Question

关于为什么https://codepen.io/anon/pen/qVbjGa：

的任何想法

<form>
    <input type="text" name="formField" title="Password must be at least eight characters in length, contain at least one capital letter, one number, and one special character." 
           pattern="\A(?=.*[a-z])(?=.*[A-Z])(?=.*[\W_])(?=.*[\d]).{8,}\z" required />
    <input type="submit" value="Submit" />
</form>

不会工作而http://rubular.com/r/9oIgojECMf会吗？
