我有一个鼠标悬停函数,应该向我的视口元素添加一个类,但是当我将鼠标悬停在萤火虫中时出现错误:TypeError: jQuery(...).addclass is not a function。
HTML是:
<!DOCTYPE html>
<html>
<head>
<meta charset="<?php bloginfo( 'charset' ); ?>" />
<title><?php wp_title('|','true','right'); ?><?php bloginfo('name'); ?></title>
<meta name="viewport" content="width=device-width" />
<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" />
<?php wp_head(); ?>
</head>
<body <?php body_class($class); ?>>
<header>
<div class="main-logo">
<div id="site-title">
</div><!--.site-title-->
</div><!--main-logo-->
<div class="header-right">
</div><!--header-right-->
</header>
<nav class="main">
<?php wp_nav_menu( array( 'theme_location' => 'main-menu' ) ); ?>
</nav>
<div class="viewport">
<script type="text/javascript"><!--//--><![CDATA[//><!--
jQuery(document).ready(function(jQuery){
jQuery('nav .home a').mouseover(function()
{
jQuery('.viewport').addclass('.viewporthome');
});
});
//--><!]]></script>
</div>
</div>
相关样式有:
.viewport
{
height: 400px;
width: 400px;
position: relative;
top: -90px;
margin: 0 auto;
}
.viewporthome
{
background-image: url('images/Screen2.png');
background-repeat: no-repeat;
background-position: center;
background-attachment: relative;
}
JS文件是:
var hoverhome = 'url("images/Screen2.png")';
var empty = '';
var success = 'SUCCESS!';
//home
jQuery('nav .home a').hover(function()
{
jQuery('.viewport').css('background-image', hoverhome);
});
jQuery('nav .home a').mouseout(function()
{
jQuery('.viewport').css('background-image', empty);
});
