Question

I am developing an app for iOS using Phonegap bundled with jQuery Mobile 1.1.1. I have a div on my page that is listening for both tap and taphold events.

The problem I am facing is that the tap event is fired after the taphold event once I lift my finger. How do I prevent this?
A solution is provided here but is this the only way to do this? Kinda nullifies the whole point of having two different events for tap & taphold if you need to use a boolean flag to differentiate the two.

Following is my code:

$('#pageOne').live('pageshow', function(event) {
    $('#divOne').bind('taphold', function (event) {
       console.log("TAP HOLD!!");    
    });

    $('#divOne').bind('tap', function () {
      console.log("TAPPED!!");
    });
});

Would greatly appreciate the help. Thanks!

I checked jQuery Mobile’s implementation. They are firing the ‘tap’ event after ‘taphold’ every time on ‘vmouseup’.

Workaround would be not to fire the ‘tap’ event if the ‘taphold’ has been fired. Create a custom event or modify the source as per you need as follows:

$.event.special.tap = {
    tapholdThreshold: 750,

    setup: function() {
        var thisObject = this,
            $this = $( thisObject );

        $this.bind( "vmousedown", function( event ) {

            if ( event.which && event.which !== 1 ) {
                return false;
            }

            var origTarget = event.target,
                origEvent = event.originalEvent,
                /****************Modified Here**************************/
                tapfired = false,
                timer;

            function clearTapTimer() {
                clearTimeout( timer );
            }

            function clearTapHandlers() {
                clearTapTimer();

                $this.unbind( "vclick", clickHandler )
                    .unbind( "vmouseup", clearTapTimer );
                $( document ).unbind( "vmousecancel", clearTapHandlers );
            }

            function clickHandler( event ) {
                clearTapHandlers();

                // ONLY trigger a 'tap' event if the start target is
                // the same as the stop target.
                /****************Modified Here**************************/
                //if ( origTarget === event.target) {
                 if ( origTarget === event.target && !tapfired) {
                     triggerCustomEvent( thisObject, "tap", event );
                 }
            }

            $this.bind( "vmouseup", clearTapTimer )
                .bind( "vclick", clickHandler );
            $( document ).bind( "vmousecancel", clearTapHandlers );

            timer = setTimeout( function() {
                tapfired = true;/****************Modified Here**************************/
                triggerCustomEvent( thisObject, "taphold", $.Event( "taphold", { target: origTarget } ) );
            }, $.event.special.tap.tapholdThreshold );
        });
    }
};
