**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab.
|
||||
|
||||
**User Stories:**
|
||||
|
||||
1. You should have an `h1` element for the main title of the page.
|
||||
2. You should have two `section` elements.
|
||||
3. Inside the first `section` element, you should have an `h2` element for the title of the video playing.
|
||||
4. Below the `h2` element, you should have a `video` element with `controls` and `width` attributes. The `width` attribute should be set to `640`.
|
||||
5. Inside the `video` element, you should have a `source` element with a `src` attribute pointing to a video file and a `type` attribute.
|
||||
- You can use `https://cdn.freecodecamp.org/curriculum/labs/What is the map method and how does it work.mp4`.
|
||||
6. Inside the second `section` element, you should have an `h2` element for the title of the song playing.
|
||||
7. Below the `h2` element, you should have an `audio` element with the `controls` and `loop` attributes, and a `src` attribute that points to an audio file.
|
||||

# --hints--
|
||||
|
||||
You should have an `h1` element for the main title of the page.
|
||||
|
||||
```js
|
||||
const h1 = document.querySelector('h1');
|
||||
assert.exists(h1);
|
||||
```
|
||||
|
||||
Your `h1` should not be empty.
|
||||
|
||||
```js
|
||||
const h1 = document.querySelector('h1');
|
||||
assert.isNotEmpty(h1.textContent.trim());
|
||||
```
|
||||
|
||||
You should have only one `h1` element
|
||||
|
||||
```js
|
||||
assert.lengthOf(document.querySelectorAll('h1'), 1);
|
||||
```
|
||||
|
||||
You should have two `section` elements.
|
||||
|
||||
```js
|
||||
assert.lengthOf(document.querySelectorAll('section'), 2);
|
||||
|
||||
```
|
||||
|
||||
Inside the first `section` element, you should have an `h2` element for the title of the video playing.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section');
|
||||
const h2 = section?.querySelector('h2');
|
||||
assert.exists(h2);
|
||||
```
|
||||
|
||||
Below the `h2` element, you should have a `video` element.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section');
|
||||
const video = section?.querySelector('h2 + video');
|
||||
assert.exists(video);
|
||||
```
|
||||
|
||||
The `video` element should have a `controls` attribute.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section');
|
||||
const video = section?.querySelector('h2 + video');
|
||||
const controlsAttr = video.controls;
|
||||
assert.isTrue(controlsAttr);
|
||||
```
|
||||
|
||||
The `video` element should have a `width` attribute set to `640`.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section');
|
||||
const video = section?.querySelector('h2 + video');
|
||||
const widthAttr = video.getAttribute('width');
|
||||
assert.equal(widthAttr, '640');
|
||||
```
|
||||
|
||||
Inside the `video` element, you should have a `source` element.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section');
|
||||
const source = section?.querySelector('h2 + video > source');
|
||||
assert.exists(source);
|
||||
```
|
||||
|
||||
The `source` element should have a `src` attribute pointing to a video file.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section');
|
||||
const source = section?.querySelector('h2 + video > source');
|
||||
const srcAttr = source.getAttribute('src');
|
||||
assert.match(srcAttr, /\.(mp4|webm|ogg|avi|mov)$/i);
|
||||
```
|
||||
|
||||
The `source` element should have a `type` attribute
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section');
|
||||
const source = section?.querySelector('h2 + video > source');
|
||||
const typeAttr = source.getAttribute('type');
|
||||
assert.isNotEmpty(typeAttr);
|
||||
```
|
||||
|
||||
Inside the second `section` element, you should have an `h2` element for the title of the song playing.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section:nth-of-type(2)');
|
||||
const h2 = section?.querySelector('h2');
|
||||
assert.exists(h2);
|
||||
```
|
||||
|
||||
All your `h2` elements should contain some text.
|
||||
|
||||
```js
|
||||
const h2s = document.querySelectorAll('h2');
|
||||
assert.isNotEmpty(h2s);
|
||||
h2s.forEach((h2) => assert.isNotEmpty(h2.textContent.trim()));
|
||||
```
|
||||
|
||||
Below the `h2` element, you should have an `audio` element.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section:nth-of-type(2)');
|
||||
const audio = section?.querySelector('h2 + audio');
|
||||
assert.exists(audio);
|
||||
```
|
||||
|
||||
The `audio` element should have a `controls` attribute.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section:nth-of-type(2)');
|
||||
const audio = section?.querySelector('h2 + audio');
|
||||
const controlsAttr = audio.controls;
|
||||
assert.isTrue(controlsAttr);
|
||||
```
|
||||
|
||||
The `audio` element should have a `loop` attribute.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section:nth-of-type(2)');
|
||||
const audio = section?.querySelector('h2 + audio');
|
||||
const loopAttr = audio.loop;
|
||||
assert.isTrue(loopAttr);
|
||||
```
|
||||
|
||||
The `audio` element should have a `src` attribute pointing to an audio file.
|
||||
|
||||
```js
|
||||
const section = document.querySelector('section:nth-of-type(2)');
|
||||
const audio = section?.querySelector('h2 + audio');
|
||||
const srcAttr = audio.getAttribute('src');
|
||||
assert.match(srcAttr, /\.(mp3|wav|ogg|aac|flac)$/i);
|
||||
```
