Validating Ranges, Emails, and URLs with jQuery`s Validator Plug-in
In this fourth part of a seven-part series on the jQuery Validator plug-in, I explain how to use the “range,” “email” and “url” options provided for checking numeric ranges, URLs and email addresses. Using these arguments is an intuitive process that can be learned in a very short time.
Validating Ranges, Emails, and URLs with jQuery`s Validator Plug-in - Validating email addresses and URLs with the email and url options (Page 4 of 4 )
In reality, checking email addresses and URLs with the Validator plug-in is only a matter of specifying two additional options within the “validate()” method, called “email” and “url.” Since their usage is very intuitive, I don’t think that you’ll have any major problems understanding how they work. The examples below show how to work with these arguments. Pay close attention to them:
(example on using the ‘email’ option)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
There you have it. Now, you learned by means of a couple of basic examples how to validate email addresses and URLs using the handy “email” and “url” options. Of course, as you might have noticed, the first code sample will only check whether the string entered in the field named “email” is a well-formatted email address, and nothing else. Any further validation should always be performed on the web server.
On the other hand, the last example will also check for a correctly-formatted URL, but it won’t verify that the URL really exists. Again, more strict checking procedures should be delegated to a server-side scripting language.
Well, at this point you should be armed with the proper background to start using the Validator plug-in for checking numeric ranges, as well as for valid URLs and email addresses. As with other arguments provided by the plug-in, the best way to understand how they work is with lots of practice. So, go head and play with all of the code samples included in this tutorial. You’ll have a great time, that’s for sure!
Final thoughts
In this fourth part of the series, I explained how to use the “range,” “email” and “url” options provided by the Validator jQuery plug-in for checking numeric ranges, URLs and email addresses. As you saw previously, using these arguments is an extremely intuitive process that can be learned in a very short time.
In the next article, I’m going to explain how to use the plug-in for checking numeric values. Don’t miss it!
