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 * 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>
