在JQuery UI datepicker中禁用当前日期之前的日期

Question

我想在日期选择器中禁用当前日期之前的日期.这该怎么做？

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

$(function() {
  var $dp2 = $("#datepicker2");
  $(document).ready(function() {
    $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;
}

在JQuery UI datepicker 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;
}

另请注意,您需要在脚本中仅使用一个文档就绪事件.
