Updated on June 19, For a more complete guideline when studying a project, we can always go to ebooks. Ebooks give you a structural and organized way to learn a new topic, and it is no different with AngularJS.
The best thing about ebooks these days however is that it can be heavily supplemented with practical exercises that can help you strengthen your grasp and understanding of certain aspects. The ebook carries the transcription of the video done by Ian Smith with relevant screenshots and the timestamp of when a topic comes up.
If you prefer some text to go along with the video, then this is the ebook to get.
A cookbook of sorts, Recipes is a highly comprehensive book that deals with learning Anuglar in an organized and easy to understand way. Each section carries problems, solutions and discussions that will help guide you through Angular effectively.
The code examples shown in the book are available in GitHub. There are also sections on how to use KarmaJS to test your applications, how to use Firebase, miscellaneous tricks and troubelshooting you can use. This function takes two parameters: the route name and the route definition object which in itself contains various details for a route.
We will use only two of those properties: the templateURL which is a relative location of the view file, starting from index.
You can even place the above code in the app. Please bear in mind that the scripting of angular- route and app. Beware that the files for the views should not be complete HTML files, they should only have the markup for the specific view. In the homepage. Angular gives us several built-in filters as well as an easy way to create our own.
Time to have a look at index. We will have to tell Angular in which part of the application it should be active.
You saw that when declaring the angular module we named it app. We will use Bootstrap to create them easily but also to make them look stylish. It is the route we specified when we used when function, only it has a hashbang before it.
But where is the app going to display the views we created? You may have noticed the "row" attribute I gave to the div containing the ng-view element. It is there for styling purposes only. To make the website look a little more fancy, you create a styling.
Such is the magic of AngularJS. Suppose a form with two fields, username and email and two buttons, one for reset and the other with a submit role. Line 12 declares clarifies that our form is attached to validationCtrl and yes, your guess is right, the script.
A typical client-side validation process contains error messages, for the cases of invalid email or blank input fields. To read more about form properties, refer to the official documentation.
Generally, this means that we partially want extra messages to be displayed in our webapp. Lines 16 and implement the validation in the AngularJS way.
We want our submit button to be disabled, while the form is invalid line AngularJS provides ng-disabled directive to make this feasible. Suppose there is a predefined acceptable username and email from the webapp and that this the purpose of the reset button: to turn our form to its acceptable format.
On the other hand, the submit has to check if the form contains the correct data. Suppose a homepage with two links and each one of them will redirect to a specified page. To get a better understanding of our concept, we ll here implement an inline navigation.
AngularJS provides the ngView directive to implement the fore-mentioned functionality. So, keeping in mind that our index. So, at this point we should have a complete homepage: index. In order to use ngRoute, we have to call the angular.
Same for the "second". Practically, this means, that if the client requests a route that isn;t defined in the when method, this method will be executed. Imagine this as a general if-else statement. Access the web app from your local server: Figure 3. To get into this, I chose a simple form concept, where the user is prompt to insert his username. This updates an informative message i. Their responsibility is to initialize the data that the View needs to display.
