在JQuery UI日期选择器中禁用当前日期之前的日期

在JQuery UI日期选择器API中使用minDate属性。

$(function() {
  var $dp1 = $("#datepicker1");
  $dp1.datepicker({
    changeYear: true,
    changeMonth: true,
      minDate:0,
    dateFormat: "yy-m-dd",
    yearRange: "-100:+20",
  });
  var $dp2 = $("#datepicker2");
  $dp2.datepicker({
    changeYear: true,
    changeMonth: true,
    yearRange: "-100:+20",
    dateFormat: "yy-m-dd",
  });
});

$(function() {
  var $dp1 = $("#datepicker1");
  $dp1.datepicker({
    changeYear: true,
    changeMonth: true,
    minDate: 0,
    dateFormat: "yy-m-dd",
    yearRange: "-100:+20",
  });
  var $dp2 = $("#datepicker2");
  $dp2.datepicker({
    changeYear: true,
    changeMonth: true,
    yearRange: "-100:+20",
    dateFormat: "yy-m-dd",
  });
});

p.pfield-wrapper input {
  float: right;
}
p.pfield-wrapper::after {
  content: "'00a0'00a0 "; /* keeps spacing consistent */
  float: right;
}
p.required-field::after {
  content: "*";
  float: right;
  margin-left: -3%;
  color: red;
}

等效Js报价

还要注意，您只需要在脚本中使用一个文档就绪事件。

您可以使用minDate选项

    $dp1.datepicker({
        changeYear: true,
        changeMonth: true,
        dateFormat: "yy-m-dd",
        yearRange: "-100:+20",
        minDate: '0'
    });

演示：Fiddle

javascript
$(document).ready(function() {
    $('#Date').datepicker({
        onSelect: function(dateText, inst) {
            var today = new Date();
            today = Date.parse(today.getMonth()+1+'/'+today.getDate()+'/'+today.getFullYear());
            var selDate = Date.parse(dateText);
            if(selDate < today) {
                $('#Date').val('');
                $(inst).datepicker('show');
            }
        }
    });
});

html

<input type="text" id="Date" value="" />

演示

注意：或使用minDate:0

根据您的示例：

方法1

html

 <p class="pfield-wrapper required-field"> <label>Start Date</label>         <input id="datepicker1" type="text" name="s"  style="width:155px;" required value=""></p>
    <p class="p">End Date<input id="datepicker2" type="text" name="e"  style="width:155px;" value=""></p>

JS

      $(function () {
   var $dp1 = $("#datepicker1");
  $(document).ready(function () {
  $dp1.datepicker({
    changeYear: true,
    changeMonth: true,
        minDate: '0',
    dateFormat: "yy-m-dd",
    yearRange: "-100:+20",
  });
 });
        });
          $(function () {
   var $dp2 = $("#datepicker2");

  $dp2.datepicker({
    changeYear: true,
    changeMonth: true,
       minDate: '0',
    yearRange: "-100:+20",
    dateFormat: "yy-m-dd",
 });
        });

方法2

html

 <p class="pfield-wrapper required-field"> <label>Start Date</label>         <input id="datepicker1" type="text" name="s"  style="width:155px;" required value=""></p>
    <p class="p">End Date<input id="datepicker2" type="text" name="e"  style="width:155px;" value=""></p>

js

 $('#datepicker1').datepicker({
        onSelect: function(dateText, inst) {
            //Get today's date at midnight
            var today = new Date();
            today = Date.parse(today.getMonth()+1+'/'+today.getDate()+'/'+today.getFullYear());
            //Get the selected date (also at midnight)
            var selDate = Date.parse(dateText);
            if(selDate < today) {
                //If the selected date was before today, continue to show the datepicker
                $('#datepicker1').val('');
                $(inst).datepicker('show');
            }
        }
    });

$('#datepicker2').datepicker({
        onSelect: function(dateText, inst) {
            //Get today's date at midnight
            var today = new Date();
            today = Date.parse(today.getMonth()+1+'/'+today.getDate()+'/'+today.getFullYear());
            //Get the selected date (also at midnight)
            var selDate = Date.parse(dateText);
            if(selDate < today) {

                $('#datepicker2').val('');
                $(inst).datepicker('show');
            }
        }
    });

DEMO

如果您有开始日期和结束日期，请尝试此操作

$(document).ready(function(){
$("#txtFromDate").datepicker({
     minDate: '0',
    onSelect: function(selected) {
      $("#txtToDate").datepicker("option","minDate", selected)
    }
});
$("#txtToDate").datepicker({
     minDate: '0',
    onSelect: function(selected) {
       $("#txtFromDate").datepicker("option","maxDate", selected)
    }
});  
});
