And to add to what M. Watney said, you don't need the '#' when you call document.getElementById(), so instead of document.getElementById("#demo") call it like this document.getElementById("demo") And to display the textarea text length, use this alert(mytext.value.length) You missed the `value` attribute there.

amir, it's because the JS part gets loaded before the html window and hence it cannot find the html element. Put your code inside a function which will be called once the html window gets loaded. window.onload =function () { //your JS code goes here }is And by the next time consider giving a link to your question rather than posting the entire code over here.
