title: Trouble adding an onkeypress event to a textbox outside of the input tag
body: <p>I need to add an event to a text box without modifying the input tag itself.  I created a function which will check to make sure only letters are entered and not allow numbers or symbols.  I have to code for this and it is functional... when inserted inside of the input tag, I am having trouble in adding this event elsewhere in my code.  Any help is much appreciated.</p>
  
  <p>Thanks in advance,</p>
