解决方法
我建议添加一个隐藏的div：
<div id="message"> This is a message </div>
用CSS：
#message { position: absolute; display: none; }
然后显示出来：
$("#equipment").click(function(evt) {
$("#message").css({
top: evt.pageY,left: evt.pageX
}).toggle();
});
这是一个完整的例子：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$("#equipment").click(function(evt) {
$("#message").css({
top: evt.pageY + 5,left: evt.pageX + 5
}).show();
});
});
</script>
<style type="text/css">
html,body,div { margin: 0; padding: 0; border: 0 none; }
#wrapper { margin: 0 auto; width: 600px; }
#equipment { color: green; }
#message { display: none; position: absolute; text-align: center; padding: 10px; width: 120px; background: red; color: white; font-weight: bold; }
</style>
</head>
<body>
<div id="wrapper">
