Question

我使用jQuery validate plugin和maskedInput插件为输入做了自定义日期和时间验证。

有没有办法在自定义验证中进行验证，以防止输入比当年更大的一年？

我的代码：

$("#date").mask("99/99/9999 99:99", {
  placeholder: "mm/dd/yyyy hh:mm"
});
$.validator.addMethod("dateTime", function(value, element) {
  var stamp = value.split(" ");
  var validDate = !/Invalid|NaN/.test(new Date(stamp[0]).toString());
  var validTime = /^(([0-1]?[0-9])|([2][0-3])):([0-5]?[0-9])(:([0-5]?[0-9]))?$/i.test(stamp[1]);
  return this.optional(element) || (validDate && validTime);
}, "Invalid datetime.");

$('#form').validate({
  rules: {
    date: {
      required: true,
      dateTime: true
    }
  },
  messages: {
    date: {
      required: ""
    }
  }
})

<form action='' method='post' id='form'>
  <input type='text' name='date' value='' id='date' placeholder='mm/dd/yyyy hh:mm'>
</form>

Answer 1

您可以使用addMethod创建自己的方法，如下所示：

jQuery.validator.addMethod("minDate", function (value, element) {
    var now = new Date().getFullYear();
    var myDate = new Date(value).getFullYear();
    return this.optional(element) || myDate < now;
});

$('#form').validate({
    rules: {
      date: {
        required: true,
        dateTime: true,
        minDate: true
      }
    },
    messages: {
      date: {
        minDate: "The date(year) must not be in the future"
      }
    }
})

希望这有帮助！

添加检查年份的新方法

cellForRowAtIndexPath

在验证规则中添加相同内容

jQuery.validator.addMethod("minYear", function (value, element) {
    var year = new Date(value).getFullYear();
    var curentYear = new Date().getFullYear();
    return this.optional(element) || year <= curentYear;
}, 'Year can not be greater than current year');

如何防止未来年度的dateTime验证？
