This function simply writes a string to the textarea object one, upon being called by the onFocus event handler declared in its tag. |
| <form> <textarea rows="3" name="one" cols="20" onFocus="junk_(this.form)"></textarea> <input type="reset" value="Reset"> </form> |
onFocus calls the function junk_. This event handler refers to the state
of the cursor or mouse. Not to be confused with the focus() method which actually forces focus on an object. |

This script uses the focus() method to return the user
to an improperly completed form field. The form name is two, and contains the text elements one & two. By testing the user input against a predifined string "bingo", incorrect entries are returned to the incorrect field. |
This event works with select, text, text area objects & window objects.
