On () method

The on () method adds one or more event handlers to the selected element and its children.

Since jQuery version 1.7, the on () method is a new alternative to the bind (), live (), and delegate () methods. This method brings a lot of convenience to API. It is recommended to use this method, which simplifies the jQuery code base.

Note: event handlers added using the on () method apply to current and future elements (such as new elements created by scripts).

Tip: to remove the event handler, use the off () method.

Tip: to add an event that runs only once and remove it, use the one method.

$(selector) .on (event,childSelector,data,function,map)
