Is there a way to make to work the mootools class "Drag" on Safari mobile? Please don't link me to other frameworks.
Here was my solution to making Mootools Drag support touch events. This method didn't require me to edit the mootools more file since i used Class.refactor (This is only tested with Mootools v.1.3.1) -- it also does not break the usual click events
Class.refactor(Drag,
{
attach: function(){
this.handles.addEvent('touchstart', this.bound.start);
return this.previous.apply(this, arguments);
},
detach: function(){
this.handles.removeEvent('touchstart', this.bound.start);
return this.previous.apply(this, arguments);
},
start: function(event){
document.body.addEvents({
touchmove: this.bound.check,
touchend: this.bound.cancel
});
this.previous.apply(this, arguments);
},
check: function(event){
if (this.options.preventDefault) event.preventDefault();
var distance = Math.round(Math.sqrt(Math.pow(event.page.x - this.mouse.start.x, 2) + Math.pow(event.page.y - this.mouse.start.y, 2)));
if (distance > this.options.snap){
this.cancel();
this.document.addEvents({
mousemove: this.bound.drag,
mouseup: this.bound.stop
});
document.body.addEvents({
touchmove: this.bound.drag,
touchend: this.bound.stop
});
this.fireEvent('start', [this.element, event]).fireEvent('snap', this.element);
}
},
cancel: function(event){
document.body.removeEvents({
touchmove: this.bound.check,
touchend: this.bound.cancel
});
return this.previous.apply(this, arguments);
},
stop: function(event){
document.body.removeEvents({
touchmove: this.bound.drag,
touchend: this.bound.stop
});
return this.previous.apply(this, arguments);
}
});
