javascript - Why should I use novalidate rather than deleting validation tags? -


it's easy find answers novalidate attribute in html5.
in angular.js we teached should use it, because angular.js should validation.
why not delete validation tags instead?

example:

<form novalidate>   <input type=number name=num step=5> </form>

here disable build in step=5 order novalidate.
why should write both when don't want have that?

isn't better approach?:

<form>   <input type=number name=num> </form>

so why use novalidation field @ all?

if don't add attribute. there 2 validation 1 browser angular

refer below url html5 validation do. http://www.the-art-of-web.com/html/html5-form-validation/

novalidate: specifies element represents form not meant validated browser during form submission.

there 1 more attribute called ** example: below html form without novalidate attribute.

<form action="demo_form.php"> e-mail: <input type="email" name="user_email" required="true"> <input type="submit"> </form>

if submit below form, below browser inbuilt feature validate field.
