我是角度为2的ng-bootstrap库;特别是我在看:Components as content。我试图将示例代码合并到我的项目中,但收效甚微。我从浏览器调试器得到的错误是
没有NgbModal的提供者,我在示例代码中没有看到任何内容。我不知道在哪里可以设置一个角度2项目来悲伤地演示。我想做的就是拿出他们的示例代码并将其实现到modile.component.ts
将使用app.component.ts
和import { Component, NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { JsonpModule } from '@angular/http';
import { NgbModule } from '@ng-bootstrap/ng-bootstrap';
import { AppComponent } from './app.component';
import { NgbdModalComponent, NgbdModalContent } from './modal.component';
@NgModule({
imports: [
BrowserModule,
FormsModule
],
declarations: [
AppComponent,
NgbdModalComponent, NgbdModalContent
],
entryComponents: [NgbdModalContent],
bootstrap: [ AppComponent ]
})
export class AppModule { }
文件生成的标准项目中。
app.module.ts
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'Tour of Heroes';
}
app.component.ts
<div class="container-fluid">

export class NgbdModalContent {

constructor(public activeModal: NgbActiveModal) {}
}
@Component({

})
export class NgbdModalComponent {
constructor(private modalService: NgbModal) {}
open() {
const modalRef = this.modalService.open(NgbdModalContent);
modalRef.componentInstance.name = 'World';
}
}
modal.component.ts
<p>You can pass an existing component as content of the modal window. In this case remember to add content component
as an <code>entryComponents</code> section of your <code>NgModule</code>.</p>
<button class="btn btn-lg btn-outline-primary" (click)="open()">Launch demo modal</button>

错误:没有NgbModal,错误上下文,未处理承诺拒绝的提供者:没有NgbModal的提供者。感谢您的反馈。

您必须将NgbModule
导入NgModule
的导入数组。
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
...
imports: [NgbModule.forRoot(), ...],
...
})
export class AppModule {
}

以防您使用延迟加载。将NgbModule导入进口数组也很重要。但这次不是像@Pengyy所说的那样,而是
create table c_order(
order_date TIMESTAMP not null DEFAULT CURRENT_TIMESTAMP,
order_id number,
customer_id number not null,
product_id number not null,
primary key (order_id),
foreign key (customer_id) references Customer(customer_id),
foreign key (product_id) references products(product_id)
);

尝试在组件上提供NgbActiveModal
providers: [
NgbActiveModal,
]
