javascript - Angular 2中的日期选择器问题

Question

我编写了一个简单的日期选择器程序。并且运作良好。但我现在面临的问题是，如果我需要两个日期选择器，我需要编写两个 jQuery onChange 事件。我需要的是两个使用相同 jQuery onChange 事件的输入日期选择器。在经典的 jQuery 中我可以使用类，但我不知道如何在 typescript 中实现它。任何意见将是有益的。谢谢。

app.component.ts:

  @ViewChild('dateselect') ds: ElementRef;
  ngAfterViewInit() {
    jQuery(this.ds.nativeElement)
      .on('change', () => {
        jQuery(this.ds.nativeElement).attr("data-date", moment(jQuery(this.ds.nativeElement).val(), "YYYY-MM-DD").format('DD MMM YYYY'));

      });
  }

app.component.html

<input type="date" #dateselect name="from" data-date-format="DD/MMM/YYYY">
<!--<input type="date" #dateselect name="to" data-date-format="DD/MMM/YYYY">-->

您一定正在尝试使用日期范围选择器。 我使用了相同的引导日期范围选择器，你可以找到这个 DateRangePicker链接

You needs to add and import daterangepicker.js and daterangepicker.css in your angular 2 ProjectConfig.ts

找到以下代码供您引用。 希望它能更好地帮助您。

tools/config/project.config.ts

import { join } from 'path';
import { SeedConfig } from './seed.config';

export class ProjectConfig extends SeedConfig {
  PROJECT_TASKS_DIR = join(process.cwd(), this.TOOLS_DIR, 'tasks', 'project');

  constructor() {
    super();
    this.NPM_DEPENDENCIES = [
        ...this.NPM_DEPENDENCIES,            
        { src: '../../src/client/js/jquery-1.11.1.min.js', inject: 'libs'},
        { src: '../../src/client/js/moment.min.js', inject: 'libs'},
        { src: '../../src/client/js/daterangepicker.js', inject: 'libs' },
        { src: '../../src/client/css/daterangepicker.css', inject: true },
    ];

    // Add `local` third-party libraries to be injected/bundled.
    }
}
