Angular Nativescript+角度分段条不能路由到其他组件?
我尝试使用分段栏来可视化不同组件中的两种类型的表单,如果我移除带有组件布线的零件,一切正常,并且栏本身可视化,但对于布线零件,甚至栏也不可视化,只是空白 其中一个部件与另一个部件相似:Angular Nativescript+角度分段条不能路由到其他组件?,angular,angular2-routing,nativescript,Angular,Angular2 Routing,Nativescript,我尝试使用分段栏来可视化不同组件中的两种类型的表单,如果我移除带有组件布线的零件,一切正常,并且栏本身可视化,但对于布线零件,甚至栏也不可视化,只是空白 其中一个部件与另一个部件相似: <ScrollView> <StackLayout> <TextField [text]="first_name" hint="First Name" class="purplish label-marg"></TextField>

this.navItems = [];
this.navItems.push(this.createSegmentedBarItem("Employer Form"));

我用控制台日志尝试了一下,结果它进入了交换机和正确的机箱,但是路由出了问题。如果有人能帮我找到正确的方法,我会提前向大家表示感谢。我找到了解决问题的方法。过了一段时间,我意识到TabView是一种更好的方法,不管怎样,我尝试了TabView,在项目更改时发送路线,但它不起作用。因为基本上发生了什么: 一,。我呈现带有选项卡的页面 2.然后我尝试路由到另一个组件 三,。这混淆了nativescript,因为路由试图将整个页面更改为另一个页面,而TabView或SegmentedBar的概念则完全不同,它假设视图应该保留在范围内,换句话说,它应该附加到TabView,但它试图占据主导地位 因此,使用TabView的简单解决方案非常简单,可以将我的组件的组件/视图选择器放在TabView的视图中,如下所示:
<basictoolbar></basictoolbar>
<TabView #tabView >
<StackLayout *tabItem="{title:'Employer Form'}">
<employer-form></employer-form>
</StackLayout>
<StackLayout *tabItem="{title:'Employee Form'}">
<employee-form></employee-form>
</StackLayout>
</TabView>
