Angular两种模态框弹出方式

在开始我们的blog之前，我们要先安装ngx-bootstrap-modal

npm install ngx-bootstrap-modal --save

然后在index.html导入bootstrap样式表

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" rel="stylesheet">

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.module.ts

app.component.html创建一个可以弹出模态框的按钮

<div class="container">
  <div class="row">
    <button type="button" class="btn btn-primary" (click)="showAlert()">alert模态框button>
  div> 
div>

app.component.html

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!!!' });
    }
}

app.component.ts

detail.component.html编写alert弹框的布局

<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alert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>

detail.component.html

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 类，包含两个参数：
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 DialogComponentnull> implements AlertModel {
  title: string;
  message: string;
  constructor(dialogService: DialogService) {
    super(dialogService);
  }
}

detail.component.ts

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个  
import { BootstrapModalModule } 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.module.ts

app.component.html创建一个可以弹出模态框的按钮

<div class="container">
  <div class="row">
    <button type="button" class="btn btn-primary" (click)="showConfirm()">modal模态框button>
  div> 
div>

app.component.html

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) => {
                
            });
    }
}

app.component.ts

confirm.component.html编写confirm弹框的布局

<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.html

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 DialogComponentboolean> 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);
  }
}

confirm.component.ts

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.module.ts

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.html

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
      })
    }
}

app.component.ts

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.module.ts

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.ts

app.component.html

<div class="container">
  <div class="row">
    <button type="button" class="btn btn-success" (click)="showSecond(Template)">第二种弹出方式button>
  div> 
div>


<template #Template>
  <div class="modal-header tips-modal-header">
    <h4 class="modal-title pull-left">第二种模态框h4>
    <button type="button" class="close pull-right" aria-label="Close" (click)="modalRef.hide()">
      <span aria-hidden="true">×span>
    button>
  div>
  <div class="modal-body tips-modal-body">
    <div class="tips-contain"><span>第二种模态框弹出方式span>div>
  div>
  <div class="modal-footer">
      <button type="button" class="btn btn-default" (click)="modalRef.hide()">确定button>
      <button type="button" class="btn btn-default" (click)="modalRef.hide()">取消button>
  div>
template>

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
