How to disable the selected and previous date in m

问题:

I'm integrating calender in one of project using moment js.

I want to disable previous date and some other selected date.

I tried but date is not disabled.

Here is my javascript code,

!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) {
      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();

    }
  }

<div id="calendar"></div>
<script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.5.1/moment.min.js"></script>

I tried to disabling date but, it doesn't work. Can you guys please help me.

回答1:

Setup

In this answer, I'll disect multiple scenarios of yours, using several demos. Each of these have in common the fact that they're adding a disabled class on some days. I won't repeat this in every demo, so here it is, once:

Inside Calendar.prototype.drawDay

//Outer Day
var outer = createElement('div', this.getDayClass(day));
outer.addEventListener('click', function() {
  // Only open if the element is not disabled
  if (!this.classList.contains('disabled')) {
    self.openDay(this);
  }
});

At the end of your CSS

.day.disabled {
  color: #888;
  cursor: default;
}

Disabling previous dates

You can use MomentJS's isBefore method to determine which days are past and should be disabled, and disable clicks on them.

/* ... */

Calendar.prototype.getDayClass = function(day) {
  classes = ['day'];

Disabling all dates, except for some defined in an Array

Here, we're going to define an Array containing dates, and use that Array to decide whether or not to disable dates. The dates in your Array can be of any format, but you need to match that format when looking for a date in that Array.

In my example, I use the YYYY-MM-DD format (you can find other formats here)

/* Have this, somewhere in your code */

var allowedDates = [
  '2018-04-14',
  '2018-05-01',
  '2018-05-02'
  /* ... */
];

/* ... */

Calendar.prototype.getDayClass = function(day) {
  classes = ['day'];
  if(day.month() !== this.current.month()) {
    classes.push('other');
  } else if (today.isSame(day, 'day')) {
    classes.push('today');
  }
  // Here, add a class to disable disallowed dates
  if (allowedDates.indexOf(day.format('YYYY-MM-DD')) < 0) {
    classes.push('disabled');
  }
  return classes.join(' ');
}
