vant 使用 ImagePreview 预览图片

场景1

编列数组生成图片，点击预览图片

    <div class="zoom"
         v-for="(item, index) in listData"
         v-show="item"
         :key="index"
         >
              <img
                v-if="item"
                class="img"
                :src="item"
                alt="预览图片"
                @click="getImg(listData, index)"
              />
            </div>
<script>
import { ImagePreview } from "vant";
export default {
  name: "ImagePreview ",
  data() {
    return {
      listData: ["1.jpg","2.jpg"],//图片数组
    };
  },
  methods: {
    getImg(images, index) {
      ImagePreview({
        images: this.listData,
        showIndex: true,
        loop: false,
        startPosition: index
      });
    }
  },
  computed: { },
  created() {}
};
</script>

场景2

一个用字符串，用，分割为数组，编列数组生成图片，点击预览图片

   <div class="zoom"
         v-for="(item, index) in imgstr && imgstr.split(',')"
         v-show="item"
         :key="index"
         >
              <img
                v-if="item"
                class="img"
                :src="item"
                alt="预览图片"
                @click="getImg(imgstr , index)"
              />
            </div>
<script>
import { ImagePreview } from "vant";
export default {
  name: "ImagePreview ",
  data() {
    return {
    imgstr :"1.jpg,2.jpg"
    imglist: []
    };
  },
  methods: {
   this.imglist = [];
      const imgurls = imgstr.split(",");
      for (let index = 0; index < imgurls.length; index++) {
        this.imglist.push(this.viewImgs(imgurls[index]));
      }
      ImagePreview({
        images: this.imglist,
        showIndex: true,
        loop: false,
        startPosition: index
      });
  },
  computed: { },
  created() {}
};
</script>
