问题：Mui调用摄像头时，扫描区域错位
document.getElementById("scanSearch").addEventListener('tap', function() {
mui.openWindow({
url: 'scanSearch.html',
id:'scanSearch',
show: {
aniShow: 'pop-in'
}
});
});
解决办法：将动画方式改为fade-in
document.getElementById("scanSearch").addEventListener('tap', function() {
mui.openWindow({
url: 'scanSearch.html',
id:'scanSearch',
show: {
aniShow: 'fade-in'
}
});
});
