VUE组件中的 Drawer 抽屉实现代码

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 class=\"drawer\">
  <div :class=\"maskClass\" @click=\"closeByMask\"></div>
  <div :class=\"mainClass\" :style=\"mainStyle\" class=\"main\">
   <div class=\"drawer-head\">
    <span>{{ title }}</span>
    <span class=\"close-btn\" v-show=\"closable\" @click=\"closeByButton\">X</span>
   </div>
   <div class=\"drawer-body\">
    <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 class=\"box\">
    <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>
