Question

我之前曾问过要为另一个日期选择器的月/年更改设置一个日期选择器日期。我没有确切的答案，但是通过引用各种堆栈溢出答案，我设法以某种方式设法将最小和最大日期设置为日期选择器。但是最小和最大日期设置无法正常工作。

月份和年份选择日期选择器：

 <label> Month</label>
 <div class="input-group date">
    <input type="text" class="form-control pull-right" id="txtMonth" onchange="MonthDatePick();">
    <div class="input-group-addon">
        <i class="fa fa-calendar"></i>
    </div>
</div>

我选择的月份日期选择日期选择器：

<div class="col-lg-3">
    <label> From</label>
    <div class="input-group date">
        <input type="text" class="form-control pull-right" id="txtFrom">
        <div class="input-group-addon">
            <i class="fa fa-calendar"></i>
        </div>
    </div>
</div>

脚本：

function MonthDatePick() {
  var month = $('#txtMonth').datepicker('getDate').getMonth() + 1;//('getMonth');            
var year = $('#txtMonth').datepicker('getDate').getFullYear();//('getFullYear');   
var minDate = new Date(year, month-1, 1);
 var maxDate = new Date(year,month, 0);
$("#txtFrom").datepicker({
    autoclose: true,
    minDate: minDate,
    maxDate: maxDate,
    format: 'dd/mm/yyyy',
    //defaultDate:minDate,
    changeMonth: false,
    changeYear: false,
});
}

我调试后发现，选择月份时，已定义了最小和最大日期。对于Ex：如果选择，Feb 2018表示

min date comes as :01/02/2018

max date comes as : 28/02/2018,

但更改不会复制到我选择日期的日期选择器中

该如何解决？

Answer 1

您使用的选项不正确：

  function MonthDatePick() {
      var month = $('#txtMonth').datepicker('getDate').getMonth() + 1;//('getMonth');            
      var year = $('#txtMonth').datepicker('getDate').getFullYear();//('getFullYear');   
      var minDate = new Date(year, month-1, 1);
      var maxDate = new Date(year,month, 0);
      $("#txtFrom").datepicker({
        autoclose: true,
        startDate: minDate,
        endDate: maxDate,
        format: 'dd/mm/yyyy',
        //defaultDate:minDate,
        changeMonth: false,
        changeYear: false,
      });
    }

将minDate更改为startDate，将maxDate更改为endDate

请参见bootstrap-datepicker documentation

Answer 2

您当前正在尝试重新创建现有的日期选择器。而是使用setStartDate和setEndDate方法修改当前实例。

$("#txtClaimFrom").datepicker("setStartDate", minDate);
$("#txtClaimFrom").datepicker("setEndDate", maxDate);

$(document).ready(function() {
  $('#txtClaimMonth').datepicker({
    autoclose: true,
    format: "MM yyyy",
    viewMode: "months",
    minViewMode: "months",
  });
  $('#txtClaimFrom').datepicker({
    autoclose: true,
    format: 'dd/mm/yyyy'
  })
});

function MonthDatePick() {
  var month = $('#txtClaimMonth').datepicker('getDate').getMonth() + 1; //('getMonth');            
  var year = $('#txtClaimMonth').datepicker('getDate').getFullYear(); //('getFullYear');   
  var minDate = new Date(year, month - 1, 1);
  var maxDate = new Date(year, month, 0);
  $("#txtClaimFrom").datepicker("setStartDate", minDate);
  $("#txtClaimFrom").datepicker("setEndDate", maxDate);
}

.col-lg-3 { margin-bottom: 180px; }

<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.4.0/js/bootstrap-datepicker.min.js"></script>
<div class="col-lg-3">
  <label>Claim Month</label>
  <div class="input-group date">
    <input type="text" class="form-control pull-right" id="txtClaimMonth" onchange="MonthDatePick();">
    <div class="input-group-addon bg-purple">
      <i class="fa fa-calendar"></i>
    </div>
  </div>
</div>
<div class="col-lg-3">
  <label>Claim From</label>
  <div class="input-group date">
    <input type="text" class="form-control pull-right" id="txtClaimFrom">
    <div class="input-group-addon bg-purple">
      <i class="fa fa-calendar"></i>
    </div>
  </div>
</div>

或者，您可以remove当前的日期选择器，然后从头开始对其进行初始化。请注意，Bootstrap Datepicker使用startDate和endDate作为选项，而不使用minDate和maxDate。

$("#txtClaimFrom").datepicker("remove");
$("#txtClaimFrom").datepicker({
  autoclose: true,
  startDate: minDate,
  endDate: maxDate,
  format: 'dd/mm/yyyy',
  changeMonth: false,
  changeYear: false,
});

$(document).ready(function() {
  $('#txtClaimMonth').datepicker({
    autoclose: true,
    format: "MM yyyy",
    viewMode: "months",
    minViewMode: "months",
  });
  $('#txtClaimFrom').datepicker({
    autoclose: true,
    format: 'dd/mm/yyyy'
  })
});

function MonthDatePick() {
  var month = $('#txtClaimMonth').datepicker('getDate').getMonth() + 1; //('getMonth');            
  var year = $('#txtClaimMonth').datepicker('getDate').getFullYear(); //('getFullYear');   
  var minDate = new Date(year, month - 1, 1);
  var maxDate = new Date(year, month, 0);
  $("#txtClaimFrom").datepicker("remove");
  $("#txtClaimFrom").datepicker({
    autoclose: true,
    startDate: minDate,
    endDate: maxDate,
    format: 'dd/mm/yyyy',
    changeMonth: false,
    changeYear: false,
  });
}

.col-lg-3 {
  margin-bottom: 180px;
}

Answer 3

请尝试使用此代码

HTML代码：

<label> Month</label>
<div class="input-group date">
<input type="text" class="form-control pull-right" id="txtMonth" onchange="MonthDatePick();">
<div class="input-group-addon">
    <i class="fa fa-calendar"></i>
</div>
</div>

<div class="col-lg-3">
<label> From</label>
<div class="input-group date">
    <input type="text" class="form-control pull-right" id="txtFrom">
    <div class="input-group-addon">
        <i class="fa fa-calendar"></i>
    </div>
</div>
</div>

JS代码：

<script type="text/javascript">
   $("#txtMonth").datepicker({
   autoclose: true,
   startView: "months", 
   minViewMode: "months",
   format: 'M-yyyy',
   //defaultDate:minDate,
   changeMonth: false,
   changeYear: false,
});

function MonthDatePick() {
   var month = $('#txtMonth').datepicker('getDate').getMonth() + 1;//('getMonth');            
   var year = 
   $('#txtMonth').datepicker('getDate').getFullYear();//('getFullYear');   
   var minDate = new Date(year, month-1, 1);
   minDate = minDate.toLocaleDateString('en-GB');
   var maxDate = new Date(year,month, 0);
   maxDate = maxDate.toLocaleDateString('en-GB');
   $("#txtFrom").datepicker('destroy').datepicker({
      autoclose: true,
      startDate: minDate,
      endDate: maxDate,
      format: 'dd/mm/yyyy',
      //defaultDate:minDate,
      changeMonth: false,
      changeYear: false,
   });
  $('#txtFrom').datepicker('setDate',minDate);
}
</script>

代码输出：

为什么我的最小和最大日期设置在日期选择器中不起作用？
