View层
<template>
<div>
<div class="mask" v-if="showModal" @click="showModal=false"></div>
<div class="pop" v-if="showModal">
<button @click="showModal=false" class="btn">点击出现弹框</button>
</div>
<button @click="showModal=true" class="btn">点击出现弹框</button>
</div>
</template>
数据层：
<script>
export default {
data() {
return {
showModal: false
};
}
};
</script>
样式层：
<style scoped>
.mask {
background-color: #000;
opacity: 0.3;
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
z-index: 1
}
.pop {
background-color: #fff;
position: fixed;
top: 100px;
left: 300px;
width: calc(100% - 600px);
height:calc(100% - 200px);
z-index: 2
}
.btn {
background-color: #fff;
border-radius: 4px;
border: 1px solid blue;
padding: 4px 12px;
}
</style>
关键点：
1.mask层的层级（z-index）要比弹出的pop的层级低。
2.wow,写完啦，就是这么简单....

.pop {
background-color: #fff;
position: fixed;
top: 100px;
left: 300px;
width: calc(100% - 600px);
height:calc(100% - 200px);

.btn {
background-color: #fff;
border-radius: 4px;
border: 1px solid blue;
padding: 4px 12px;
}
</style>
扩展：按钮在父组件，弹框是一个子组件，会涉及到父子组件之间的传值。
