I would like to add some multitouch features to my javascript application when it is accessed from an ios device (and maybe android later).
I want to provide a shift
Ok, I have implemented this solution and it seems to work.
//Initialize the tap touch
function ManageTapTouch() {
this.__enabled__ = false;
}
ManageTapTouch.prototype.init = function(){
$("#hold").bind('touchstart', $.proxy(this.__enable__, this));
$('#hold').bind('touchend', $.proxy(this.__disable__, this));
$('#tap').bind('touchstart', $.proxy(this.__changeColorOnHold__, this));
$('#tap').bind('touchend', $.proxy(this.__changeColorOnOut__, this));
};
ManageTapTouch.prototype.__enable__ = function(event) {
this.__enabled__ = true;
};
ManageTapTouch.prototype.__disable__ = function(event) {
this.__enabled__ = false;
$('body').css('background-color', 'blue');
};
ManageTapTouch.prototype.__changeColorOnHold__ = function(event) {
if (this.__enabled__){
$('body').css('background-color', 'black');
}
};
ManageTapTouch.prototype.__changeColorOnOut__ = function(event) {
$('body').css('background-color', 'blue');
};
new ManageTapTouch().init();
You can see it running here: http://jsfiddle.net/Tb6t6/15/
Also you can try another way on the iPhone using multitouch with: event.originalEvent.touches[0].pageX
and event.originalEvent.touches[0].pageY
where the index is the finger on the screen and event is the event fired on TouchStart
. With this topics you can implement your own version of this action or use the one I propose here.
