for example, the navigation bar has two buttons with the following address:
www.xxx.com/page1/A.vue
www.xxx.com/page2/B.vue
at this time, there are secondary pages called A1.vue and B1.vue in An and B
www.xxx.com/page1/subpage1/A1.vue
www.xxx.com/page2/subpage2/B1.vue
.().
A1B1,page1page2,,;
is there any way to highlight a child page as soon as it is loaded?
