HTML5 – 如何设置setCustomValidity?

如何解决输入字段以设置setCustomValidity? 这是行不通的:

小提琴

$('#numberinput').val("").setCustomValidity('The two email addresses must match.'); 

使用jQuery您可以执行以下操作:

 $('#numberinput').get(0).setCustomValidity('The two email addresses must match.'); 

并不是:

 $('#numberinput').val("").setCustomValidity('The two email addresses must match.');
