jQuery UI is a web-based technology and consists of GUI widgets, visual effects, and themes implemented using the jQuery, JavaScript Library. jQuery UI is the best tool for building UI interfaces for the webpages. It can also be used to build highly interactive web applications or can be used to add widgets easily.
In this article, we will learn how to use the jQuery UI Droppable tolerance Option. This option is used to determine which mode to use for testing whether a draggable is hovering over a droppable. The default value of this option is “intersect”.
The following are the possible values:
- “fit”: It specifies the draggable overlaps the droppable entirely.
- “intersect”: It specifies the draggable overlaps the droppable at least 50% in both directions.
- “pointer”: It specifies the mouse pointer overlaps the droppable.
- “touch”: It specifies the draggable overlaps the droppable any amount.
Syntax:
The tolerance option takes an above-defined type value and the syntax is as follows.
$( ".selector" ).draggable({
tolerance: "fit"
});-
Get the tolerance option
var tolerance = $( ".selector" ).droppable( "option", "tolerance" );
-
Set the tolerance option
$( ".selector" ).droppable( "option", "tolerance", "fit" );
CDN Link: The following jQuery Mobile scripts will be needed for your project so we need to add these scripts to your project.
