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
<div class="container"> <div class="row"> <button type="button" class="btn btn-primary" (click)="showAlert()">alert模态框</button> </div> </div>
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
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" (click)="close()" >×</button>
<h5 class="modal-title">{{title}}</h5>
</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.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, T1> 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 DialogComponent<AlertModel, null> implements 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
<div class="container"> <div class="row"> <button type="button" class="btn btn-primary" (click)="showConfirm()">modal模态框</button> </div> </div>
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
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" (click)="close()" >×</button>
<h5 class="modal-title">{{title}}</h5>
</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
})
}
}
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<any>){//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
<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> <!--第二种弹出方法的组件--> <template #Template> <div class="modal-header tips-modal-header"> <h5 class="modal-title pull-left">第二种模态框</h5> <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>
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
