因为项目中用的是 element-ui 框架，而这个框架并没有抽屉组件，所以自己实现一个，具体代码如下：
drawer.vue
<template> <div> <div :class="maskClass" @click="closeByMask"></div> <div :class="mainClass" :style="mainStyle"> <div> <span>{{ title }}</span> <span v-show="closable" @click="closeByButton">X</span> </div> <div> <slot/> </div> </div> </div> </template> <script> export default { props: { // 是否打开 display: { type: Boolean }, // 标题 title: { type: String, default: '标题' }, // 是否显示关闭按钮 closable: { type: Boolean, default: true }, // 是否显示遮罩 mask: { type: Boolean, default: true }, // 是否点击遮罩关闭 maskClosable: { type: Boolean, default: true }, // 宽度 width: { type: String, default: '400px' }, // 是否在父级元素中打开 inner: { type: Boolean, default: false } }, computed: { maskClass: function () { return { 'mask-show': (this.mask && this.display), 'mask-hide': !(this.mask && this.display), 'inner': this.inner } }, mainClass: function () { return { 'main-show': this.display, 'main-hide': !this.display, 'inner': this.inner } }, mainStyle: function () { return { width: this.width, right: this.display ? '0' : `-${this.width}`, borderLeft: this.mask ? 'none' : '1px solid #eee' } } }, mounted () { if (this.inner) { let box = this.$el.parentNode box.style.position = 'relative' } }, methods: { closeByMask () { this.maskClosable && this.$emit('update:display', false) }, closeByButton () { this.$emit('update:display', false) } } } </script> <style lang="scss" scoped> .drawer { /* 遮罩 */ .mask-show { position: fixed; top: 0; left: 0; width: 100%; height: 100%; z-index: 10; background-color: rgba(0,0,0,.5); opacity: 1; transition: opacity .5s; } .mask-hide { opacity: 0; transition: opacity .5s; } /* 滑块 */ .main { position: fixed; z-index: 10; top: 0; height: 100%; background: #fff; transition: all 0.5s; } .main-show { opacity: 1; } .main-hide { opacity: 0; } /* 某个元素内部显示 */ .inner { position: absolute; } /* 其他样式 */ .drawer-head { display: flex; justify-content: space-between; height: 45px; line-height: 45px; padding: 0 15px; font-size: 14px; font-weight: bold; border-bottom: 1px solid #eee; .close-btn { display: inline-block; cursor: pointer; height: 100%; padding-left: 20px; } } .drawer-body { font-size: 14px; padding: 15px; } } </style>
组件具体使用如下：
<template> <div> <el-button type="primary" @click="display = true">打开抽屉</el-button> <drawer title="我是一个抽屉组件" :display.sync="display" :inner="true" :width="drawerWidth" :mask="false"> 1. Hello, world! 2. Do you like it? </drawer> </div> </template> <script> import drawer from '@/components/drawer/drawer' export default { components: { drawer }, data () { return { display: false, drawerWidth: '500px' } } } </script>
