<FORM> <INPUT TYPE="text" NAME="output" SIZE="30" onFocus="this.blur()"> </FORM>
This technique is very simple. When the user clicks inside the box (in order to enter text), the
onFocusevent handler is triggered. We then force the
blur()method in order to remove the focus from the box. In conclusion, whenever the text field receives focus, we immediately get rid of the focus so the user cannot enter any text.
Notice the use of the keyword
this in the event handler code. When used in a form element's event handler, it references the element itself.
