日期选择器范围不工作

您的代码中有几个错误:

• 日期选择器没有onSelect选项，相反，您必须侦听changeDate事件
• 日期选择器既没有minDate也没有maxDate选项/方法，你必须使用setStartDate和setEndDate

下面是一个工作示例:

function set_parameters() {
  var date_start_input = $('#start_date');
  var date_end_input = $('#end_date');
  var container = $('.bootstrap-iso form').length>0 ? $('.bootstrap-iso form').parent() : "body";
   
  var options = {
    format: 'MM dd, yyyy',
    container: container,
    todayHighlight: true,
    autoclose: true,
    orientation: 'top left'
  };
  date_start_input.datepicker(options).on('changeDate', function(e){
    date_end_input.datepicker("setStartDate", e.date);
  });
  date_end_input.datepicker(options).on('changeDate', function(e){
    date_start_input.datepicker("setEndDate", e.date);
  });
};
$(document).ready(function() {
   set_parameters();
});

<input class="form-control" id="end_date" name="end_date" placeholder="MM DD, YYYY" type="text" style="border-radius: 0;"/>

我认为你需要的代码是:

<div class="container">
<div class='col-md-5'>
    <div class="form-group">
        <div class='input-group date' id='datetimepicker6'>
            <input type='text' class="form-control" />
            <span class="input-group-addon">
                <span class="glyphicon glyphicon-calendar"></span>
            </span>
        </div>
    </div>
</div>
<div class='col-md-5'>
    <div class="form-group">
        <div class='input-group date' id='datetimepicker7'>
            <input type='text' class="form-control" />
            <span class="input-group-addon">
                <span class="glyphicon glyphicon-calendar"></span>
            </span>
        </div>
    </div>
</div>
</div>
<script type="text/javascript">
$(function () {
    $('#datetimepicker6').datetimepicker();
    $('#datetimepicker7').datetimepicker({
        useCurrent: false //Important! See issue #1075
    });
    $("#datetimepicker6").on("dp.change", function (e) {
        $('#datetimepicker7').data("DateTimePicker").minDate(e.date);
    });
    $("#datetimepicker7").on("dp.change", function (e) {
        $('#datetimepicker6').data("DateTimePicker").maxDate(e.date);
    });
});
</script>

这不是我的代码。我在这里找到的:https://eonasdan.github.io/bootstrap-datetimepicker/#linked-pickers.

看起来好像你只是在文档准备函数中缺少了一个右括号

$(document).ready(function() {
  set_parameters();
}

function set_parameters() {
   var date_start_input=$('#start_date');
   var date_end_input=$('#end_date');
   var container=$('.bootstrap-iso form').length>0 ? $('.bootstrap-iso form').parent() : "body";
   var options_start={
      format: 'MM dd, yyyy',
      container: container,
      todayHighlight: true,
      autoclose: true,
      orientation: 'top left',
      onSelect: function(selectedDate) {
         date_end_input.datepicker("option", "maxDate", selectedDate);
      }  
   };
   var options_end={
      format: 'MM dd, yyyy',
      container: container,
      todayHighlight: true,
      autoclose: true,
      orientation: 'top left',
      onSelect: function(selectedDate) {
        date_start_input.datepicker("option", "minDate", selectedDate);  
      }  
   };
   date_start_input.datepicker(options_start);
   date_end_input.datepicker(options_end);
};
$(document).ready(function() {
   set_parameters();
})
