Trigger Standard Html5 Validation Form Without Using Submit Button

Are you looking to trigger standard HTML5 validation on a form without relying on the traditional submit button? You're not alone! Many developers want to enhance user experience by validating form fields dynamically without a full page reload. In this article, we'll walk through how you can achieve this using JavaScript in a straightforward manner.

The HTML5 form validation feature allows you to set specific validation criteria for form fields, such as required fields, numerical values, email formats, and more. Normally, this validation process gets triggered when the user clicks the submit button. However, you can also manually trigger the validation process through JavaScript without submitting the form.

To trigger standard HTML5 validation on a form dynamically, you can use the checkValidity() method and the reportValidity() method. The checkValidity() method checks if all the form fields are valid, while the reportValidity() method displays error messages if any fields are invalid.

Here's a simple example demonstrating how you can trigger HTML5 form validation without the submit button:

<button type="button">Validate Form</button>



    function validateForm() {
        var form = document.getElementById('myForm');
        
        if (form.checkValidity()) {
            alert('Form is valid! Submitting now...');
            // Your form submission logic here
        } else {
            form.reportValidity();
        }
    }

In the example above, we have a simple HTML form with a text input field that is required. The button inside the form has a type of "button" to prevent the default form submission behavior. When the button is clicked, the validateForm() function is called.

Inside the validateForm() function, we first get a reference to the form element using its ID. We then check if the form is valid by calling the checkValidity() method. If the form is valid, an alert message is shown indicating that the form is valid. You can replace the alert with your custom submission logic. If the form is invalid, the reportValidity() method displays error messages to the user.

By using this approach, you can create a more interactive and user-friendly experience for your form validation process. Remember to adapt this example based on the specific requirements of your project and customize it further to fit your needs.

I hope this article has provided you with a clear understanding of how to trigger standard HTML5 form validation without using the submit button. Happy coding!
