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>
