如何在javascript / jquery中的日期选择器中禁用日历中的过去日期？

Question

I am working on a website in which I want the disable the past dates in calendar.

The HTML and JQuery codes which I have used in order to make the calendar are:

 $("#startdate_datepicker").datepicker({numberOfMonths:[1, 2]}); $("#enddate_datepicker").datepicker({numberOfMonths:[1, 2]}); 

 <link href="https://cdn.bootcss.com/jqueryui/1.12.1/jquery-ui.css" rel="stylesheet"/> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script> <div class="dates"> <div class="start_date" style="width:50%;margin-right:3%;"> <input readonly="readonly" class="form-control start_date mb-4" type="text" placeholder="start date" id="startdate_datepicker"> </div> <div class="end_date" style="width:50%;margin-left:3%;"> <input readonly="readonly" class="form-control end_date mb-4" type="text" placeholder="end date" id="enddate_datepicker"> </div> </div> 

Problem Statement:

I am wondering what changes I should make in the code above so that after selecting the start date, the dates before the start date should get disabled on selecting the end date .

You can use the option=beforeShowDay of JQuery UI , then customize the styles for each day like below demo:

As JQuery UI Guide for beforeShowDay :

A function that takes a date as a parameter and must return an array with:

 [0]: true/false indicating whether or not this date is selectable [1]: a CSS class name to add to the date's cell or "" for the default presentation [2]: an optional popup tooltip for this date 

 let startDateUI = $("#startdate_datepicker").datepicker({ numberOfMonths:[1, 2], todayHighlight: true, beforeShowDay: function (calDate) { return calDate - new Date() < 0 ? [false, '', ''] : [true, '',''] } }); $("#enddate_datepicker").datepicker({ numberOfMonths:[1, 2], todayHighlight: true, beforeShowDay: function (calDate) { let selectedStartDate = $( "#startdate_datepicker" ).datepicker( "getDate" ) return calDate - selectedStartDate < 0 ? [false, 'disable-day', 'not available day!!!'] : [true, '',''] } }); 

 .disable-day{ background-color:red; }

Use .datepicker("option", "minDate", <value of start date>) to set the earliest selectable date. "maxDate" will allow you to set the latest selectable date.
