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 Popup widget 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 Popup widgets on every element of the following list.

Syntax:

Initializing the Popup with the specified initSelector option.

$( "Selector" ).popup({
     initSelector: "div.custom"
});

Setting the initSelector option.

$( "Selector" ).popup( "option", "initSelector", "div.custom" );

Getting the initSelector option.

var a = $( "Selector" ).popup( "option", "initSelector" );
