我试图制作它以便我可以在组件之间进行良好的拖放,但让Dragula设置推荐的方式意味着每个组件都有自己的Dragula副本。所以我不能在组件之间拖放。
我尝试使用UpgradeAdaptor让Dragula成为全球供应商,但可能这不是正确的方法。我是Angular的新手
以下是我希望重用的组件:
import {Component, Input, Inject} from "@angular/core";
import {Dragula, DragulaService} from "ng2-dragula/ng2-dragula";
@Component({
selector: "drag-container",
template: require("../templates/draggable/drag-container"),
directives: [Dragula],
viewProviders: [],
providers: []
})
export class DragContainer<T> {
@Input() items: Array<T>;
@Input() edit: boolean;
constructor(private dragulaService: DragulaService) { }
}
我试图让Dragula成为全球性的:
import {UpgradeAdapter} from "@angular/upgrade";
import {DragulaService} from "ng2-dragula/ng2-dragula";
export const adapter = new UpgradeAdapter();
window["foo"].coursesAdapter = adapter;
// Angular 2 services
adapter.addProvider(DragulaService);
// Angular 1 services we want to use in Angular 2 components
adapter.upgradeNg1Provider("$routeParams");
adapter.upgradeNg1Provider("translate");
adapter.upgradeNg1Provider("showError");
adapter.upgradeNg1Provider("$location");
现在,我仍然可以在组件中拖动和重新排序,但我无法在组件中移动它。他们有相同的包名。

保留在应用组件中:
directives: [Dragula],
encapsulation: ViewEncapsulation.None,
viewProviders: [DragulaService]
在子组件中,只需:
directives: [Dragula]
