<h1>The cancelBubble Property</h1>
<p>Click DIV 1:</p>
<div onclick="func2()">DIV 2
<div onclick="func1(event)">DIV 1</div>
</div>
Cancel bubble:
<input type="checkbox" id="check">
<p></p>
<p>Because DIV 1 is inside Div 2, both DIVs get clicked when you click on DIV 1.</p>
<p>Check the cancel bubble checkbox, and try again.</p>
<p>The cancelBubble = true prevents the event flow from bubbling up to parent elements.</p>

alert("DIV 1");
if (document.getElementById("check").checked) {
event.cancelBubble = true;
}
