动态调整bootstrap datepicker的日期范围

Question

我需要帮助根据下拉列表中选择的数据值动态调整日期选择器的日期范围。我尝试使用下面编写的代码，但它只是没有用。

我使用bootstrap，jquery和bootstrap datepicker。

这是我的代码

<link rel="stylesheet" href="<?php echo base_url(); ?>plug/bootstrap.min.css"/>
<link rel="stylesheet" href="<?php echo base_url(); ?>plug/bootstrap-datepicker3.min.css"/>
<script src="<?php echo base_url(); ?>plug/jquery-3.1.1.min.js"></script>
<script src="<?php echo base_url(); ?>plug/bootstrap.min.js"></script>
<script src="<?php echo base_url(); ?>plug/bootstrap-datepicker.min.js"></script>

<?php
$data[0] = array("id"=>"2", "name" => "Anton", "date_start" => "2016-10-04", "date_end" => "2016-10-14");
$data[1] = array("id"=>"4", "name" => "Boby", "date_start" => "2016-10-09", "date_end" => "2016-10-29");
$data[2] = array("id"=>"5", "name" => "Ciara", "date_start" => "2016-10-01", "date_end" => "2016-10-31");
$data[3] = array("id"=>"6", "name" => "Don", "date_start" => "2016-10-05", "date_end" => "2016-12-31");
$data[4] = array("id"=>"7", "name" => "Ester", "date_start" => "2016-10-01", "date_end" => "2016-12-31");
?>

Answer 1

请你修改你的HTML一点，以形成<option>，如：

<option value='2' data-date_start="2016-10-04" data-date_end="2016-10-14">Anton</option>

此处date_start和date_end位于两个不同的属性中，因此很容易抓住它：

$(document).ready(function() {
  var start = null;
  var end = null;
  $('#date').change(function() {

    start = $(this).find(":selected").data("date_start");
    end = $(this).find(":selected").data("date_end");
    $('.input-group.date').datepicker("remove"); //clearing the previos options and again initiating datepicker
    initDatePicker();
  });

  function initDatePicker() {
    $('.input-group.date').datepicker({
      format: "yyyy-mm-dd",
      startDate: new Date(start),
      endDate: new Date(end),
      autoclose: false
    });
  }

});
