// 需要刷新的时候 设置一个标记
sessionStorage.setItem('自定义字段名', 'submit') // submit随便是啥，有值能判断就行

beforeRouteEnter(to, from, next) {const mark = sessionStorage.getItem('自定义字段名')// 获取自定义字段// 从a页面回来并且没有标记，就不刷新，否则刷新if (from.name == 'a页面的name' && !mark) {next()} else {next((vm) => {if(from.name) {vm.刷新的函数()sessionStorage.removeItem('自定义字段名') //移除自定义字段}})}},

dialog遮罩层跳页未消失

<el-dialog title="标题" 
:visible.sync="show" 
:return-data="data"
:before-close="closeDialog" 
:close-on-click-modal="false" 
:modal-append-to-body='false' // 遮罩层只插入当前dialog的父元素，不在其他页显示
>
</el-dialog>
