• CSS3 transition属性


    1. Transition(过渡),设置过渡时间,(transition-duration)
      <head>
          <title>无标题文档</title>
          <style>
              .box{width:100px;height:100px;background:red; transition:500ms;}
              .box:hover{ background:blue;width:200px;height:200px;}
          </style>
      </head>
      <body>
          <div class="box"></div>
      </body>
    2. 只设置某一个样式过渡,即要运动的样式,下面的例子设置了width过渡(all | width | height | ... | none):
      <head>
          <title>无标题文档</title>
          <style>
              .box{width:100px;height:100px;background:red; transition:500ms width;}
              .box:hover{ background:blue;width:200px;height:200px;}
          </style>
      </head>
      <body>
          <div class="box"></div>
      </body>
    3. 设置运动形式:transition-timing-function (ease[默认值,逐渐变慢], linea[匀速], ease-in[加速], ease-out[减速], ease-in-out[先加速后减速], cubic-besizer[贝塞尔曲线](http://matthewlein.com/ceaser/))
      <head>
          <title>无标题文档</title>
          <style>
              .box{width:100px;height:100px;background:red; transition:5s width cubic-bezier(0.145,1.295,0.000,1.610);}
              .box:hover{width:500px;}
          </style>
      </head>
      <body>
          <div class="box"></div>
      </body>
    4. 同时设置多个样式的过渡时间,用逗号分隔开,如下
      <head>
          <title>无标题文档</title>
          <style>
              .box{width:100px;height:100px;background:red; transition:1s width,2s height,3s background;}
              .box:hover{width:500px;height:300px;background:blue;}
          </style>
      </head>
      <body>
          <div class="box"></div>
      </body>
    5. 设置延迟时间,transition-delay,即多长时间后开始某个运动,下面的例子中在1s之后高度开始过渡
       1 <head>
       2     <title>无标题文档</title>
       3     <style>
       4         .box{width:100px;height:100px;background:red; transition:1s width,2s 1s height,3s 3s background;}
       5         .box:hover{width:500px;height:300px;background:blue;}
       6     </style>
       7 </head>
       8 <body>
       9     <div class="box"></div>
      10 </body>
    6. 过渡结束时触发指定的执行函数,在过渡结束时,执行alert(“end”)
      <head>
          <title>无标题文档</title>
          <style>
              .box{width:100px;height:100px;background:red; transition:1s width;}
          </style>
      </head>
      <body>
          <div class="box" id="box"></div>
          <script>
              var oBox=document.getElementById("box");
              oBox.onclick=function()
              {
                this.style.width=this.offsetWidth+100+"px";
              };
              addEnd(oBox,function(){
                alert("end");    
              });
              function addEnd(obj,fn)
              {
                obj.addEventListener('WebkitTransitionEnd',fn,false);
                obj.addEventListener('transitionend',fn,false);
              }
          </script>
      </body>
    7. 过渡完成事件
      • Webkit内核: obj.addEventListener('webkitTransitionEnd', function(){}, false);
      • firefox内核:obj.addEventListener('transitionend', function(){}, false);
