Javascript Question

Javascript capture key

I am trying to catpure the enter key from a textarea using javascript. The problem is that although I am able to find out that the "enter" key was pressed, I am not unable to avoid it from coming in the textarea. I dont want the enter key i.e. "\n" to be displayed in the text area.

Any suggestions on how to achieve that?

Thank you.

Answer

Try setting this function as the onKeyDown event for the text area:

ex: onkeydown="javascript:return fnIgnoreEnter(event);"

function fnIgnoreEnter(thisEvent) {
  if (thisEvent.keyCode == 13) { // enter key
    return false; // do nothing
  }
}
