Validation (Num. or Chars)

JavaScriptSource Staff Sep 9, 2000
Validates an input field to make sure that only a number or character is entered. If you enter a number or a letter everything you can continue on. But, try entering another value like an exclamation point (!), an ampersand (&), or a dollar sign ($) and see what happens. It even highlights the incorrect entry field for you. Nice!

The JavaScript Source: Forms: Validation (Num. or Chars)

Simply click inside the window below, use your cursor to highlight the script, and copy (type Control-c or Apple-c) the script into a new file in your text editor (such as Note Pad or Simple Text) and save (Control-s or Apple-s). The script is yours!!!
