When tracking which elements were clicked e.target.id is sometimes empty [migrated]
- by Ivan
I am trying to test the following JavaScript code, which is meant to keep track of the timing of user responses on a multiple choice survey:
document.onclick = function(e) {
var event = e || window.event;
var target = e.target || e.srcElement;
//time tracking
var ClickTrackDate = new Date;
var ClickData = "";
ClickData = target.id + "=" + ClickTrackDate.getUTCHours() + ":" + ClickTrackDate.getUTCMinutes() + ":" + ClickTrackDate.getUTCSeconds() +";";
document.getElementById("txtTest").value += ClickData;
alert(target.id); // for testing
}
Usually target.id equals to the the id of the clicked element, as you would expect, but sometimes target.id is empty, seemingly at random, any ideas?
