I want to validate the E mail Address as soon as it is entered in a text box and the focus is changed to some other place in my web page.
Description: A script that closely examines the content of a form box to ensure that the user entered a valid email address.
As web developers, we want to protect the information filled out in form fields.
Here is an example page that does all of this for you.
Text Box 1 is for single emails and Text Box 2 validates multiple emails.
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.
