在 Ionic 2 中，如何创建使用 Ionic 组件的自定义指令?

2022-01-13 00:00:00 javascript ionic2

创建一个基本指令很简单:

Creating a basic directive is simple:

import {Component} from 'angular2/core';

@Component({
    selector: 'my-component',
    template: '<div>Hello!</div>'
})
export class MyComponent {
    constructor() {

    }
}

这按预期工作.但是，如果我想在我的指令中使用 Ionic 组件，事情就会爆炸.

This works as expected. However, if I want to use Ionic components in my directive things blow up.

import {Component} from 'angular2/core';

@Component({
    selector: 'my-component',
    template: '<ion-list><ion-item>I am an item</ion-item></ion-list>'
})
export class MyComponent {
    constructor() {

    }
}

指令已渲染，但 Ionic 组件未转换，因此无法正常查看/工作.

The directive is rendered, but Ionic components are not transformed, and so wont look/work properly.

我找不到这方面的任何例子.我该怎么做?

I can't find any examples on this. How should I do this?

推荐答案

找到答案 这里:

您必须导入 Ionic 组件并将它们注册为'指令'

You have to import the Ionic components and register them as 'directives'

所以我的第二个例子变成了:

So my second example becomes:

import {Component} from 'angular2/core';
import {List, Item} from 'ionic/ionic';

@Component({
    selector: 'my-component',
    directives: [List, Item],
    template: '<ion-list><ion-item>I am an item</ion-item></ion-list>'
})
export class MyComponent {
    constructor() {

    }
}
