How to have a textarea to keep scrolled to the bottom when updated

Question

My problem is a bit off the cuff here, so I\'ll try to explain this best I can.

I have a text area, having css of #object{overflow:hidden;resize:none;}.

Answer 1

function checkTextareaHeight(){
   var textarea = document.getElementById("yourTextArea");
   if(textarea.selectionStart == textarea.selectionEnd) {
      textarea.scrollTop = textarea.scrollHeight;
   }
}

Call this function every time when the contents of the textarea are changed. If you cannot edit the external influence, periodically activate this function using setInterval.
