## Usage

```javascript
var execCopy = require('exec-copy')

button.addEventListener('click', function (e) {
  execCopy('this is copied text!!')
})
```

### Fallback

Some browser (e.g. Safari) doesnot have `execCommand('copy')`. For fallback, This library automatically open `window.prompt`.

Also you can overwrite fallback if you need.

```javascript
execCopy('this is copied text!!', function (str) {
  // do something when execCommand('copy') is not available
})
```
