UIScrollPicture 是一个图片轮播模块，只需传入一组图片地址，即可实现图片轮播效果。

function Scroll(){
      banner = $api.byId('banner')
       ,bannerH = $api.offset(banner).h;

    var UIScrollPicture = api.require('UIScrollPicture');
    UIScrollPicture.open({
        rect: {
            x: 0,
            y: 0,
            w: api.winWidth,
            h: bannerH
        },
        data: {
            paths: [
                'http://dyh.chinadatatrading.com/static/img/b1.jpg',
                'http://dyh.chinadatatrading.com/static/img/b2.jpg'
            ],
            captions: []
        },
        styles: {
            caption: {},
            indicator: {
                align: 'center',
                color: '#fff',
                activeColor: '#d0cdd1'
            }
        },
        placeholderImg: 'http://img.lanrentuku.com/img/allimg/1212/5-121204193935-51.gif',
        contentMode: 'scaleToFill',
        interval: 3,
        fixedOn: api.frameName,
        loop: true,
        fixed: false
    }, function(ret, err) {
        if (ret) {
            // alert(JSON.stringify(ret));
        } else {
            // alert(JSON.stringify(err));
        }
    });
