Javascript 在Ionic中添加项目后未刷新ng列表
我正在创建我的第一个Ionic应用程序之一,这个应用程序用于跟踪你欠别人钱的人。我已经创建了一个页面,您可以在其中添加金额,添加金额后,将显示包含这些金额的ng列表 问题是,在向ng repeat用于填充列表的数组(name=amounts)添加项目后,在刷新页面之前,它不会显示已添加项目 守则: 显示金额概述的我的html页面:Javascript 在Ionic中添加项目后未刷新ng列表,javascript,angularjs,ionic-framework,Javascript,Angularjs,Ionic Framework,我正在创建我的第一个Ionic应用程序之一,这个应用程序用于跟踪你欠别人钱的人。我已经创建了一个页面,您可以在其中添加金额,添加金额后,将显示包含这些金额的ng列表 问题是,在向ng repeat用于填充列表的数组(name=amounts)添加项目后,在刷新页面之前,它不会显示已添加项目 守则: 显示金额概述的我的html页面: <ion-view style="" class=" " id="page2" title="Te ontvangen default page"> &l

有人知道为什么会发生这种情况吗?您应该使用
$scope.$apply()
或$scope.$applyAsync()代码>,在数据绑定之后
下面是上面的文档:
