背景：vue项目中多个el-drawer抽屉组件嵌套官方自带遮罩层出现顺序混乱的bug
使用了官方自带类 :append-to-body=“true” :modal-append-to-body=“false” 都无法解决后
自己定义了一个组件，虽然简陋但是解决了问题

最终展示效果

解决方案

使用:modal="false"将官方自带遮罩层关闭，在将el-drawer设置背景色，实现效果与官方一至

组件调用源码

<jw-drawer @change="change_data" :withheader="true" v-if="dialogVisible" :drawer='dialogVisible'
            size="60%" :title="dialogtitle">
            
</jw-drawer>
