jQuery Mobile Page overlayTheme Option

Last Updated : 20 Jan, 2022

jQuery Mobile is an HTML5 based user interface system designed to make responsive websites and apps that are accessible on all smartphone, tablet, and desktop devices.

Page is a widget in jQuery Mobile to display single or multiple linked components within the HTML document. It is responsible for maintaining a single item in jQuery Mobile’s framework.

In this article, we are going to learn the jQuery Mobile Page overlayTheme option. The overlayTheme option is used for the dialog widgets appearing over the page. The dialogs appear over a layer which by default has the theme of “a” but can be changed.

Syntax: The overlayTheme option takes a single character from a-z where each character depicts a color. The default value is ‘a’.

$("#dialogPage").page({
    overlayTheme: "b",
});

Get the overlayTheme option:

var overlayTheme = $("#dialogPage").page( "option", "overlayTheme" );

Set the overlayTheme option:

$("#dialogPage").page( "option", "overlayTheme", "b" );
