解决Vue使用swiper动态加载数据,动态轮播数据显示白屏的问题

<div class="swiper-container"> <div class="swiper-wrapper"> <div class="swiper-slide tpOne" v-if="topInfo">  <-- 此处为绑定数据的轮播元素 -->  <div class="bannerBox1">  <div class="l_label" >{{topInfo.label}}</div>  <div class="l_title" >{{topInfo.title}}</div>  <div class="l_tips" >{{topInfo.tips}}</div>  <div class="l_bottom"><span><img src="..." alt=""></span>{{topInfo.bottom}}</div>  </div> </div> <div class="swiper-slide"><img src="" alt="" /></div> <div class="swiper-slide"><img src="" alt="" /></div> <div class="swiper-slide"><img src="" alt="" /></div> </div> <div class="swiper-pagination"></div></div>

//mounted 或者topInfo的值获取到时再调用初始化方法swiperInit() { var mySwiper = new Swiper('.swiper-container', {  pagination : '.swiper-pagination',  paginationType : 'bullets',  autoplay : 2000,  // loop : true, })},

getInfo:function(){ var _this=this; XXX.ajax({  url: '...',  success: (r)=> {  if(!!r.ret){   _this.topInfo=r.ret;   //此时获取到数据再显示Swiper   _this.getFlag=1;  }  } }) },

<div class="swBox" v-if="sw_flag&&!!banners.length"> <div class="swiper-container"> <div class="swiper-wrapper">  <div class="swiper-slide" v-for="(banner,index) in banners" :key="index" @click="toNextUrl(banner,index)">  <img :src="banner.image" alt="" />  </div> </div> <div class="swiper-pagination"></div> </div></div>

swiperInit() { var mySwiper = new Swiper('.swiper-container', {  pagination : '.swiper-pagination',  paginationType : 'bullets',  autoplay : 2000,  observer:true,  observeParents:false }) },

getData:function(){ var _this=this; //此处设置sw_flag变量的目的在于控制swiper显示关闭开关，当数据重新请求时，先关闭swiper，请求完毕数据再重新渲染页面； _this.sw_flag=0; XXX.ajax({ url: '...', success: (r)=> {  if(!!r.ret){  _this.banners=r.ret.banners||"";  _this.sw_flag=1;  //此时获取到数据再初始化swiper  _this.$nextTick(function(){   if(!!_this.banners.length){   _this.swiperInit();   }  });  } } })},
