在moment.js日历中将事件添加到特定日期？

Posted 2021-04-20

我有一个使用moment.js和一些CSS创建的事件日历。

它目前在一些日期随机添加一些事件，工作正常。

但我需要知道如何将事件添加到特定日期。

例如：{eventName: 'Free Tamale Night', calendar: 'Other', color: 'green', date: '10/10/2018'}

这是我到目前为止：

https://jsfiddle.net/hz3e4wj6/2/

这是我的javascript代码：

!function() {

  var today = moment();

  function Calendar(selector, events) {
    this.el = document.querySelector(selector);
    this.events = events;
    this.current = moment().date(1);
    this.draw();
    var current = document.querySelector('.today');
    if(current) {
      var self = this;
      window.setTimeout(function() {
        self.openDay(current);
      }, 500);
    }
  }

  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;

    this.events.forEach(function(ev) {
     ev.date = self.current.clone().date(Math.random() * (29 - 1) + 1);
    });


    if(this.month) {

  function addDate(ev) {

  }

  var calendar = new Calendar('#calendar', data);

}();

任何帮助，将不胜感激。

提前致谢。

答案

有一个代码可以为data变量中的事件分配随机日期。 您需要使用代码来替换它，而不是根据每个事件条目中的moment属性来设置date日期。

所以，你需要替换这个：

this.events.forEach(function(ev) {
  ev.date = self.current.clone().date(Math.random() * (29 - 1) + 1);
});

有了这个：

this.events.forEach(function(ev) {
  ev.date = moment(ev.date, 'DD/MM/YYYY')
});

这是一个JS fiddle solution与上面的变化。
