transform应用详解

关于css3的transform，做了一个demo，上代码

html：

 <!DOCTYPE html>

 <html>

 <head lang="en">

 <link rel="stylesheet" href="practice.css" type="text/css" >

 <script src="../js/jquery-2.1.1.min.js" type="text/javascript" ></script>

 <meta charset="UTF-8">

 <title>transform</title>

 </head>

 <body>

 <div class="container">

   <div class="out">

       <ul>

          <li class="in"><img src='1.jpg' /></li>

          <li class="in"><img src='2.jpg' /></li>

          <li class="in"><img src='3.jpg' /></li>

          <li class="in"><img src='4.jpg' /></li>

          <li class="in"><img src='5.jpg' /></li>

       </ul>

   </div>

   <div class="control">

      <div class='detail'>

         <span>transform-style:&nbsp;&nbsp;&nbsp;flat:<input type="radio" name='style' value='flat'/>&nbsp;&nbsp;&nbsp;preserve-3d:<input type="radio" name='style' value='preserve-3d' /></span>

         <p>你选择transform_style为<span></span></p>

      </div>

      <div class='detail'>

         <span>perspective:</span><input name='perspective' type="range" min='0' max='800' value='0' step='1'/>

         <p>你选择的perspective值为<span></span></p>

      </div>

      <div class='detail'>

         <span>translateX:</span><input name='translateX'  type="range" min='0' max='50' value='0' step='1'/>

         <p>你选择的translateX值为<span></span></p>

      </div>

      <div class='detail'>

         <span>translateY：</span><input name='translateY' type="range" min='0' max='50' value='0' step='1'/>

         <p>你选择的translateY值为<span></span></p>

      </div>

      <div class='detail'>

         <span>translateZ：</span><input name='translateZ' type="range" min='0' max='50' value='0' step='1'/>

         <p>你选择的translateZ值为<span></span></p>

      </div>

      <div class='detail'>

         <span>rotateX：</span><input name='rotateX' type="range" min='0' max='180' value='0' step='1'/>

         <p>你选择的rotateX值为<span></span></p>

      </div>

      <div class='detail'>

         <span>rotateY：</span><input name='rotateY' type="range" min='0' max='180' value='0' step='1'/>

         <p>你选择的rotateY值为<span></span></p>

      </div>

      <div class='detail'>

         <span>rotateZ：</span><input name='rotateZ' type="range" min='0' max='180' value='0' step='1'/>

         <p>你选择的rotateZ值为<span></span></p>

      </div>

   </div>

 </div>

css比较简单，就不上了

js:

<script>

$(function(){

    var transform_style='flat',translateX='0px',translateY='0px',translateZ='0px',perspective='0px',rotateX=0,rotateY=0,rotateZ=0;

    $("input").on('change',function(){

        if($(this).attr('name')==='style'){

            if($(this).is(":checked")){

                transform_style=$(this).val();

                $("ul").css({"transform-style":transform_style});

                $(this).parent().siblings('p').find('span').text(transform_style)    ;

            }

        }else{

            var change=$(this).attr('name');

            var val=$(this).val();

            switch(change){

                case 'perspective':

                    perspective=val+'px';

                    break;

                case 'translateX':

                    translateX=val+'px';

                    break;

                case 'translateY':

                   translateY=val+'px';

                   break;

                case 'translateZ':

                   translateZ=val+'px';

                   break;

                case 'rotateX':

                    rotateX=val;

                    break;

                case 'rotateY':

                   rotateY=val;

                   break;

                case 'rotateZ':

                   rotateZ=val;

                   break;

            }

            $(this).siblings('p').find('span').text(val);

            $('.in').css({'-webkit-transform':'perspective('+perspective+') translate3d('+translateX+','+translateY+','+translateZ+') rotateX('+rotateX+'deg) rotateY('+rotateY+'deg) rotateZ('+rotateZ+'deg)'})

        }

    })

})

</script>
