I need to validate a form using the browser with the required property. Only that there is a problem, my submit button is not on the form. It has to stay out, and when I click on it I call $('form[name="meu_form"]').submit() and when I do this it does not validate using the browser.

Example:

HTML

<!-- HTML -->
<form name="meu_form">
   Teste campo: <input type="text" name="teste" required />
   <br />
   <button type='submit'>Enviar que valida o required</button>
</form>

<button class='btnSubmit'>Enviar que não funciona a validação do required</button>

Javascript

//Javascript
$(function(){
    $('form[name="meu_form"]').submit(function () {
         alert('Aqui faço as chamadas ajax...');
    });

    $('.btnSubmit').click(function (){
        $('form[name="meu_form"]').submit();
    });
});

The problem occurs in the following scenario:

If I leave the input empty and click the button inside the form , it validates, if I click on the outside it just goes by. Is there a way to validate this using the same validation of HTML , or do I really have to validate at hand, or do not know, use a plugin for example jQuery Validator?

There is a checkValidity method that is part of the HTML5 API . With it you can make the browser check the element. Not the whole form, but at least the elements one by one.

So in your code you can:

$('.btnSubmit').click(function (){
    var form = $('form[name="meu_form"]');
    var input = form.find('input[name="teste"]').get();
    if (input.checkValidity()) form.submit();
    else alert('Erro!');
});

Associate the button with your form indicating a id to form and calling it in button as per the code below:

<form name="meu_form" id="myForm">
   Teste campo: <input type="text" name="teste" required />
   <br />
   <button type='submit'>Enviar que valida o required</button>
</form>

<button class='btnSubmit' form="myForm">Enviar que não funciona a validação do required</button>

I said, it's kind of like a game but it worked!

First I create the button inside the form with display none

After this I put the button outside and call the .click with jquery in the element that I put display none.

Follow the code below to see how it went:

HTML

<!-- HTML -->
<form name="meu_form">
   Teste campo: <input type="text" name="teste" required />
   <br />
   <button type='submit' class='btnOrig' style='display: none;'>Enviar que valida o required</button>
</form>

<button class='btnSubmit'>Enviar que não funciona a validação do required</button>

JavaScript

//Javascript
$(function(){
    $('form[name="meu_form"]').submit(function () {
        alert('Aqui faço as chamadas ajax...');

        return false;
    });

    $('.btnSubmit').click(function (){
        $('.btnOrig').click();
        //$('form[name="meu_form"]').submit();
    });
});

Note: I put an example in the JSFiddle link: link
