我对Angular4相当陌生。我一直致力于Angular 1.5.x的开发,现在将角度4中的相同应用程序转换为ngUpgrade
混合方法。 我在我的混合应用程序中使用ngx-bootstrap
模态组件来取代现有的模态服务。如何在打开的模态组件中访问`BsModalRef`?
我在下面的指南ngx-bootstrap-modal with service中发现了一些问题。
有问题,这种说法If you passed a component to .show() you can get access to opened modal by injecting BsModalRef
我这里复制同样的例子,
export class ModalContentComponent {
public title: string;
public list: any[] = [];
constructor(public bsModalRef: BsModalRef) {} // How do you get bsModalRef here
}
我尝试运行这个例子,但在开模我从来没有得到bsModalRef
。
我也尝试通过bsModalRef
到content
,但它使用一种模式,并且无法与嵌套模式一起使用。
有没有其他方法可以通过bsModalRef
在ModalContentComponent
?
在这里找到完整的例子,
import { Component } from '@angular/core';
import { BsModalService } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/modal-options.class';
@Component({
selector: 'demo-modal-service-component',
templateUrl: './service-component.html'
})
export class DemoModalServiceFromComponent {
bsModalRef: BsModalRef;
constructor(private modalService: BsModalService) {}
public openModalWithComponent() {
let list = ['Open a modal with component', 'Pass your data', 'Do something else', '...'];
this.bsModalRef = this.modalService.show(ModalContentComponent);
this.bsModalRef.content.title = 'Modal with component';
this.bsModalRef.content.list = list;
setTimeout(() => {
list.push('PROFIT!!!');
}, 2000);
}
}
/* This is a component which we pass in modal*/
@Component({
selector: 'modal-content',
template: `
<div class="modal-header">
<h4 class="modal-title pull-left">{{title}}</h4>
<button type="button" class="close pull-right" aria-label="Close" (click)="bsModalRef.hide()">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<ul *ngIf="list.length">
<li *ngFor="let item of list">{{item}}</li>
</ul>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" (click)="bsModalRef.hide()">Close</button>
</div>
`
})
export class ModalContentComponent {
public title: string;
public list: any[] = [];
constructor(public bsModalRef: BsModalRef) {} // How do you get bsModalRef here
}
显示完整的代码,在那里你调用'modalService.show()'或更好的创建plunker –
@Maximus添加了完整的代码 –
好吧,你能指望'BsModalRef什么成分'应该指什么?你可以设置一个简单的笨蛋吗? –
