mui动态添加轮播图片，我用mui.ajax获取后台数据，但是js效果没有了，有什么解决办法没有

success:function(data){  
    console.log(JSON.stringify(data));  
    var good_name = document.getElementById("goods_name");  
    var good_price = document.getElementById("goods_price");  
    var goods_market_price = document.getElementById("goods_market_price");  
    var goods_image = document.getElementById("goods_image");  
    good_name.innerHTML = data.data.name;  
    good_price.innerHTML = data.data.price;  
    goods_market_price.innerHTML = data.data.market_price;  
    console.log(getJsonObjLength(data.data.imagePath));  
    console.log(data.data.imagePath[0]);  
    var imgPT = getJsonObjLength(data.data.imagePath);//获取图片个数  
    for (var i = 0; i<(imgPT+2);i++) {  
        var imgs = document.createElement('div');  
        if(i == 0){  
            imgs.className = 'mui-slider-item mui-slider-item-duplicate';  
            imgs.innerHTML = '<a href="#"><img src="'+data.data.imagePath[(imgPT-1)]+'"></a>';  
        }else if(i == (imgPT+1)){  
            imgs.className = 'mui-slider-item mui-slider-item-duplicate';  
            imgs.innerHTML = '<a href="#"><img src="'+data.data.imagePath[0]+'"></a>';  
        }else{  
            imgs.className = 'mui-slider-item';  
            imgs.innerHTML = '<a href="#"><img src="'+data.data.imagePath[i-1]+'"></a>';  
        }  
        goods_image.appendChild(imgs);  
    }  
}

这是返回代码我操作html的，还没完成，。。。新手求指导
