如何处理输入字段以设置setCustomValidity？这没用:

js fiddle

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

最佳答案

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.');
