我有一个使用javascript和moment.js的日历功能，它工作得很好。虽然我想添加链接，类似于html，添加到包含eventName的字符串中，这样日历中显示的eventName就是可点击的链接。我已经包含了函数和字符串，包括每个eventName。有什么建议吗？

!function() {

var today = moment();
  
function Calendar(selector, events) {
  this.el = document.querySelector(selector);
  this.events = events;
  this.current = moment().date(1);
  this.events.forEach(function(ev) {
   ev.date = moment(ev.date);
  });
  this.draw();
  var current = document.querySelector('.today');
}
  
Calendar.prototype.draw = function() {
  //Create Header
  this.drawHeader();
  
  //Draw Month
  this.drawMonth();
  
  this.drawLegend();
}
  
Calendar.prototype.drawHeader = function() {
  var self = this;
  if(!this.header) {
    //Create the header elements
    this.header = createElement('div', 'header');
    this.header.className = 'header';
  
    this.title = createElement('h1');
  
    var right = createElement('div', 'right');
    right.addEventListener('click', function() { self.nextMonth(); });
  
    var left = createElement('div', 'left');
    left.addEventListener('click', function() { self.prevMonth(); });
  
    //Append the Elements
    this.header.appendChild(this.title); 
    this.header.appendChild(right);
    this.header.appendChild(left);
    this.el.appendChild(this.header);
  }
  
  this.title.innerHTML = this.current.format('MMMM YYYY');
}
  
Calendar.prototype.drawMonth = function() {
  var self = this;
  
  
  if(this.month) {
    this.oldMonth = this.month;
    this.oldMonth.className = 'month out ' + (self.next ? 'next' : 'prev');
    this.oldMonth.addEventListener('webkitAnimationEnd', function() {
      self.oldMonth.parentNode.removeChild(self.oldMonth);
      self.month = createElement('div', 'month');
      self.backFill();
      self.currentMonth();
      self.fowardFill();
      self.el.appendChild(self.month);
      window.setTimeout(function() {
        self.month.className = 'month in ' + (self.next ? 'next' : 'prev');
      }, 16);
    });
  } else {
      this.month = createElement('div', 'month');
      this.el.appendChild(this.month);
      this.backFill();
      this.currentMonth();
      this.fowardFill();
      this.month.className = 'month new';
  }
}
  
Calendar.prototype.backFill = function() {
  var clone = this.current.clone();
  var dayOfWeek = clone.day();
  
  if(!dayOfWeek) { return; }
  
  clone.subtract('days', dayOfWeek+1);
  
  for(var i = dayOfWeek; i > 0 ; i--) {
    this.drawDay(clone.add('days', 1));
  }
}
  
Calendar.prototype.fowardFill = function() {
  var clone = this.current.clone().add('months', 1).subtract('days', 1);
  var dayOfWeek = clone.day();

在日历点击上实现重定向是你必须选择如何做的事情，没有最好的方法，特别是因为我们不知道你的日历构造函数是如何工作的。我只回答你的问题：

是否向javascript字符串添加链接？

如果您事先不知道链接将指向何处，那么您别无选择，只能自己添加一个字段。

如果您确实有一些确定href的方法，请在声明数组之后执行此操作：

const linkMaker = (string) => {
  const href="/path/to/determine/somehow";
  return `<a href={href}>{string}</a>`;
}

dataWithLinks = data.map(dataObject => ({...dataObject, eventName: linkMaker(dataObject.eventName)}));
