Creates an element from a string (without appending it to the document).
|
|
If the given string contains multiple elements, only the first one will be returned.
|
|
|
|
- Use `document.createElement()` to create a new element.
|
|
- Set its `innerHTML` to the string supplied as the argument.
|
|
- Use `ParentNode.firstElementChild` to return the element version of the string.
|
|
|
|
```js
|
|
const createElement = str => {
|
|
const el = document.createElement('div');
|
|
el.innerHTML = str;
|
|
return el.firstElementChild;
|
|
};
|
|
```
|
|
|
|
```js
|
|
const el = createElement(
|
|
`<div class="container">
|
|
<p>Hello!</p>
|
|
</div>`
|
|
);
|
|
console.log(el.className); // 'container'
|
|
```
