function countWords(text) {
    var normalizedText = text.
        replace(/(\r\n|\n|\r)/gm, " ").
        replace(/^\s+|\s+$/g, "").
        replace(" ", " ");

    normalizedText = strip(normalizedText);

    var words = normalizedText.split(/\s+/);

    for (var wordIndex = words.length - 1; wordIndex >= 0; wordIndex--) {
        if (words[wordIndex].match(/^([\s\t\r\n]*)$/)) {
            words.splice(wordIndex, 1);
            }
        }

        return (words.length);
    }

If the page submits, wrap the fields in <form></form>

and have

document.querySelector("form").onsubmit=function() { return false }

in a script after it
