App.vue is as follows
< div id= "app" >
<Header />
<Menu />
<div>
<router-view/>
</div>< / div >
structure of Header.vue
<li><router-link to="/a">a</router-link></li>
<li><router-link to="/b">b</router-link></li>< / div >
structure of Menu.vue
<!-- aa -->
<ul>
<li>a1</li>
<li>a2</li>
</ul>
<!-- ba -->
<ul>
<li>b1</li>
<li>b2</li>
</ul>< / div >
want to click header navigation, jump to different pages, page a shows menu a, page b shows menu b. Could you tell me how to solve this problem?
when you detect a change in the route on the navigation page
make a conditional decision to change the menu
<div>
<li><router-link to="/a" active-class="active" exact>a</router-link></li>
<li><router-link to="/b" active-class="active">b</router-link></li>
</div> you can add css
exact for him to show
