I'm studying jQuery with this tutorial, but one of examples doesn't work.
<html>
<head>
<style type="text/css">
a.test { font-weight: bold; background: #fc0 }
</style>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(doc开发者_开发百科ument).ready(function(){
$("#ol > li").addClass("test");
$("#some").addClass("test");
});
</script>
</head>
<body>
<a href="http://jquery.com/" id="some">Some</a>
<ul id="ol">
<li>one</li>
<li>two</li>
<li>three</li>
</ul>
</body>
</html>
This example apply the "test" style to hyperlink (#some), but doesn't apply this style to the ordered list (#ol). Why?
remove the a from
a.test { font-weight: bold; background: #fc0 }
The a limits it to links (anchor tags).
The JavaScript is OK, the CSS isn't. The CSS rule only applies to links.
To see the effect, change the CSS to:
.test { font-weight: bold; background: #fc0 }
