Q:

Explain about AngularJS boot process.

Answer

When the page is loaded in the browser, following action takes place:


HTML document is loaded into the browser, and evaluated by the browser. AngularJS JavaScript file is loaded; the angular global object is created. Next, JavaScript which registers controller functions is executed.


AngularJS scans through the HTML to look for AngularJS applications and views. Once view is located, it then connects that view to the corresponding controller function.


Then, AngularJS executes the controller functions. It then renders the views with data from the model populated by the controller. The page is ready.

Q:

How do we create a DHTML drop-down menu?

Answer

- In order to create a DHTML drop down menu we need JavaScript API. The API (Application Programming Interface) consists of core set of cross-browser JavaScript functions to make DHTML programming easy and quick. This API enables moving and hiding page elements as well as acts as getter and setter of page elements attributes.


- Second we define on image object and off image object and string containing the URL of the "off" version.


- Then we create the menu items, label items and sub-menu items. If we wish we can use images also.


- Then we need to define our own global variables that will be used by the menu. Using global goes against oops design but makes sharing data easier.


- Create the menubar object, adding the menu labels and writing menubars.


- Create menu object, adding menu items and writing menus.
