Question

该图像显示了视图和html代码，即html代码中的“工具提示”类，但是当我将其悬停时，它什么也没有显示。应该显示为“ haha1”，但我不知道如何解决。

import { Component, OnInit, ViewChild } from '@angular/core';
import { OptionsInput } from '@fullcalendar/core';
import timeslot from '@fullcalendar/resource-timeline';
import interactionPlugin from '@fullcalendar/interaction';

import Tooltip from 'tooltip.js';
declare let $: any;

export class AppComponent implements OnInit{
  options: OptionsInput;

  id: any;
  @ViewChild('fullcalendar') fullcalendar: CalendarComponent;
  ngOnInit(): void {
    this.options = {
      editable: false,
      resourceLabelText: 'Rooms',
      // eventRender: (info) => {
      //   info.el.setAttribute('data-toggle', "tooltip");
      //   info.el.setAttribute('title', info.event.extendedProps.description)
      //   info.el.setAttribute('data-placement', 'top')
      //
      //   $(() => {
      //     $('[data-toggle=\'tooltip\']').tooltip({
      //       position: 'bottom right'

Answer 1

在使用工具提示时检查角材及其位置，方法是从角材@ angular.io

Answer 2

使用Popper.js和Tooltip.js并不是更好的方法。

您可以使用Angular Official文档中的Tooltip API

对于带有Angular 7的Fullcalendar
