vue中简单弹框dialog的实现方法

效果如下，dialog中内容自行添加

<template>
<div>
<div class="dialog-wrap">
 <div class="dialog-cover" v-if="isShow" @click="closeMyself"></div>
 <transition name="drop">
 <div class="dialog-content" v-if="isShow">
  <p class="dialog-close" @click="closeMyself">x</p>
  <slot>empty</slot>
 </div>
 </transition>
</div>
</div>
</template>

接收父组件传参isShow，并返回一个自定义事件on-close

<script>
export default {
props: {
 isShow: {
 type: Boolean,
 default: false
 }
},
data () {
 return {
 }
},
methods: {
 closeMyself () {
 this.$emit('on-close')
 }
}
}
</script>

<style scoped>
.drop-enter-active {
transition: all .5s ease;
}
.drop-leave-active {
transition: all .3s ease;
}
.drop-enter {
transform: translateY(-500px);
}
.drop-leave-active {
transform: translateY(-500px);
}
.dialog-wrap {
position: fixed;
width: 100％;
height: 100％;
}
.dialog-cover {
background: #000;
opacity: .3;
position: fixed;
z-index: 5;
top: 0;
left: 0;
width: 100％;
height: 100％;
}
.dialog-content {
width: 50％;
position: fixed;
max-height: 50％;
overflow: auto;
background: #fff;
top: 20％;
left: 50％;
margin-left: -25％;
z-index: 10;
border: 2px solid #464068;
padding: 2％;
line-height: 1.6;
}
.dialog-close {
position: absolute;
right: 5px;
top: 5px;
width: 20px;
height: 20px;
text-align: center;
cursor: pointer;
}
.dialog-close:hover {
color: #4fc08d;
}
</style>
