Altering Existing Menu Links

It's possible to alter existing menu links for our needs. We can do this by implementing hook_deviceready():

/**
 * Implements hook_deviceready().
 */
function my_module_deviceready() {
  try {

    // Print menu links to console to inspect the JSON structure.
    console.log(drupalgap.menu_links);

    // Make alterations here...

    // For example, add a custom class name to the 401 page.
    drupalgap.menu_links['401'].options.attributes['class'] += ' my_custom_class ';

  }
  catch (error) { console.log('my_module_deviceready - ' + error); }
}

Add Icons to an Existing Menu Link

Say for example, we wanted to place icons on the node View and Edit local task menu tabs:

That can be done like so:

drupalgap.menu_links['node/%/view'].options.attributes['data-icon'] = 'eye';
drupalgap.menu_links['node/%/edit'].options.attributes['data-icon'] = 'edit';

Change a Page Callback Function to Render an Existing Page Differently

For example, we could override the page_callback function that is used to render the system's dashboard page.

/**
 * Implements hook_deviceready().
 */
function my_module_deviceready() {
  try {
    drupalgap.menu_links['dashboard'].page_callback = 'my_module_dashboard_page';
  }
  catch (error) { console.log('my_module_deviceready - ' + error); }
}

/**
 * My dashboard page.
 */
function my_module_dashboard_page() {
  try {
    var content = {};
    content['my_paragraph'] = {
      markup: '<p>Clean your dashboard!</p>'
    };
    return content;
  }
  catch (error) { console.log('my_module_dashboard_page - ' + error); }
}

Now if we visit the dashboard page, our custom page_callback will be used when rendering the page:

To figure out any particular paths that need to be modified, just use the console log function:

console.log(drupalgap.menu_links);
