vue 点击图片查看大图

1.建立子组件,来实现图片方法功能: BigImg.vue

<template>
    <!-- 过渡动画 -->
    <transition name="fade">
      <div class="img-view" @click="bigImg">
        <!-- 遮罩层 -->
        <div class="img-layer"></div>
        <div class="img">
          <img :src="imgSrc">
        </div>
      </div>
  </transition>
</template>
<script>
  export default {
    props: ['imgSrc'],//接受图片地址
    methods: {
      bigImg() {
      // 发送事件
        this.$emit('clickit')
      }
    }
  }
</script>
<style scoped>
  /*动画*/
  .fade-enter-active,
  .fade-leave-active {
    transition: all .2s linear;
    transform: translate3D(0, 0, 0);
  }
  .fade-enter,
  .fade-leave-active {
    transform: translate3D(100%, 0, 0);
  }
 
  /* bigimg */
  .img-view {
    position: inherit;
    width: 100%;
    height: 100%;
  }
  /*遮罩层样式*/
  .img-view .img-layer {
    position: fixed;
    z-index: 999;
    top: 0;
    left: 0;
    background: rgba(0, 0, 0, 0.7);
    width: 100%;
    height: 100%;
    overflow: hidden;
  }
  /*不限制图片大小,实现居中*/
  .img-view .img img {
    max-width: 100%;
    display: block;
    position: absolute;
    left: 0;
    right: 0;
    margin: auto;
    z-index: 1000;
  }
</style>

 

2.在父类中使用子组件:

<template xmlns:v-on="http://www.w3.org/1999/xhtml">
  <div class="contents">
    <div class="group">
      <div class="special">
        <span v-text="pagedata.subtitle"></span>
      </div>       <span class="text-muted" v-text="pagedata.headline"></span>       <div class="group_img">         <!-- 放大图片 -->         <big-img v-if="showImg" @clickit="viewImg" :imgSrc="imgSrc"></big-img>            <div class="text" v-text="pagedata.article"></div>         <img :src="pagedata.imgurl" @click="clickImg($event)">       </div>     </div>   </div> </template> <script> import BigImg from '../../index/moduleStyles/BigImg.vue'; export default {   data () {     return {       showImg:false,       imgSrc: ''     }   },   props: ['pagedata'],   computed: {},   components: { 'big-img':BigImg},   methods: {     clickImg(e) {       this.showImg = true;       // 获取当前图片地址       this.imgSrc = e.currentTarget.src;     },     viewImg(){       this.showImg = false;     },   },   watch: {}, } </script> <style> </style>
