vue实现点击图片放大效果

本文实例为大家分享了vue点击图片放大展示的具体代码,供大家参考,具体内容如下

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 id="smallImg" :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>
