Javascript 如何使用表单。$addControl()
我使用的是Angular 1.0.8。如何正确添加已编译的表单元素?我想这与如何使用$addControl有关 考虑这个例子: 在本例中添加select后,只有当输入“myInput”时,表单才有效,它不能识别附加select的“required”指令Javascript 如何使用表单。$addControl(),javascript,angularjs,Javascript,Angularjs,我使用的是Angular 1.0.8。如何正确添加已编译的表单元素?我想这与如何使用$addControl有关 考虑这个例子: 在本例中添加select后,只有当输入“myInput”时,表单才有效,它不能识别附加select的“required”指令 <div ng-app="pageModule" ng-controller="parentCtrl"> <script type="text/ng-template" id="myTemplate">

表单。$addControl()是不必要的。我更正了compile命令,现在附加的元素正在表单控制器中注册:
如果您不需要
$compile
您的html,您可以使用ng show
指令隐藏
,直到需要为止。请注意,它仍然是必需的
