How to: Get and Set the App's Navigation Bar Items

For some websites it may be useful to dynamically modify the apps' navigation bar items. You can achieve this with these JavaScript functions.

Using the JavaScript Functions

getNavigationBarItems

Use this function to get a list of objects representing all the navigation bar items that are currently being displayed.

<script>
    try {
        // returns a list of objects representing the navigation bar items
        let navigationBarItems = (await getNavigationBarItems())["navigationBarItems"];
    }
    catch (e) {
        // Can occur if:
        // - the app couldn't connect to the native code. Should be very unlikely.
        console.log(e);
    }
</script>
    

setNavigationBarItems

Use this function to modify the navigation bar items that should be displayed.

<script>
    try {
        // example for a navigation bar item object
        let newNavigationBarItem = {
            label: "Contact",
            action: {
                urlToRedirectTo: "https://webtoapp.design/contact",
                javascriptToExecute: null,
                elementToClickSelector: null,
                isFavoriteAction: false,
                isShareAction: false,
                isOpenExternallyAction: false,
                isSettingsAction: false
            },
            icon: {
                name: "list"
            },
        };

        // get the currently displayed navigation bar items
        let allNavigationBarItems = (await getNavigationBarItems())["navigationBarItems"];

        // add the new navigation bar item to the list of navigation bar items
        allNavigationBarItems.push(newNavigationBarItem);

        // display the list of navigation bar items, including the new navigation bar item
        await setMenuItems(allNavigationBarItems);
    }
    catch (e) {
        // Can occur if:
        // - the app couldn't connect to the native code. Should be very unlikely.
        console.log(e);
    }
</script>
