javascript angularjs validation

Javascript 通过<；更新值时，输入隐藏时ng无效不触发；按钮>；ng点击,javascript,angularjs,validation,Javascript,Angularjs,Validation,我对AngularJS是新手。我有一个简单的表单，如果所有必需的字段都有效，那么submit按钮将启用。如果我在方框中输入贷款金额，则会将类别ng valid添加到此输入中但是，在第二个字段上，我使用按钮通过单击更新隐藏字段的值。这会起作用，值会在单击时更新，但是该类仍然无效，并且“提交”按钮被禁用。我猜这与Angular有关，因为我不知道它已经更新了，但我无法找到解决方案。如果有任何帮助，我将不胜感激 <body ng-app="validationApp" ng-controller
