Now, we will get through a form validation example with JQuery.
Employing a jQuery plugin to confirm forms serves a lot of objectives. It provides you additional skills like displaying custom error messages and incorporating conditional logic to form validation.
A validation library may also enable you to add validation to your HTML forms with minimal or no modifications to the markup. The requirements for validity can also be inserted, removed, or altered at any time quickly.
It’s possible to add a CDN hyperlink to get the documents of this plugin, without attached files into your site directory. Because this is a jQuery-based plugin, you’ll also have to put in a hyperlink into the jQuery library.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.19.0/jquery.validate.min.js"></script>
How to validate an HTML5 form with a jQuery plugin?
Here’s the form that we’ll validate:
<form id="basic-form" action="" method="post"> <p> <label for="name">Name <span>(required, at least 3 characters)</span></label> <input id="name" name="name" minlength="3" type="text" required> </p> <p> <label for="email">E-Mail <span>(required)</span></label> <input id="email" type="email" name="email" required> </p> <p> <input class="submit" type="submit" value="SUBMIT"> </p> </form>
$(record ).ready(function() $("#basic-type").validate(); );
The library attempts to be as user-friendly as you can by merely showing error messages when they’re necessary. But if you try to move to the email field after entering one character in the title field, you will get an error message regarding inputting three or more characters.
The error messages are injected in the DOM using the label element. All of these have an error course. Therefore it’s easy to employ your own styling with CSS. The same is true for invalid inputs, which also get an error class added to them.
