Navigator.clipboard é indefinido
ou can write an all-in-one wrapper function.
if in secure context (https) : use navigator clipboard api
if not : use the 'out of viewport hidden text area' trick
// return a promise
function copyToClipboard(textToCopy) {
// navigator clipboard api needs a secure context (https)
if (navigator.clipboard && window.isSecureContext) {
// navigator clipboard api method'
return navigator.clipboard.writeText(textToCopy);
} else {
// text area method
let textArea = document.createElement("textarea");
textArea.value = textToCopy;
// make the textarea out of viewport
textArea.style.position = "fixed";
textArea.style.left = "-999999px";
textArea.style.top = "-999999px";
document.body.appendChild(textArea);
textArea.focus();
textArea.select();
return new Promise((res, rej) => {
// here the magic happens
document.execCommand('copy') ? res() : rej();
textArea.remove();
});
}
}
use :
copyToClipboard("I'm going to the clipboard !")
.then(() => console.log('text copied !'))
.catch(() => console.log('error'));
