如何将特定的绑定传递给Angular 1.5中的组件路由器带来的ng-outlet组件? [英] How do I pass specific bindings to ng-outlet components brought in by the component router in Angular 1.5?

问题描述

我希望能够将参数传递给ng-outlet带来的子组件.但是我不确定该怎么做.

I'd like to be able to pass parameters to child components brought in with ng-outlet. But I'm not sure how to do it.

这是我的组件绑定的示例:

Here's an example of my component bindings:

app.component('profile', {
  bindings: {
    section: '=',
    currentUser: '<'
  },
...

通常我会这样调用:

<profile section="$ctrl.bio" current-user="$ctrl.selectedUser"></profile>

但是我有这个:

<ng-outlet></ng-outlet>

还有一个将配置文件传入的路由器.

And a router that passes the profile in.

 $routeConfig: [
        { path: '/Profile/:id', name: 'Profile', component: 'profile' }]

那么，如何将其他必需的绑定(可能是无法编码为URL的绑定)传递给该组件呢?

So how the blazes do I pass other essential bindings, perhaps bindings that can't be encoded into the URL, to this component??

谢谢，非常感谢您的帮助

Thanks, help is very much appreciated

我被要求提供一个我想做的更具体的例子.

我认为概念上的问题很明确，但是在一个特殊情况下，传递路径参数显然不足.在我的应用程序组件级别说，我有一个事件回调函数onDeleteItem(id)

I thought the conceptual issue was fairly clear, but here's a particular case where passing route parameters is clearly insufficient. Say at my App component level I have an event callback function, onDeleteItem(id)

我如何复制

bindings: {
    onDeleteItem: "&"
}

...

<some-component on-delete-item="$ctrl.onDeleteItem(id)"></some-component>

带有ng-outlet?

with an ng-outlet?

推荐答案

我查看了文档，并在路由器中使用的组件之一中看到了这一点

I looked on the docs and saw this for one of the components used in the router

bindings: { $router: '<' }

所以我一直在想如果绑定可以被填充，那为什么我们不能传递其他绑定的数据，但是我仔细查看了组件路由器的来源，实际上我没有找到一种方法.这样传递数据.这是因为在这里看起来它是特殊处理的传入$ router ，但是我不认为此后会修改模板:

So I was thinking well if that binding can get filled in, then why can't we pass data for the other bindings, but I looked through the source of the component router, and I actually don't see a way to pass data that way. This is because here it looks like it's specially handling passing in the $router, but I don't think the template is modified after that:

activate(instruction) {
    ...
    this.controller.$$template = '<' + dashCase(componentName) + ' $router="::$$router"></' + dashCase(componentName) + '>';
    ...
};

不过，我会说，您应该能够使用

I will say though, you are supposed to be able to pass data through to the component using

$routeConfig: [
    { path: '/Profile/:id', name: 'Profile', component: 'profile', data: { item1: 'item1'} }]

，然后在构造函数中注入 RouteData 组件，但我认为这仅在角度2中使用，因为我没有在角度1路由器中看到它的实现.

and then injecting RouteData in the constructor of the component, but I think this is only in angular 2, because I didn't see implementation for it the in the angular 1 router.

因此，根据我所做的研究，我认为您无法做到，否则就很难.另外，与以下内容相关:如何将数据注入由路由器创建的Angular2组件和
