本文主要介绍了Angular弹出模态框的两种方式,非常不错,具有参考借鉴价值,需要的朋友可以参考下,希望能帮助到大家。
在开始我们的blog之前,我们要先安装ngx-bootstrap-modal
npm install ngx-bootstrap-modal --save
不然我们的模态框效果会难看到你想吐
一、弹出方式一(此方法来自https://github.com/cipchk/ngx-bootstrap-modal)
1.alert弹框
(1)demo目录
--------app.component.ts
--------app.component.html
--------app.module.ts
--------detail(文件夹)
------------detail.component.ts
------------detail.component.html
(2)demo代码
app.module.ts导入必要的BootstrapModalModule 和ModalModule ,再注册它们
//app.module.ts import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; //这种模态框只需要导入下面这两个 import { BootstrapModalModule } from 'ngx-bootstrap-modal'; import { ModalModule } from 'ngx-bootstrap/modal'; import { AppComponent } from './app.component'; import { DetailComponent } from './detail/detail.component'; @NgModule({ declarations: [ AppComponent, DetailComponent ], imports: [ BrowserModule, BootstrapModalModule ], providers: [], entryComponents: [ DetailComponent ], bootstrap: [AppComponent] }) export class AppModule { }
app.component.html创建一个可以弹出模态框的按钮
app.component.ts编写这个按钮的动作showAlert()
import { Component } from '@angular/core'; import { DialogService } from "ngx-bootstrap-modal"; import { DetailComponent } from './detail/detail.component' @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'app'; constructor(public dialogService: DialogService) { } showAlert() { this.dialogService.addDialog(DetailComponent, { title: 'Alert title!', message: 'Alert message!!!' }); } }
detail.component.html编写alert弹框的布局
{{title}}
这是alert弹框
detail.component.ts创建模态框组件,我们需要创建一个组件,然后由 ngx-bootstrap-model 帮忙引导启动
对于这个组件需要继承 DialogComponent
T 外部传参给模态框的类型。
T1 模态框返回值类型。
因此,DialogService应该是DialogComponent的一个构造函数的参数。
import { Component } from '@angular/core'; import { DialogComponent, DialogService } from 'ngx-bootstrap-modal'; export interface AlertModel { title: string; message: string; } @Component({ selector: 'alert', templateUrl: './detail.component.html', styleUrls: ['./detail.component.css'] }) export class DetailComponent extends DialogComponentimplements AlertModel { title: string; message: string; constructor(dialogService: DialogService) { super(dialogService); } }
2.confirm弹框
(1)demo目录
--------app.component.ts
--------app.component.html
--------app.module.ts
--------confirm(文件夹)
------------confirm.component.ts
------------confirm.component.html
(2)demo代码
app.module.ts导入必要的BootstrapModalModule 和ModalModule ,再注册它们,这些都跟alert弹框一样,因为这些都是方法一的弹出方式
//app.module.ts import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; //这种模态框只需要导入下面这两个 import { BootstrapModalModule } from 'ngx-bootstrap-modal'; import { ModalModule } from 'ngx-bootstrap/modal'; import { AppComponent } from './app.component'; import { DetailComponent } from './detail/detail.component'; @NgModule({ declarations: [ AppComponent, DetailComponent ], imports: [ BrowserModule, BootstrapModalModule ], providers: [], entryComponents: [ DetailComponent ], bootstrap: [AppComponent] }) export class AppModule { }
app.component.html创建一个可以弹出模态框的按钮
app.component.ts编写这个按钮的动作showConfirm()
import { Component } from '@angular/core'; import { DialogService } from "ngx-bootstrap-modal"; import { ConfirmComponent } from './confirm/confirm.component' @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'app'; constructor(public dialogService: DialogService,private modalService: BsModalService) { } showConfirm() { this.dialogService.addDialog(ConfirmComponent, { title: 'Confirmation', message: 'bla bla' }) .subscribe((isConfirmed) => { }); } }
confirm.component.html编写confirm弹框的布局
{{title}}
这是confirm弹框
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 DialogComponentimplements 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
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({ content: '保存成功', icon: 'success', size: 'sm', showCancelButton: false }) } }
二、弹出方式二(此方法来自https://valor-software.com/ngx-bootstrap/#/modals)
还是跟上一种方法一样,先安装ngx-bootstrap-modal,然后导入bootstrap样式表
1.demo目录
--------app.component.ts
--------app.component.html
--------app.module.ts
2.demo代码
app.module.ts导入相应模块,并且注册它们
//app.module.ts import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { ModalModule } from 'ngx-bootstrap/modal'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, ModalModule.forRoot() ], providers: [], entryComponents: [ ], bootstrap: [AppComponent] }) export class AppModule { }
app.component.ts
import { Component,TemplateRef } from '@angular/core'; import { BsModalService } from 'ngx-bootstrap/modal'; import { BsModalRef } from 'ngx-bootstrap/modal/modal-options.class'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'app'; public modalRef: BsModalRef; constructor(private modalService: BsModalService) { } showSecond(template: TemplateRef){//传入的是一个组件 this.modalRef = this.modalService.show(template,{class: 'modal-lg'});//在这里通过BsModalService里面的show方法把它显示出来 }; }
app.component.html

三、最终效果
我们将上面所有的弹框全部写在一起,然后效果就是这样的
