平滑的动画菜单

简介 – 说明如何动的

菜单中有这样一个平滑的动画,因为调用的“宽松”的一件事。 Adobe的Flash开发中心的定义会较小与完整。
感谢神奇的jQuery的缓动插件,我们现在可以在Flash的ActionScript环境以外做平滑的动画。
第一步
然后在此菜单结构复制进入网页的主体:
  1. <ul>
  2.         <li class=”green”>
  3.             <p><a href=”#”>Home</a></p>
  4.             <p class=”subtext”>The front page</p>
  5.         </li>
  6.         <li class=”yellow”>
  7.             <p><a href=”#”>About</a></p>
  8.             <p class=”subtext”>More info</p>
  9.         </li>
  10.         <li class=”red”>
  11.             <p><a href=”#”>Contact</a></p>
  12.             <p class=”subtext”>Get in touch</p>
  13.         </li>
  14.         <li class=”blue”>
  15.             <p><a href=”#”>Submit</a></p>
  16.             <p class=”subtext”>Send us your stuff!</p>
  17.         </li>
  18.         <li class=”purple”>
  19.             <p><a href=”#”>Terms</a></p>
  20.             <p class=”subtext”>Legal things</p>
  21.         </li>
  22.     </ul>
    菜单项分配给它的一css的class类,将指定单个菜单的颜色。在每个菜单块是默认情况下,将隐藏副标题。

    第二步 – CSS样式

     

body{
font-family:”Lucida Grande”, arial, sans-serif;
background:#F3F3F3;
}

ul{
margin:0;
padding:0;
}

li{
width:100px;
height:50px;
float:left;
color:#191919;
text-align:center;
overflow:hidden;
}

a{
color:#FFF;
text-decoration:none;
}

p{
padding:0px 5px;
}

.subtext{
padding-top:15px;
}

/*Menu Color Classes*/
.green{background:#6AA63B;}
.yellow{background:#FBC700;}
.red{background:#D52100;}
.purple{background:#5122B4;}
.blue{background:#0292C0;}

第3步 – jQuery动画

我们的jQuery代码都将在创建的JavaScript文件之前调入。
第4步 -添加鼠标动作
  1. $(document).ready(function(){
  2.     //When mouse rolls over
  3.     $(“li”).mouseover(function(){
  4.         $(this).stop().animate({height:’150px’},{queue:false, duration:600, easing: ‘easeOutBounce’})
  5.     });
  6.     //When mouse is removed
  7.     $(“li”).mouseout(function(){
  8.         $(this).stop().animate({height:’50px’},{queue:false, duration:600, easing: ‘easeOutBounce’})
  9.     });
  10. });

在上面的代码中有两个动作。当鼠标移动菜单项,该项目的启动动画,它扩大到150px的身高超过0.6秒。通过插件应用的宽松是的“easeOutBounce导致框”反弹“一点点,因为它达到了动画结束(”走出去“)。当鼠标移出动画的起始大小被触发。

如果您使用的是在一个较大的站点中,简单的替代选择鼠标事件的必要选择(当时“Li”)的元素。

第5步 – 添加一些花式
我们可以添加了背景图片,每个在现场版本和源文件的菜单项来说明一些设计的可能性。有很多其他创造性的方式来添加一些个性菜单。去和实验。如果你来有什么批量的效果,是一定要与我们分享意见。
第6步 -最后给出js代码
