Validating textarea using javascript

The only out-of-the-box feature is to make a field required.While this is useful, sometimes businesses want more control over what users should and should not enter into a form.The form NAME=NEWSLETTER is another problem, as W3C says I am unable to use attribute "NAME" in this location.I would like to keep the JS close to how it is now as I have a library to use this JS over and over again.I am not a Javascript guy more of a HTML/CSS guy and I can manipulate JS to suit my needs.I have tried to make this "snippet" of JS code an external file but receive multiple errors with the JS calling for the FORM NAME as it is not on the same page.

The code you provided works great, but when I add a small IF Statement code (as shown below) then stops working and it does not even show any simple alerts added along the code. (text Field.val().trim()) else ; //Check if the input is empty if (text Field && !
