	emailAdEmailCheck

Description:

A script that closely examines the content of a form box to ensure that the user entered a valid email address. If not, the form submition is canceled, and the surfer prompted to re-enter a valid address. The script makes the following assumptions regarding what a valid email address is:

-Contains a least one character procedding the "@"
-Contains a "@" following the procedding character(s)
-Contains at least one character following the "@", followed by a dot (.), followed by either a two character or three character string (a two character country code or the standard three character US code, such as com, edu etc)

Note that this script requires NS 4+ or IE 4+ to function- all other browsers will simply not participate in the form validation process.

Example:

Directions:

Simply cut and paste the below code into the <body> section of your page. It
contains a form with one box that is checked for "email validity". You can add in more form elements into the form, as you would with any other form.

<form name="validation" onSubmit="return checkbae()"> Please input a valid email address:<br /> <input type="text" size=18 name="emailcheck"> <input type="submit" value="Submit"> </form> <script language="JavaScript1.2"> var testresults function checkemail(){ var str=document.validation.emailcheck.value var filter=/^([w-]+(?:.[w-]+)*)@((?:[w-]+.)*w[w-]{0,66}).([a-z]{2,6}(?:.[a-z]{2})?)$/i if (filter.test(str)) testresults=true else{ alert("Please input a valid email address!") testresults=false } return (testresults) } </script> <script> function checkbae(){ if (document.layers||document.getElementById||document.all) return checkemail() else return true } </script>
