by the way, I would like to ask a question that compares low. If there is user information in the project"s header navigation, how can its data be cached when switching navigation? I will get the data again every time.

query changes will not refresh the page, but you can determine whether the route has changed by monitoring. You can also use the component to guard beforeRouteUpdate. Specific usage: see the document, Baidu or Google;
cache data can be cached with a vuex, browser
the idea is: record the selected tab when you click navigation and append it to url, listen for the change of $route and set the navigation click status according to the tab parameter loadData of url when loadData, fallback.
export default {
data () {
return {
tab: 0
}
},
created () {
this.onRoute()
},
watch: {
'$route': 'onRoute'
},
onRoute () {
this.loadData()
},
pushRouter () {
//
var query = this.$route.query
var queryString = ''
for (let key in query) {
if (key !== 'tab') queryString += `&${key}=${query[key]}`
}
this.$router.replace(`/ url?${queryString}&tab=${this.tab}`)
},
/**
*
*/
loadData () {
this.$request({
url: ' url',
params: {
tab: this.tab
}
}).then((data) => {
console.log(data)
})
},
/**
*
*/
clickNavigation (tab) {
this.tab = tab
this.pushRouter()
}
