manipulate elements found on another page

Yes this is possible. You will need to use Wix-Storage .

How would it work?

  1. Generating an Object which will hold all needed data to control your element from PAGE-A, on PAGE-B…
import {local} from 'wix-storage';

let data = {
  element: "elementIDhere",
  command: "show",
}

local.setItem("key1", data);

On PAGE-B you get the data and use it…

import {local} from 'wix-storage';

let data = JSON.parse(local.getItem("key1")); console.log(data);


$w.onReady(()=>{$w(`#${data.element}`)[data.command]();});
