@丶JavaScript Do you mean changing the current page from a button inside pages? You’ll need to pass a prop function to modify your page variable or emit an event to do it.

@Fran-Diox Do u mean add a prop function in ons-tabbar to change current page?

[Fran Diox]

@丶JavaScript said:

<component :is=“page” :set-page="() => showPage(…)"></component>

<component :is=“page” @page=“showPage(…)”></component>

You pass props or event handler to the page components so you can communicate with them.
