    In this article, you will learn about the javascript ionic events. These events are useful when you want to interact your web application pages with user.
    These are ionic events:

    • on-hold : It is called when user touches screen for more than 500ms.
    • on-tap : It is called when user touches screen for less than 250ms.
    • on-double-tap : It is called when user does double tap on touch screen.
    • on-touch : It is called at the time when user touches the screen.
    • on-release : It is called when touch is released.
    • on-drag : It is called when user touches the screen and move around the screen in any direction without releasing.
    • on-drag-up : It is called when any html element is dragged up.
    • on-drag-right : It is called when any html element is dragged to right.
    • on-drag-left : It is called when any html element is dragged to left.
    • on-drag-down : It is called when any html element is dragged down.
    • on-swipe : It is called when user drags element in high velocity moving in any direction.
    • on-swipe-up : It is called when user drags element in high velocity moving upwards.
    • on-swipe-right : It is called when user drags element in high velocity moving to right direction.
    • on-swipe-left : It is called when user drags element in high velocity moving to left direction.
    • on-swipe-down : It is called when user drags element in high velocity moving downwards.

    Using Events:

    You can use these ionic events by just adding them on element. Here we have created a button and add on-touch event that will call onTouchFunction() that is defined in javascript file.

    <button on-touch = "onTouchFunction()" class="button">click here</button>
    $scope.onTouchFunction = function() {
       // Do something...
    }

    when touch event will be called the function onTouchFunction() executes.
