在vue中实现给每个页面顶部设置title

router.beforeEach((to,form,next) => {
window.document.title = to.meta.title == undefined?'默认标题':to.meta.title
next()
})

<el-tooltip class="item-tabs" effect="dark" :content="item.stationName" placement="bottom-start" slot="label">
      <span>{{item.stationName}}</span>
     </el-tooltip>

<div class="left">
    <el-tabs tab-position="left" class="flex tooltitle tabsClass" @tab-click="handleClick" >
    <el-tab-pane v-for="(item,index) in chargingStatusTitle" :key="index">
     <el-tooltip class="item-tabs" effect="dark" :content="item.stationName" placement="bottom-start" slot="label">
      <span>{{item.stationName}}</span>
     </el-tooltip>
     <div class="content" >
     </div>
    </el-tab-pane>
    </el-tabs >
 </div>
