mui轮播图有点击预览功能，但是这个预览放大，只是和原图大小一样，有时候要让图片变的更大就要想其它办法了
第一种

<script type="text/javascript" src="js/mui.js"></script>
<script type="text/javascript" src="js/jquery-2.2.2.min.js"></script>
<script type="text/javascript">
$(function () {
$(".bannerimg").click(function () {
var width = $(this).width();
if(width==203){
$(".bannerimg").animate({width: "80%", height: "200%", margin: "30px 10%"}, 100)
}else {
$(".bannerimg").animate({width: "203px",height:"350px", margin:"0 25%"}, 100)
}
})
})
</script></html>
对应的css
.mui-slider{
position: relative;
z-index: 1;
overflow: hidden;
width: 100%;
}
.mui-slider .mui-slider-group{
font-size: 0;
position: relative;
-webkit-transition: all 0s linear;
transition: all 0s linear;
white-space: nowrap;
}
.mui-slider .mui-slider-group .mui-slider-item{
font-size: 14px;
position: relative;
display: inline-block;
width: 100%;
height: 100%;
vertical-align: top;
white-space: normal;
border: 4px solid red;
}
.mui-slider .mui-slider-group .mui-slider-item img{
width: 50%;
margin: 0 25%;}
这种把mui.zoom.js和mui,previewimg.js去掉，去掉轮播功能，通过jquery实现放大缩小，不足之处就是不支持手势缩放。
第二种,
图片放大还支持手势缩放

最开始想的办法是改Js，改了一会不行，还是另想它法从css入手了
1，先把原生的这行css代码给干掉，因为它是点击前后共有的css样式,而预览图片又是另一个样式
2,这里的代码一定要放在自己的css里
