基于jQuery实现鼠标点击导航菜单水波动画效果

基于jQuery鼠标点击水波动画竖直导航代码。这是一款基于jQuery+CSS3实现的带动画效果的竖直导航栏特效。效果图如下：

html代码：

<div class="nav">

<ul>

<li><a>网站首页</a></li>

<li><a>关于我们</a></li>

<li><a>产品中心</a></li>

<li><a>成功案例</a></li>

<li><a>联系我们</a></li>

<li><a>在线留言</a></li>

</ul>

</div>

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

<script type="text/javascript">

//jQuery time

var parent, ink, d, x, y;

$(".nav ul li a").click(function (e) {

parent = $(this).parent();

//create .ink element if it doesn't exist

if (parent.find(".ink").length == 0)

parent.prepend("<span class='ink'></span>");

ink = parent.find(".ink");

//incase of quick double clicks stop the previous animation

ink.removeClass("animate");

//set size of .ink

if (!ink.height() && !ink.width()) {

//use parent's width or height whichever is larger for the diameter to make a circle which can cover the entire element.

d = Math.max(parent.outerWidth(), parent.outerHeight());

ink.css({ height: d, width: d });

}

//get click coordinates

//logic = click coordinates relative to page - parent's position relative to page - half of self height/width to make it controllable from the center;

x = e.pageX - parent.offset().left - ink.width() / 2;

y = e.pageY - parent.offset().top - ink.height() / 2;

//set the position and add class .animate

ink.css({ top: y + 'px', left: x + 'px' }).addClass("animate");

})

</script>
