#SONG LYRICS SHUFFLER
|
|
|
|
### INTRO TO ANGULARJS BASICS
|
|
|
|
#### App
|
|
|
|
You will make a static page that displays songs with the song title, author, year, and lyrics. For no really good reason other than to practise `ng-click` and execute controller functions, you will be able to shuffle the order of the lyrics by clicking a shuffle button, as well as hide/show the song by clicking on the title.
|
|
|
|
Ultimately, you can add new songs to the page.
|
|
|
|
Sample screenshot:
|
|
|
|
|
|
#### The app should:
|
|
- Display song titles, authors, years, and lyrics line by line
|
|
- Hide / show the song by clicking on the title (the title does not get hidden 'cos you still have to click on it to show the song again)
|
|
- Shuffle the lyrics by pressing a shuffle button
|
|
- Add a new song
|
|
- When entering lyrics, the user should separate the lines of lyrics with a comma. **HINT FOR LATER** when the form is submitted, the app could `split` the lines by comma for use in an array
|
|
|
|
#### Set up - you will need:
|
|
- `index.html`
|
|
- `app.js`
|
|
- `style.css` if you want to add some style
|
|
|
|
Server and database will be introduced tomorrow
|
|
|
|
|
|
#### Angular stuff you will probably want:
|
|
|
|
#####Display songs
|
|
- A link to Angular 1.5 from https://angularjs.org/
|
|
- module / `ng-app`
|
|
- controller / `ng-controller`
|
|
- `ng-repeat` ( you might want to include a `track by $index` in the directive params, but if you don't need to, then don't)
|
|
- `ng-click` (hint: you can pass in $index as a param)
|
|
- `ng-if` or alternatively, `ng-hide` and/or `ng-show`
|
|
- curlies `{{ }}`
|
|
|
|
#####Add a song
|
|
- a form with an `ng-submit`
|
|
- inputs that rout to `ng-model`s which could be inside a formdata object in the controller maybe.
|
|
|
|
|
|
Overall, you will need data and functions in your controller.
|
|
|
|
#####Sample data
|
|
|
|
```
|
|
this.songs = [
|
|
{

hidden: false
|
|
}
|
|
];
|
|
```
|
|
|
|
#####Shuffle function
|
|
Pass in an array and the shuffle function will randomize the order of the elements
|
|
|
|
```
|
|
function shuffle(a) {
|
|
var j, x, i;
|
|
for (i = a.length; i; i -= 1) {
|
|
j = Math.floor(Math.random() * i);
|
|
x = a[i - 1];
|
|
a[i - 1] = a[j];
|
|
a[j] = x;
|
|
}
|
|
return a;
|
|
}
|
|
```
