How to stop event propagation with inline onclick attribute?

Question

Consider the following:

<div onclick="alert('you clicked the header')" class="header">
  <span onclick="alert('you clicked inside the header');">something inside the header</span>
</div>

How can I make it so that when the user clicks the span, it does not fire the div's click event?

Answer 1

Use event.stopPropagation().

<span onclick="event.stopPropagation(); alert('you clicked inside the header');">something inside the header</span>

For IE: window.event.cancelBubble = true

<span onclick="window.event.cancelBubble = true; alert('you clicked inside the header');">something inside the header</span>
