检测Div Box中的触摸？ 使用Javascript

Question

Say I have setup a basic div like this :

<div id='signatureBox'></div>

I then want to register whenever the box is clicked on / touched in any area. I am trying without success :

//Register signature callback
var signature = document.getElementById("signatureBox");
signature.onclick() = function () {
alert('signature JavaScript triggered');
        }

Can anyone help ?

Thanks !

Answer 1

You've put in the parentheses which are unneeded for the onclick in javascript. Correct working code is here

var signature = document.getElementById("signatureBox");
signature.onclick = function () {
    alert('signature JavaScript triggered');
}
