jQuery自定义Web页面鼠标右键菜单
右键菜单是固定的,很多时候,我们需要自定义web页面自定义菜单,指定相应的功能。
自定义的原理是:jQuery封装了鼠标右键的点击事件(“contextmenu”),首先屏蔽浏览器原始的点击事件,接着,写自己的需要的显示的右键菜单最后,就是什么时候隐藏显示出的右键菜单了。
代码如下:

<script type="text/javascript" src="js/jquery-1.8.2.min.js"></script>

body{ position:relative;}
ul,li{ margin:0; padding:0; list-style:none; font-size:12px;}
.split{border-bottom: 1px solid gray;}
.popup_menu{position:absolute; z-index:90; border:1px solid #AEAEAE; padding:2px; width:120px;border-radius: 2px;}
.popup_menu a{ display:block; color:#325B8E; text-indent:12px; text-decoration:none; height:26px; line-height:25px; padding-right:5px;}
.popup_menu a:hover{ background:#57B4E4; color:#fff; border-radius: 2px;}
</style>
</head>
<body>
<script type="text/javascript">
var kyPopupMenu={};
kyPopupMenu = (function(){
return {
right: function (obj) {
$('.popup_menu').remove();
var menu = '<div class="popup_menu app-menu"><ul><li><a url="http://www.cnblogs.com/mini-firework/">firework</a></li><li class="split"></li><li><a url="http://blog.csdn.net/e_real">疯狂的土豆专栏</a></li><li><a url="http://blog.163.com/qiuyg_yc_it/">网易博客</a></li></ul></div>';
popupMenuApp = $(menu)
.find('a').attr('href','javascript:;')
.end().appendTo('body');
//绑定事件
$('.app-menu a').on('click', function (){
window.location.href=$(this).attr("url");
});
return popupMenuApp;
}
};
})();
//取消右键
$('html').on('contextmenu', function (){return false;}).click(function(){
$('.popup_menu').hide();
});
//桌面点击右击
$('html').on('contextmenu',function (e){
var popupmenu = kyPopupMenu.right();
l = ($(document).width() - e.clientX) < popupmenu.width() ? (e.clientX - popupmenu.width()) : e.clientX;
t = ($(document).height() - e.clientY) < popupmenu.height() ? (e.clientY - popupmenu.height()) : e.clientY;
popupmenu.css({left: l,top: t}).show();
return false;
});
</script> </body>
</html>
