I'm working on a simple login form, with two fields:

<form>
  <input type="email" name="email" required />
  <input type="password" name="password" required />
  <button type="submit">Log in</button>
</form>

For modern browsers, validation is automatically triggered.

However, if Javascript is available, I want to take over the html5 form validation, and handle everything myself.

I want to validate automatically 'onblur' (only the affected field) and I want to validate all fields when 'submit' is clicked.

The onblur events work fine, however.. When 'submit' is pressed, the standard 'submit' event is not triggered. However, an 'invalid' event is triggered; but only for the first invalid event.

What's a nice way to tell the browser to ignore all HTML5-related validation, and take over the entire process?

Please be advised that — even though some browsers may support the attribute novalidate on INPUT elements — the HTML code does not validate.

According to documentation there is no such attribute. Only the FORM element may contain the novalidate attribute.

• https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form
• https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input
• http://www.w3.org/TR/html5/forms.html#the-form-element
• http://www.w3.org/TR/html5/forms.html#the-input-element

This answer is incorrect. Please see willydee's answer.

Simple, just add the novalidate property to any element you don't want the browser to validate, like so:

<form>
  <input type="email" name="email" required novalidate />
  <input type="password" name="password" required />
  <button type="submit">Log in</button>
</form>

$('input[novalidate]').attr('novalidate', 'novalidate');

Another option if you are using jQuery for example is to remove the attribute.

$("input[required],select[required],textarea[required]").removeAttr('required');

Maybe you can use javascript to transform all "required" attributes into "data-required" for you can handle them with javascript and to override html5 form validation with your own handler

If you want to conditional HTML5 validation operation.

My condition is that I want to stop validation if user want to save there data but when its want to send form I want to validate.

<button name="btn_act" value="Submit" type="submit" class="btn">Submit</button>
<button name="btn_act" value="save" type="submit" class="btn">Save</button>

$(document).on('click','[name="btn_act"]',function(){

        var $form = $(this).closest('form');
        //console.log($form);
        if(this.value === 'save')
            $form[0].noValidate = true;
        else
            $form[0].noValidate = false;
        //$form.data('validator').cancelSubmit = true;
        //$form.submit();
    });
