I know this function:
document.addEventListener('touchstart', function(event) {
alert(event.touches.length);
}, false);
But is it possible to add this to a div? Example:
document.getElementById("div").addEventListener('touchstart', function(event) {
alert(event.touches.length);
}, false);
I haven't tested it yet, maybe some of you know if it works?
Yeah, that's how you do it.
document.getElementById("div").addEventListener("touchstart", touchHandler, false);
document.getElementById("div").addEventListener("touchmove", touchHandler, false);
document.getElementById("div").addEventListener("touchend", touchHandler, false);
function touchHandler(e) {
if (e.type == "touchstart") {
alert("You touched the screen!");
} else if (e.type == "touchmove") {
alert("You moved your finger!");
} else if (e.type == "touchend" || e.type == "touchcancel") {
alert("You removed your finger from the screen!");
}
}
Or with jQuery
$(function(){
$("#div").bind("touchstart", function (event) {
alert(event.touches.length);
});
});
