How to disable form validation using the novalidate attribute?

form validation

To submit the form directly without triggering the browser's default verification mechanism, use the novalidate property in HTML. This attribute is added to the

<form> tag, which can prevent the browser from automatically performing built-in verification checks. Even if there are verification fields such as required or type="email", the user can submit the form directly. For example:
. Note that novalidate will not remove the verification attribute, but will just skip the browser's automatic verification. Additionally, if you want to disable verification only for a certain submit button, you should use the formnovalidate property instead of the novelidate.

The default verification mechanism of submitting the form directly without triggering the browser is actually very simple. You only need to use one attribute in HTML: novalidate . This property can be added to the <form></form> tag and tell the browser to "Don't worry about me, I will handle the verification myself."

What is novalidate attribute?

novalidate is a Boolean property. When you write it in the <form></form> tag, the browser will not perform any built-in verification checks on the form. That is to say, even if you use required , type="email" or other input fields with verification function, the user can submit the form directly without being intercepted.

For example:

 <form novalidate>
  <input type="email" required>
  <button type="submit">Submit</button>
</form>

In this example, even if the mailbox format is wrong or the input is empty, clicking the submit button will directly send the request, and no warning or submission will be popped up.

Why do you need to disable form verification?

Sometimes we don't want the browser to automatically interfere with the user's operations, especially in the following situations:

  • Use JavaScript to customize verification logic;
  • Want to skip the verification process during the testing phase;
  • I want to use back-end verification uniformly to avoid double verification of front-end and back-end;
  • Or you just want the user to fill in some information and save it as a draft first.

At this time, adding novalidate can make the browser "shut up" and return the control to the developer.

How to use novalidate correctly?

It is very simple to use. Just add this attribute to the <form> tag, and there is no need to assign values. But a few small points should be paid attention to:

  • It only affects the current form;
  • It does not remove HTML5's verification properties (such as required ), but simply prevents the browser from automatically performing verification;
  • If you want to enable verification in some cases and disable in others, you can dynamically add or remove this property with JS.

For example:

 <form id="myForm" novalidate>
  <input type="text" required>
  <button type="submit">Submit</button>
</form>

<script>
  // Recover if (shouldValidate) {
    document.getElementById(&#39;myForm&#39;).removeAttribute(&#39;novalidate&#39;);
  }
</script>

The difference between formnovalidate

Be careful not to confuse novalidate and formnovalidate :

  • novalidate is written on <form> and acts on the entire form;
  • formnovalidate is written on <button type="submit"> or <input type="submit"> and is only valid for that specific submit button.

For example:

 <form>
  <input type="email" required>
  <button type="submit" formnovalidate>No verification submission</button>
  <button type="submit">Normal submission</button>
</form>

Clicking the first button will skip verification, while the second will trigger verification.

Basically that's it. Adding a property can control browser behavior, which is simple but practical, especially when you need to take over the verification process yourself.
