wordpress自定义右键菜单功能

A+

摘要

自定义wordpress右键菜单可以进一步扩展博客功能，丰富博客样式，提升用户体验。同时，在一定程度上也可以防止博客被扒。

一、效果预览

二、使用前提

使用该功能，需要确保你的主题已经存在/引入jQuery文件。若主题没有该文件，请将代码

<script type="text/javascript" src="//apps.bdimg.com/libs/jquery/1.9.1/jquery.min.js"></script>

添加至主题根目录下【header.php】文件的<head></head>标签内。

三、操作步骤

直接复制下面的代码到主题根目录下【footer.php】文件的</body>标签前即可。

<style type="text/css">
	a {text-decoration: none;}
	div.usercm{background-repeat:no-repeat;background-position:center center;background-size:cover;background-color:#fff;font-size:13px!important;width:130px;-moz-box-shadow:1px 1px 3px rgba(0,0,0,.3);box-shadow:1px 1px 3px rgba(0,0,0,.3);position:absolute;display:none;z-index:10000;opacity:0.9;}
	div.usercm ul{list-style-type:none;list-style-position:outside;margin:0px;padding:0px;display:block;}
	div.usercm ul li{margin:0px;padding:0px;line-height:35px;border-bottom:1px solid #ccc;}
	div.usercm ul li a{color:#666;padding:0 15px;display:block;}
	div.usercm ul li a:hover{color:#fff;background:rgba(170,222,18,0.88);}
	div.usercm ul li a i{margin-right:10px;}
	a.disabled{color:#c8c8c8!important;cursor:not-allowed;}
	a.disabled:hover{background-color:rgba(255,11,11,0)!important;}
	div.usercm{background:#fff !important;}
</style>

<div class="usercm">
	<ul>

四、代码解释

上面的代码主要分为三大部分，分别是：CSS样式、HTML代码和JS代码。这里，我是为了方便文章编辑，将这三个部分放在一起，童鞋们也可以将CSS样式和JS代码分别放至主题对应的CSS和JS文件中。
代码中，至少需要修改的是JS代码部分的百度熊掌号ID号，其余部分可不做调整。当然，如果你想定制自己的右键菜单，也可以根据上面的结构做出相应的修改。
