[Javascript] Test or Identify Value of Submit Button's Assigned Value

[Flavio Gomes]

Hello Ron,


Maybe changing  your checkForm to something like

          function checkForm(pressedSubmit)   { ... }

then call it as

          <input type=submit onclick="checkForm(this.value)" name=action 
value=Inquire>
          <input type=submit onclick="checkForm(this.value)" name=action 
value=Update>

Or you could set a variable initiated with the default "value" of the 
submit, and when the user clicks the button (the submit) it changes the 
variable value to it's(button's) value.
