Angular弹出模态框的两种方式(3)

日期：2020-05-12 栏目：程序人生浏览：次

<div class="modal-dialog">
 <div class="modal-content">
  <div class="modal-header">
   <button type="button" class="close" (click)="close()" >×</button>
   <h4 class="modal-title">{{title}}</h4>
  </div>
  <div class="modal-body">
   这是confirm弹框
  </div>
  <div class="modal-footer">
   <button type="button" class="btn btn-primary" (click)="close()">取消</button>
   <button type="button" class="btn btn-default">确定</button>
  </div>
 </div>
</div>

confirm.component.ts创建模态框组件

import { Component } from '@angular/core';
import { DialogComponent, DialogService } from 'ngx-bootstrap-modal';
export interface ConfirmModel {
 title:string;
 message:any;
}
@Component({
 selector: 'confirm',
 templateUrl: './confirm.component.html',
 styleUrls: ['./confirm.component.css']
})
export class ConfirmComponent extends DialogComponent<ConfirmModel, boolean> implements ConfirmModel {
 title: string;
 message: any;
 constructor(dialogService: DialogService) {
 super(dialogService);
 }
 confirm() {
 // on click on confirm button we set dialog result as true,
 // ten we can get dialog result from caller code
 this.close(true);
 }
 cancel() {
 this.close(false);
 }
}

3.内置弹框

(1)demo目录

--------app.component.ts

--------app.component.html
--------app.module.ts

(2)demo代码

内置弹框也包括 alert confirm prompt 三种形态，都有一些内置的样式

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BootstrapModalModule } from 'ngx-bootstrap-modal';
import { ModalModule } from 'ngx-bootstrap/modal';
import { AppComponent } from './app.component';
@NgModule({
 declarations: [
 AppComponent
 ],
 imports: [
 BrowserModule,
 BootstrapModalModule,
 ModalModule.forRoot()
 ],
 providers: [],
 bootstrap: [AppComponent]
})
export class AppModule { }

app.component.html很简单，就一个按钮

<div class="container">
 <div class="row">
 <button type="button" class="btn btn-default" (click)="show()">内置</button>
 </div> 
</div>

app.component.ts很简单，连组件的布局都不用写，传入一些参数比如图标icon，大小size等

import { Component } from '@angular/core';
import { DialogService, BuiltInOptions } from "ngx-bootstrap-modal";
@Component({
 selector: 'app-root',
 templateUrl: './app.component.html',
 styleUrls: ['./app.component.css']
})
export class AppComponent {
 title = 'app';
 constructor(public dialogService: DialogService) {
 }
 show(){
  this.dialogService.show(<BuiltInOptions>{
   content: '保存成功',
   icon: 'success',
   size: 'sm',
   showCancelButton: false
  })
 }
}
