js 代码

"text/javascript">
$(document).ready(function(){
$(".stripeMe tr").mouseover(function() {$(this).addClass("over");}).mouseout(function() {$(this).removeClass("over");});
$(".stripeMe tr:even").addClass("alt");
});

 

$('p') = find all paragraphs

$('.whatever') = find everything with class="whatever"

$('.stripeMe tr') = find all tr (table rows) inside an element with the "stripeMe" class

In the code:$(".stripeMe tr").... find all rows of a table with class="stripeMe"

the code:$(".stripeMe tr:even")......any table with class name "stripeMe" will be striped

$('.whatever').mouseover() tells jQuery "Everything with class name 'whatever' will have a new onMouseover event
