### copyToClipboard
|
|
|
|
Copy a string to the clipboard. Only works as a result of user action (i.e. inside a `click` event listener).
|
|
|
|
Create a new `<textarea>` element, fill it with the supplied data and add it to the HTML document.
|
|
Use `Selection.getRangeAt()`to store the selected range (if any).
|
|
Use `document.execCommand('copy')` to copy to the clipboard.
|
|
Remove the `<textarea>` element from the HTML document.
|
|
Finally, use `Selection().addRange()` to recover the original selected range (if any).
|
|
|
|
```js
|
|
const copyToClipboard = str => {
|
|
const el = document.createElement('textarea');
|
|
el.value = str;
|
|
el.setAttribute('readonly', '');
|
|
el.style.position = 'absolute';
|
|
el.style.left = '-9999px';
|
|
document.body.appendChild(el);
|
|
const selected =
|
|
document.getSelection().rangeCount > 0 ? document.getSelection().getRangeAt(0) : false;
|
|
el.select();
|
|
document.execCommand('copy');
|
|
document.body.removeChild(el);
|
|
if (selected) {
|
|
document.getSelection().removeAllRanges();
|
|
document.getSelection().addRange(selected);
|
|
}
|
|
};
|
|
```
|
|
|
|
```js
|
|
copyToClipboard('Lorem ipsum'); // 'Lorem ipsum' copied to clipboard.
|
|
```
