. Thank you.

Answer №1

To change the class, simply replace the existing option

// Get the current class string
var dlgClass = $( ".selector" ).dialog("option", "dialogClass");

// remove the unwanted class
dlgClass.replace("delete-this-class", "");

// update the dialog class
$(".selector").dialog("option", "dialogClass", dlgClass);

You could also use split(" ") or Regex to adjust the class value accordingly.

Modification:

I tried using removeClass, but it seems that the widget tracks separately added classes. This method does not seem to function correctly:

$( "#dialog" ).dialog({ autoOpen: false, dialogClass: "foo bar" });
...
$("#dialog").closest(".ui-dialog").removeClass("foo");
var dialogClass = $("#dialog").dialog("option", "dialogClass");
console.log(dialogClass);  // foo bar

Nevertheless, relying on the widget's DOM structure in this manner may not be ideal.
