header組件寫到了App.vue中，在注冊登錄后加載header，但是在注冊，修改密碼等頁面中不需要header，如何合理巧妙的避免header的加載項目中采用根據(jù)路由判斷，v-if 隱藏掉header，但是笨重又不高效，有什么比較哦好的辦法<div id="app">     <HeaderBar v-if='this.$route.path!="/login"              && this.$route.path!="/register"             && this.$route.path!="/register/"             && this.$route.path!="/register/companyTwo"             && this.$route.path!="/register/companySuc"             && this.$route.path!="/login/"             && this.$route.path!="/login/quickLogin"             && this.$route.path!="/secondTe"             && this.$route.path!="/secondTeC"             && this.$route.path!="/threeSuc"             && this.$route.path!="/threeSucC"             && this.$route.path!="/findPwd"             && this.$route.path!="/problem"'>       </HeaderBar>       <router-view />  </div>
