模态框是项目中经常会用到的一个公共功能,通常会被用左提示框或者扩展选项框。
下面,我用一个小例子来简单展示实现模态框功能的过程:
1、为项目加包:
ng add ngx-bootstrap
2、在xxx.module.ts(模块.ts文件)中引入:
... import { ModalModule } from "ngx-bootstrap/modal"; ... @NgModule({ imports: [ ... ModalModule.forRoot(), ... ] }) ...
3、创建一个模块框公共组件:
//.ts部分 import { Component } from '@angular/core'; import { BsModalRef } from 'ngx-bootstrap'; @Component({ selector: 'response-modal', templateUrl: './response-modal.html' }) export class ResponseModalService { public header: string; public body: string; constructor(public modalRef: BsModalRef ) {} }
<!-- 模态框模板部分 .html --> <style> .centerize { text-align: center; } </style> <div class="container-fluid"><!-- 模态框容器样式 --> <div class="modal-header"><!-- 框头样式 --> <h5>{{ header }}</h5> <button type="button" class="close pull-right" aria-label="Close" (click)="modalRef.hide()"> <!-- 关闭按钮样式 --> <span aria-hidden="true">×</span> </button> </div> <div class="modal-body" style="white-space: pre-line;"><!-- 框内容样式 --> {{ body }} </div> <div class="centerize"> <button type="button" text-aling="center" class="btn btn-primary mr-2" (click)="modalRef.hide()">OK</button><!-- 常规按钮样式 --> </div> <p> </div>
4、在xxx.page.ts(模版.ts文件)中引入并,并调用:
import { BsModalRef, BsModalService } from "ngx-bootstrap";//引入模态框资源对象及服务对象
import { ResponseModalService } from "src/app/shared/component/response-modal";//引入上面创建好的模态框组件
... public modalRef: BsModalRef; ... constructor( private modalService: BsModalService, ... ) { ... } ... public openUpdateNotification(message: string): void { this.modalRef = this.modalService.show(ResponseModalService, {//初始化一个之前创建好的模态框组件 initialState: { header: "", body: message }, class: "modal-lg" }); }
5、在合适位置调用打开模态框的方法openUpdateNotification即可。
