javascript - In reactJS, how to copy text to clipboard?

#short

#clipboard
I'm using ReactJS and when a user clicks a link I want to copy some text to the clipboard.
I am using Chrome 52 and I do not need to support any other browsers.
I can't see why this code does not result in the data being copied to the clipboard. (the origin of the code snippet is from a Reddit post).
Am I doing this wrong? Can anyone suggest is there a "correct" way to implement copy to clipboard using reactjs?
copyToClipboard = (text) = {
console.log('text', text)
var textField = document.createElement('textarea')
textField.innerText = text
document.body.appendChild(textField)
textField.select()
document.execCommand('copy')
textField.remove()
}
