Vue 实现图片弹窗展示
使用模态框组件
Vue 中可以通过封装模态框组件实现图片弹窗展示。创建一个可复用的 ImageModal 组件,包含图片展示区域和关闭按钮。
<template>
<div class="modal" v-if="show" @click.self="close">
<div class="modal-content">
<img :src="imageUrl" alt="Preview" />
<button @click="close">Close</button>
</div>
</div>
</template>
<script>
export default {
props: {
show: Boolean,
imageUrl: String
},
methods: {
close() {
this.$emit('close');
}
}
};
</script>
<style>
.modal {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: rgba(0, 0, 0, 0.5);
display: flex;
justify-content: center;
align-items: center;
}
.modal-content {
background: white;
padding: 20px;
border-radius: 5px;
}
.modal-content img {
max-width: 80vw;
max-height: 80vh;
}
</style>
在父组件中使用
父组件中维护弹窗状态和当前图片 URL,通过点击事件触发弹窗显示。
<template>
<div>
<img
v-for="(img, index) in images"
:key="index"
:src="img.thumbnail"
@click="openModal(img.fullSize)"
/>
<ImageModal
:show="isModalVisible"
:imageUrl="currentImage"
@close="closeModal"
/>
</div>
</template>
<script>
import ImageModal from './ImageModal.vue';
export default {
components: { ImageModal },
data() {
return {
isModalVisible: false,
currentImage: '',
images: [
{ thumbnail: '/thumb1.jpg', fullSize: '/full1.jpg' },
{ thumbnail: '/thumb2.jpg', fullSize: '/full2.jpg' }
]
};
},
methods: {
openModal(imgUrl) {
this.currentImage = imgUrl;
this.isModalVisible = true;
},
closeModal() {
this.isModalVisible = false;
}
}
};
</script>
使用第三方库
对于更复杂的需求,可以使用现成的 Vue 图片预览库:
- vue-easy-lightbox:轻量级图片查看器
npm install vue-easy-lightbox
<template>
<button @click="showLightbox">View Images</button>
<vue-easy-lightbox
:visible="visible"
:imgs="imgs"
@hide="handleHide"
/>
</template>
<script>
import VueEasyLightbox from 'vue-easy-lightbox';
export default {
components: { VueEasyLightbox },
data() {
return {
visible: false,
imgs: ['/image1.jpg', '/image2.jpg']
};
},
methods: {
showLightbox() {
this.visible = true;
},
handleHide() {
this.visible = false;
}
}
};
</script>
- vue-image-lightbox:提供类似 Google 图片的浏览体验
npm install vue-image-lightbox
动画过渡效果
为弹窗添加 Vue 过渡动画,提升用户体验:
<template>
<transition name="fade">
<div class="modal" v-if="show">
<!-- 模态框内容 -->
</div>
</transition>
</template>
<style>
.fade-enter-active, .fade-leave-active {
transition: opacity 0.3s;
}
.fade-enter, .fade-leave-to {
opacity: 0;
}
</style>
响应式设计考虑
确保弹窗在不同设备上正常显示:
@media (max-width: 768px) {
.modal-content {
width: 95%;
padding: 10px;
}
.modal-content img {
max-width: 95%;
}
}
