Czy można dodać eventlistener do DIV?
Znam tę funkcję:
document.addEventListener('touchstart', function(event) {
alert(event.touches.length);
}, false);
Ale czy można to dodać do div? Przykład:
document.getElementById("div").addEventListener('touchstart', function(event) {
alert(event.touches.length);
}, false);
Nie testowałem jeszcze, może ktoś z was wie? 25

Tak to się robi.
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!");
}
}
Lub z jQuery
$(function(){
$("#div").bind("touchstart", function (event) {
alert(event.touches.length);
});
});

Odwrotnie, jeśli nie używasz addEventListener, prawdopodobnie alternatywą dla uzyskania kontroli nad ID.
$(document).ready(function () {
$('#container1').on("contextmenu", function (e) {
e.preventDefault();
});
});
