为什么我的最小和最大日期设置在我的日期选择器中不起作用？

Question

我之前问过关于 month/year 更改另一个日期选择器的日期设置一个日期选择器的问题。我没有得到确切的答案，但不知何故，我设法通过引用各种堆栈溢出答案来设置最小和最大日期以设置为日期选择器。但是最小和最大日期设置无法正常工作。

年月选择器：

 <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>

我的 select 月份日期选择器：

<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,
});
}

我调试发现当我select月时，定义了最小和最大日期。例如：如果我选择，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的日期 selecting 日期选择器

如何解决这个问题？

Answer 1

您没有使用正确的选项：

  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

见bootstrap-datepicker documentation

Answer 2

您目前正在尝试重新创建现有的日期选择器。相反，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; }

<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 当前日期选择器并从头开始重新初始化它。请注意，Bootstrap Datepicker 使用 startDate 和 endDate 作为选项，而不是 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

请试试这个代码

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>
