需要进行图片缩放,代码如下

复制代码
 1 <html>
 2 <head>
 3     <meta http-equiv="Content-Type" content="text/html;charset=gb2312" />
 4     <title> 图片放大缩小</title>
 5     <script type="text/javascript">
 6         var scrollFunc = function (e) {
 7             var direct = 0;
 8             e = e || window.event;
 9             var img = document.getElementById("zoom");
10             var zoom = parseInt(img.style.zoom, 10);
11             if (isNaN(zoom)) {
12                 zoom = 100;
13             }
14             if (e.wheelDelta) {
15                 zoom += e.wheelDelta / 120;
16                 if (zoom > 10) img.style.zoom = zoom + "%";
17             }
18             else
19                 if (e.detail) {
20                     zoom += -e.detail / 3;
21                     if (zoom > 10)
22                         img.style.MozTransform = scale(zoom + "%").style.MozTransformOrigin = TopLeft;
23                 }
24             ScrollText(direct);
25         }
26         if (document.addEventListener) {
27             document.addEventListener('DOMMouseScroll', scrollFunc, false);
28         }
29         window.onmousewheel = document.onmousewheel = scrollFunc;
30     </script>
31 </head>
32 <body>
33     <div id="zoom" style="position:relative;width:auto; display:inline-block !important; display:inline; border:1px solid #F00;">
34         <img src="1.jpg" class="one" />
35         <div style="position:absolute;width:70px;left:50%;top:50%; border:1px solid #F00;">
36             <img src="2.jpg">
37         </div>
38     </div>
39 </body>
40 </html>
复制代码

22行这点不知道该怎么写了,

 img.style.MozTransform = scale(zoom + "%").style.MozTransformOrigin = TopLeft;这个火狐还是不兼容

                        img.style.zoom = zoom + "%"
                        img.style.transform = "scale("+zoom/100+")";

transform 赋值应为字符串,还有img.style.zoom虽然不支持,但是要用来记录缩放的值
