Client-Side Validation Via <cfform>
You’ve already seen how ColdFusion can dramatically simplify server-side validation by automatically generating code for you.

And the best part is that you already know the tags you need to make this work: they are <cfform> and <cfinput>.
Listing 13.5 contains login3.cfm, a slightly modified version of login2.cfm. Make that very slightly modified. Can you even see the change?
