This time I will bring you the function of clicking on the image to enlarge in vue (with code). What are the precautions for vue to implement the function of clicking on the image to enlarge. The following is a practical case, let's take a look.
1. Create a subcomponent to implement the image method function: BigImg.vue
<template> <!-- 过渡动画 --> <transitionname="fade"> <pclass="img-view"@click="bigImg"> <!-- 遮罩层 --> <pclass="img-layer"></p> <pclass="img"> <img:src="imgSrc"> </p> </p> </transition> </template> <script> export default { props: ['imgSrc'],//接受图片地址 methods: { bigImg() { // 发送事件 this.$emit('clickit') } } } </script> <stylescoped> /*动画*/ .fade-enter-active, .fade-leave-active { transition: all .2s linear; transform: translate3D(0, 0, 0); } .fade-enter, .fade-leave-active { transform: translate3D(100%, 0, 0); } /* bigimg */ .img-view { position: inherit; width: 100%; height: 100%; } /*遮罩层样式*/ .img-view .img-layer { position: fixed; z-index: 999; top: 0; left: 0; background: rgba(0, 0, 0, 0.7); width: 100%; height: 100%; overflow: hidden; } /*不限制图片大小,实现居中*/ .img-view .img img { max-width: 100%; display: block; position: absolute; left: 0; right: 0; margin: auto; z-index: 1000; } </style>
2. Use subcomponents in the parent class:
<templatexmlns:v-on="http://www.w3.org/1999/xhtml"> <pclass="contents"> <pclass="group"> <pclass="special"> <spanv-text="pagedata.subtitle"></span> </p> <spanclass="text-muted"v-text="pagedata.headline"></span> <pclass="group_img"> <!-- 放大图片 --> <big-imgv-if="showImg"@clickit="viewImg":imgSrc="imgSrc"></big-img> <pclass="text"v-text="pagedata.article"></p> <imgid="smallImg":src="pagedata.imgurl"@click="clickImg($event)"> </p> </p> </p> </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>
