Answer 1

You need to use JavaScript to attach an event listener to listen for the input event, then use the includes() method to check whether the substring is contained in the input. The method will return true if the substring is found, or false if not.

For example:

document.querySelector('input').addEventListener('input', event => {
  if (event.target.value.includes('DO NOT PEND')) {
    // trigger your label here
  }
})
