vue 使用 better-scroll 上拉反弹，

Question

<div class="pull-info-info">

 <div v-html="detaisContent"></div>          

</div>
detaisContent =》里面包含图片

better() { //BScroll

this.$nextTick(() => {
    if(!this.scroll){
        this.scroll = new BScroll(this.$refs.questionsWrapper, {
            click:true
        })
    }else {
        this.scroll.refresh()
    }
})

},

mounted(){

this.better()  //BScroll

},

//我使用下面这种方法也是不行
watch:{

GoodsDetaiInfo(newValue){
    this.$nextTick(() => {
         this.scroll.refresh()
    })
}

}
