我有一个自定义指令，它是一个ng-modal窗口。我的问题是当我在代码中设置显示的一个字段（patientId）时，即使所有必填字段都为真，表单的$ valid也不会更新为true。当我通过UI更新patientid字段时，$ valid正确更新。由于在当前情况下禁用了相关字段，我不能依赖用户手动更新字段。作为一个快速修复，我使用$ error.required来禁用“保存”按钮但是想要以正确的方式执行它。

digest（）方法可能有所帮助：
将此函数添加到结尾，并在设置完所有内容后将值更改为范围的任何函数调用它：
function digest() {
if ( scope.$$phase !== '$apply' && scope.$$phase !== '$digest' ) {
scope.$digest();
}
}
您可以在Angulars网站上获取有关摘要功能的更多信息：
处理当前范围及其子项的所有观察者。 因为观察者的监听器可以改变模型，所以$ digest（）保持不变 打电话给观察者直到没有更多的听众开枪。

我希望这会有所帮助。

想出来。这是我使用的Autocomplete-alt指令的问题。更新到1.1.0并解决了它。
