Modal对话框

模态对话框。

何时使用

需要用户处理事务,又不希望跳转页面以致打断工作流程时,可以使用 Modal 在当前页面正中打开一个浮层,承载相应的操作。

另外当需要一个简洁的确认框询问用户时,可以使用精心封装好的 NzModalService.confirm() 等方法。

推荐使用加载Component的方式弹出Modal,这样弹出层的Component逻辑可以与外层Component完全隔离,并且做到可以随时复用,

在弹出层Component中可以通过依赖注入NzModalRef方式直接获取模态框的组件实例,用于控制在弹出层组件中控制模态框行为。

单独引入此组件

想要了解更多关于单独引入组件的内容,可以在快速上手页面进行查看。

  1. import { NzModalModule } from 'ng-zorro-antd/modal';

Modal对话框 - 图1

基本

第一个对话框。

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-modal-basic',
  4. template: `
  5. <button nz-button [nzType]="'primary'" (click)="showModal()"><span>Show Modal</span></button>
  6. <nz-modal [(nzVisible)]="isVisible" nzTitle="The first Modal" (nzOnCancel)="handleCancel()" (nzOnOk)="handleOk()">
  7. <p>Content one</p>
  8. <p>Content two</p>
  9. <p>Content three</p>
  10. </nz-modal>
  11. `
  12. })
  13. export class NzDemoModalBasicComponent {
  14. isVisible = false;
  15. constructor() {}
  16. showModal(): void {
  17. this.isVisible = true;
  18. }
  19. handleOk(): void {
  20. console.log('Button ok clicked!');
  21. this.isVisible = false;
  22. }
  23. handleCancel(): void {
  24. console.log('Button cancel clicked!');
  25. this.isVisible = false;
  26. }
  27. }

自定义页脚

更复杂的例子,自定义了页脚的按钮,点击提交后进入 loading 状态,完成后关闭。

不需要默认确定取消按钮时,你可以把 nzFooter 设为 null

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-modal-footer',
  4. template: `
  5. <button nz-button nzType="primary" (click)="showModal()">
  6. <span>Show Modal</span>
  7. </button>
  8. <nz-modal
  9. [(nzVisible)]="isVisible"
  10. [nzTitle]="modalTitle"
  11. [nzContent]="modalContent"
  12. [nzFooter]="modalFooter"
  13. (nzOnCancel)="handleCancel()"
  14. >
  15. <ng-template #modalTitle>
  16. Custom Modal Title
  17. </ng-template>
  18. <ng-template #modalContent>
  19. <p>Modal Content</p>
  20. <p>Modal Content</p>
  21. <p>Modal Content</p>
  22. <p>Modal Content</p>
  23. <p>Modal Content</p>
  24. </ng-template>
  25. <ng-template #modalFooter>
  26. <span>Modal Footer: </span>
  27. <button nz-button nzType="default" (click)="handleCancel()">Custom Callback</button>
  28. <button nz-button nzType="primary" (click)="handleOk()" [nzLoading]="isConfirmLoading">Custom Submit</button>
  29. </ng-template>
  30. </nz-modal>
  31. `
  32. })
  33. export class NzDemoModalFooterComponent {
  34. isVisible = false;
  35. isConfirmLoading = false;
  36. constructor() {}
  37. showModal(): void {
  38. this.isVisible = true;
  39. }
  40. handleOk(): void {
  41. this.isConfirmLoading = true;
  42. setTimeout(() => {
  43. this.isVisible = false;
  44. this.isConfirmLoading = false;
  45. }, 3000);
  46. }
  47. handleCancel(): void {
  48. this.isVisible = false;
  49. }
  50. }

确认对话框

使用 NzModalService.confirm() 可以快捷地弹出确认框。NzOnCancel/NzOnOk 返回 promise 可以延迟关闭

  1. import { Component } from '@angular/core';
  2. import { NzModalRef, NzModalService } from 'ng-zorro-antd';
  3. @Component({
  4. selector: 'nz-demo-modal-confirm-promise',
  5. template: `
  6. <button nz-button nzType="info" (click)="showConfirm()">Confirm</button>
  7. `
  8. })
  9. export class NzDemoModalConfirmPromiseComponent {
  10. confirmModal: NzModalRef; // For testing by now
  11. constructor(private modal: NzModalService) {}
  12. showConfirm(): void {
  13. this.confirmModal = this.modal.confirm({
  14. nzTitle: 'Do you Want to delete these items?',
  15. nzContent: 'When clicked the OK button, this dialog will be closed after 1 second',
  16. nzOnOk: () =>
  17. new Promise((resolve, reject) => {
  18. setTimeout(Math.random() > 0.5 ? resolve : reject, 1000);
  19. }).catch(() => console.log('Oops errors!'))
  20. });
  21. }
  22. }

国际化

设置 nzOkTextnzCancelText 以自定义按钮文字。

  1. import { Component } from '@angular/core';
  2. import { NzModalService } from 'ng-zorro-antd';
  3. @Component({
  4. selector: 'nz-demo-modal-locale',
  5. template: `
  6. <div>
  7. <button nz-button nzType="primary" (click)="showModal()">Modal</button>
  8. <nz-modal
  9. [(nzVisible)]="isVisible"
  10. nzTitle="Modal"
  11. nzOkText="Ok"
  12. nzCancelText="Cancel"
  13. (nzOnOk)="handleOk()"
  14. (nzOnCancel)="handleCancel()"
  15. >
  16. <p>Bla bla ...</p>
  17. <p>Bla bla ...</p>
  18. <p>Bla bla ...</p>
  19. </nz-modal>
  20. </div>
  21. <br />
  22. <button nz-button nzType="info" (click)="showConfirm()">Confirm</button>
  23. `
  24. })
  25. export class NzDemoModalLocaleComponent {
  26. isVisible = false;
  27. constructor(private modalService: NzModalService) {}
  28. showModal(): void {

  31. handleOk(): void {
  32. this.isVisible = false;
  33. }
  34. handleCancel(): void {
  35. this.isVisible = false;
  36. }
  37. showConfirm(): void {
  38. this.modalService.confirm({
  39. nzTitle: 'Confirm',
  40. nzContent: 'Bla bla ...',
  41. nzOkText: 'OK',
  42. nzCancelText: 'Cancel'
  43. });
  44. }
  45. }

自定义位置

您可以直接使用 nzStyle.top 或配合其他样式来设置对话框位置。

注意 由于Angular的样式隔离,若在Component中没有加入encapsulation: ViewEncapsulation.None,则您可能需要在自定义样式内采用::ng-deep来覆盖NgZorro的样式

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-modal-position',
  4. template: `
  5. <button nz-button nzType="primary" (click)="showModalTop()">Display a modal dialog at 20px to Top</button>
  6. <nz-modal
  7. [nzStyle]="{ top: '20px' }"
  8. [(nzVisible)]="isVisibleTop"
  9. nzTitle="20px to Top"
  10. (nzOnCancel)="handleCancelTop()"
  11. (nzOnOk)="handleOkTop()"
  12. >
  13. <p>some contents...</p>
  14. <p>some contents...</p>
  15. <p>some contents...</p>
  16. </nz-modal>
  17. <br /><br />
  18. <button nz-button nzType="primary" (click)="showModalMiddle()">Vertically centered modal dialog</button>

  21. [(nzVisible)]="isVisibleMiddle"
  22. nzTitle="Vertically centered modal dialog"
  23. (nzOnCancel)="handleCancelMiddle()"
  24. (nzOnOk)="handleOkMiddle()"
  25. >
  26. <p>some contents...</p>

服务方式创建

Modal的service用法,示例中演示了用户自定义模板、自定义component、以及注入模态框实例的方法。

注意 如果使用Component模式,则需要在NgModule中的 declarationsentryComponents 加入自定义的Component

API

NzModalServiceservice

对话框当前分为2种模式,普通模式确认框模式(即Confirm对话框,通过调用confirm/info/success/error/warning弹出),两种模式对API的支持程度稍有不同。

参数说明类型默认值

nzAfterCloseModal 完全关闭后的回调,可监听close/destroy方法传入的参数EventEmitter-
nzBodyStyleModal body 样式object-
nzCancelText取消按钮文字。设为 null 表示不显示取消按钮(若在普通模式下使用了 nzFooter 参数,则该值无效)string取消
nzClosable是否显示右上角的关闭按钮。确认框模式下该值无效(默认会被隐藏)booleantrue
nzOkLoading确定按钮 loadingbooleanfalse
nzCancelLoading取消按钮 loadingbooleanfalse
nzOkDisabled是否禁用确定按钮booleanfalse
nzCancelDisabled是否禁用取消按钮booleanfalse

注意

<nz-modal> 默认关闭后状态不会自动清空, 如果希望每次打开都是新内容,请采用 NzModalService 服务方式创建对话框(当以服务方式创建时,默认会监听 nzAfterClose 并销毁对话框)。

通过 NzModalService 服务方式创建的对话框需要自行管理其生命周期。比如你在页面路由切换时,服务方式创建的对话框并不会被销毁,你需要使用对话框引用来手动销毁(NzModalRef.close()NzModalRef.destroy())。

采用服务方式创建普通模式对话框

您可调用 NzModalService.create(options) 来动态创建普通模式对话框,这里的 options 是一个对象,支持上方API中给出的支持 普通模式 的参数

确认框模式 - NzModalService.method()

包括:

  • NzModalService.info
  • NzModalService.success
  • NzModalService.error
  • NzModalService.warning
  • NzModalService.confirm以上均为一个函数,参数为 object,与上方API一致。部分属性类型或初始值有所不同,已列在下方:

以上函数调用后,会返回一个引用,可以通过该引用关闭弹窗。

  1. constructor(modal: NzModalService) {
  2. const ref: NzModalRef = modal.info();
  3. ref.close(); // 或 ref.destroy(); 将直接销毁对话框
  4. }

NzModalService的其他方法/属性service

方法/属性说明类型
openModals当前打开的所有Modal引用列表NzModalRef[]
afterAllClose所有Modal完全关闭后的回调Observable<void>
closeAll()关闭所有模态框function

NzModalRef

NzModalRef 对象用于控制对话框以及进行内容间的通信

通过服务方式 NzModalService.xxx() 创建的对话框,都会返回一个 NzModalRef 对象,用于操控该对话框(若使用nzContent为Component时,也可通过依赖注入 NzModalRef 方式获得此对象),该对象具有以下方法:

方法/属性说明
afterOpen同nzAfterOpen,但类型为Observable<void>
afterClose同nzAfterClose,但类型为Observable<result:any>
open()打开(显示)对话框。若对话框已销毁,则调用此函数将失效
close(result: any)关闭(隐藏)对话框。注:当用于以服务方式创建的对话框,此方法将直接 销毁 对话框(同destroy方法)
destroy(result: any)销毁对话框。注:仅用于服务方式创建的对话框(非服务方式创建的对话框,此方法只会隐藏对话框)
getContentComponent()获取对话框内容中nzContent的Component实例instance。注:当对话框还未初始化完毕(ngOnInit未执行)时,此函数将返回undefined
triggerOk()手动触发nzOnOk
triggerCancel()手动触发nzOnCancel

全局配置

全局配置(NZ_MODAL_CONFIG)如果要进行全局默认配置,你可以设置提供商 NZ_MODAL_CONFIG 的值来实现。(如:在你的模块的providers中加入 { provide: NZ_MODAL_CONFIG, useValue: { nzMask: false }}NZ_MODAL_CONFIG 可以从 ng-zorro-antd 中导入)

全局配置,组件默认值,组件层级配置之间的权重如下:

组件层级配置 > 全局配置 > 组件默认值

当前支持的全局配置

  1. {
  2. provide: NZ_MODAL_CONFIG,
  3. useValue: {
  4. nzMask?: boolean; // 是否展示遮罩
  5. nzMaskClosable?: boolean; // 点击蒙层是否允许关闭
  6. }
  7. }

注:全局配置并无默认值,因为nzMask和nzMaskClosable默认值存在于组件中

ModalButtonOptions(用于自定义底部按钮)

可将此类型数组传入 nzFooter,用于自定义底部按钮。

按钮配置项如下(与button组件保持一致):

  1. nzFooter: [{
  2. label: string; // 按钮文本
  3. type?: string; // 类型
  4. shape?: string; // 形状
  5. ghost?: boolean; // 是否ghost
  6. size?: string; // 大小
  7. autoLoading?: boolean; // 默认为true,若为true时,当onClick返回promise时此按钮将自动置为loading状态
  8. // 提示:下方方法的this指向该配置对象自身。当nzContent为组件类时,下方方法传入的contentComponentInstance参数为该组件类的实例
  9. // 是否显示该按钮
  10. show?: boolean | ((this: ModalButtonOptions, contentComponentInstance?: object) => boolean);
  11. // 是否显示为loading
  12. loading?: boolean | ((this: ModalButtonOptions, contentComponentInstance?: object) => boolean);
  13. // 是否禁用
  14. disabled?: boolean | ((this: ModalButtonOptions, contentComponentInstance?: object) => boolean);
  15. // 按钮点击回调
  16. onClick?(this: ModalButtonOptions, contentComponentInstance?: object): void | Promise&lt;void&gt; | any;
  17. }]

以上配置项也可在运行态实时改变,来触发按钮行为改变。
