Fetches all images from within an element and puts them into an array
|
|
|
|
- Use `Element.prototype.getElementsByTagName()` to fetch all `<img>` elements inside the provided element, `Array.prototype.map()` to map every `src` attribute of their respective `<img>` element, then create a `Set` to eliminate duplicates and return the array.
|
|
|
|
```js
|
|
const getImages = (el, includeDuplicates = false) => {
|
|
const images = [...el.getElementsByTagName('img')].map(img => img.getAttribute('src'));
|
|
return includeDuplicates ? images : [...new Set(images)];
|
|
};
|
|
```
|
|
|
|
```js
|
|
getImages(document, true); // ['image1.jpg', 'image2.png', 'image1.png', '...']
|
|
getImages(document, false); // ['image1.jpg', 'image2.png', '...']
|
|
```
