Trouble getting clipboard content

Hello, I'm trying to find out a functional construct to parse clipboard text and parse it to webform fields.

Syntax like this doesn't work:

var clipBoard;
navigator.clipboard.readText().then(text => clipBoard = text); // <= marked by script editor as syntax error

I'm looking for a working form, ideas? TY

This is not an error, but rather an ambiguous statement. Simply enclose it in parentheses like text => (clipBoard = text) or in curly braces like text => { clipBoard = text }

Note, however, your code is likely incorrect if you expect the subsequent statements to access clipBoard variable. That's because the Promise runs asynchronously after your enclosing context has already completed. It's like a one-time event listener for load event. It happens in the future.

The modern approach is to use async/await syntax with Promise-like things:

(async () => {
  let clipBoard = await navigator.clipboard.readText(); 
  // use the variable here
})();
