Style attributes which are defined in a <style> section or in an external
<link>ed file are not accessible from JavaScript. Only inline defined style
attributes can be accessed.
Reproducible: Always
Steps to Reproduce:
<html>
<head>
<style type="text/css">
div {
background-color: #ddd;
}
</style>
</head>
<body>
<div onclick="alert(this.style.backgroundColor);">muh</div>
</body>
</html>
Actual Results:
The popup window is empty.
Expected Results:
The string "#ddd" or an equivalent to be displayed in the popup window.
Changing the line
<div onclick="alert(this.style.backgroundColor);">muh</div>
to
<div style="background-color: #ddd;"
onclick="alert(this.style.backgroundColor);">muh</div>
fixes the behaviour.
Anyway, I still consider this a bug. IE shows the same beaviour so I really hope
it is in fact a bug and not a feature. :P
I can test this under Linux later, but I don't expect to see it work there.
Same effect for Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041001 Firefox/0.10.1
