jQuery Mobile Dialog initSelector Option

Last Updated : 14 May, 2022

jQuery Mobile is a web-based technology used to make responsive content that can be accessed on all smartphones, tablets, and desktops.

In this article, we will be using the jQuery Mobile Dialog initSelector option. The value of this option is a selector string that picks elements on the basis of the value of this option and explicates the stated Dialog widgets on every element of the following list.

Syntax:

Initializing the Dialog with the initSelector option.

$( ".selector" ).dialog({
     initSelector: "div.custom"
});

Setting the initSelector option.

$( ".selector" ).dialog( "option", 
    "initSelector", "div.custom" );

Getting the initSelector option.

var initSelector = $( ".selector" )
    .dialog( "option", "initSelector" );

CDN Link: First, add jQuery Mobile scripts needed for your project.
