如何在时刻 js 日历中禁用所选日期和上一个日期..? [英] How to disable the selected and previous date in moment js calendar..?

问题描述

我正在使用 Moment js 将日历集成到一个项目中.

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

我想禁用以前的日期和其他选定的日期.

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

我试过了，但日期没有被禁用.

I tried but date is not disabled.

这是我的 javascript 代码，

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() {

我尝试禁用日期，但它不起作用.你们能帮帮我吗.

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

推荐答案

设置

在这个答案中，我将使用几个演示来剖析您的多个场景.它们中的每一个都有一个共同点，即它们在某些日子里添加了一个 disabled 类.我不会在每个演示中都重复这一点，所以在这里，一次:

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:

内部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);
  }
});

在 CSS 的末尾

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

禁用以前的日期

你可以使用 MomentJS 的 isBefore方法来确定哪些日子已经过去并且应该被禁用，并禁用对它们的点击.

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'];
  if(day.month() !== this.current.month()) {
    classes.push('other');
  } else if (today.isSame(day, 'day')) {
    classes.push('today');
  }
  // Here, add a class to disable past dates
  if (day.isBefore(moment(), 'day')) {
    classes.push('disabled');
  }
  return classes.join(' ');
}

/* ... */

JSFiddle 演示 (我不得不从 SO 中删除它, 字符太多)

在这里，我们将定义一个包含日期的数组，并使用该数组来决定是否禁用日期.Array 中的日期可以是任何格式，但在该 Array 中查找日期时需要匹配该格式.

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.

在我的示例中，我使用 YYYY-MM-DD 格式(您可以找到其他格式 这里)

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(' ');
}

/* ... */
