Example of a validation hook code to check for duplicate URLs in a list of menu items.
async function run() {
// Initialize error flag
let error = false;
// Get the list of menu items from the content model data
const menuItems = contentModel.data.get('links');
// Iterate through each menu item
menuItems.forEach(function (menu, key) {
// Extract the URL from the current menu item
const url = menu.get('url');
// Check for duplicates by comparing URLs with other menu items
if ([...menuItems.entries()].some(([otherKey, otherMenu]) => key !== otherKey && otherMenu.get('url') === url)) {
// Set the error flag to true if a duplicate URL is found
error = true;
}
});
// If duplicates are found, return an error message
if (error) {
return {
level: 'error',
message: 'Duplicate URLs found in the list of menu items!'
};
}
}
// Execute the validation function and return the result
return run();
