APICloud 实现 使用openFrameGroup引入页面后禁止上下滑动

function funIniGroup(){
        var eHeaderLis = $api.domAll('header li'),
            frames = [];
        for (var i = 0,len = eHeaderLis.length; i < len; i++) {
                frames.push( {
                    name: 'frame'+i,
                    url: './html/frame'+i+'.html',
                    bgColor : 'rgba(0,0,0,.2)',
                    bounces:false    //  这里修改为  false  即可
                } )
        }
        api.openFrameGroup({
            name: 'group',
            scrollEnabled: true,
            rect: {
                x: 0,
                y: $api.dom('header').offsetHeight,
                w: api.winWidth,
                h: $api.dom('#main').offsetHeight
            },
            index: 0,
            frames: frames
        }, function (ret, err) {

        });
    }
