javascript-jQuery执行本机浏览器验证

如何使用jquery / javascript执行本机浏览器表单验证,就像用户尝试提交表单一样？

<form id="myform">
    <input type="text" name="myinput" required />
    <input type="email" name="myemail" required />
</form>

<div id="externalcheck">click to validate</div>

<script type="text/javascript">
   $("#externalcheck").click(function(){
     // how to run html5 browser's validation ?
   });
</scrpipt>

解决方法:

我的ajax示例.

var $form = $('form');

$form.find(':submit').on('click', function (evt) {
    // If the validation fails, return true and the form is processed as standard
    if($form[0].checkValidity() === false) {
      return true;
    }

    evt.preventDefault();

    $.post('/', $form.serialize(), function (response) {
        // Handling the response
    })
})
