我尝试将数据发送到自定义模态内容组件,因此我可以从任何其他组件调用它而不重复代码。我是Angular 2的新手,并且已经跟随"组件作为内容" ng-boostrap的演示以及"组件交互"在Angular文档中并没有找到一种方法来使这个工作或这个案例的例子。
我可以打开模态,但不能使用动态内容。我尝试了@Input
和变量方法但没有成功。我还在ModalService
中向提供商添加了app.module.ts
。这就是我用两种方法都行不通的方法:
page.component.html:
<a (click)="modal('message')">
<template ngbModalContainer><my-modal [data]="data"></my-modal></template>
page.component.ts:
import { Component } from '@angular/core'
import { NgbModal } from '@ng-bootstrap/ng-bootstrap'
import { ModalService } from '../helpers/modal.service'
import { ModalComponent } from '../helpers/modal.component'
@Component({
selector: 'app-page',
templateUrl: './page.component.html',
styleUrls: ['./page.component.scss'],
entryComponents: [ ModalComponent ]
})
export class PageComponent {
data = 'customData'
constructor (
private ngbModalService: NgbModal,
private modalService: ModalService
) { }
closeResult: string
modal(content) {
this.data = 'changedData'
this.modalService.newModal(content)
this.ngbModalService.open(ModalComponent).result.then((result) => {
this.closeResult = `Closed with: ${result}`
}, (reason) => {
this.closeResult = `Dismissed ${reason}`
});
}
}
modal.service.ts:
import { Injectable } from '@angular/core';
import { Subject } from 'rxjs/Subject';
@Injectable()
export class ModalService {
private modalSource = new Subject<string>()
modal$ = this.modalSource.asObservable()
newModal(content: string) {
this.modalSource.next(content)
}
}
modal.component.ts:
import { Component, Input, OnDestroy } from '@angular/core';
import { Subscription } from 'rxjs/Subscription';
import { ModalService } from './modal.service'
@Component({
selector: 'my-modal',
template: `
<div class="modal-body">
{{data}}
{{content}}
</div>
`
})
export class ModalComponent implements OnDestroy {
@Input() data: string
content = 'hello'
subscription: Subscription
constructor(
private modalService: ModalService
) {
this.subscription = modalService.modal$.subscribe(
content => {
this.content = content
});
}
ngOnDestroy() {
this.subscription.unsubscribe();
}
}
使用angular v2.1.0,angular-cli v1.0.0-beta.16,ng-bootstrap v1.0.0-alpha.8

我解决了!以下是如何做到这一点:
在组件中(从您打开模态的位置)执行以下操作:
const modalRef = this.modalService.open(ModalComponent);
modalRef.componentInstance.passedData= this.dataToPass;
modalRef.result.then(result => {
//do something with result
}
在模态组件(接收端)中:
export class ModalComponent {
passedData: typeOfData; // declare it!
someFunction() { // or some lifecycle hook
console.log(this.passedData) // and then, use it!
}
// rest of the ModalComponent
}

只需提供服务并将其注入VideoModalComponent
和PageComponent
,然后您就可以使用此服务进行通信。
有关详细信息和示例,请参阅https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#bidirectional-service。

以下是一些方法。
RewriteEngine on
RewriteCond %{REMOTE_ADDR} !**.**.**.*
RewriteRule !^maintenance/ http://www.website.co.uk/maintenance/ [R=302,L]
