我试图解决这个问题一段时间但没有运气。我正在阅读整个下午的例子，如this或this关于ng-repeat中的验证，但我找不到任何可以解释我的代码无效的原因。
我的表格包含ng-repeat中的字段，所有这些字段都使用必需的参数。
当我触发更新按钮时，验证无效。如果我有没有 ng-repeat 的相同表单，则验证弹出窗口会正常显示（如果某些内容与输入条件不匹配）。我使用过这段代码：
ng-click="contactForm.$valid && updateContact(contact)"
上面的代码似乎对使用ng-repeat的表单没有影响。 如果可能，我想获得HTML 5验证pop-up：
当我按下更新按钮时，在空的字段上（或者如果正则表达式与输入不匹配）。我不想让字段说明需要或禁用更新按钮，因为某些字段不正确。

从ng-form="contactForm"删除<div>并将ng-repeat="con in contact"包裹在<form name="contactForm"></form>元素中。
对于您的更新按钮，您可能想要添加ng-disabled="contactForm.$invalid"。
