语义UI表单验证RegEx与mm / dd / yyyy日期不匹配

我正在尝试验证文本框的文本输入,以仅允许mm / dd / yyyy输入。基于正则表达式测试器,正则表达式似乎对我想要匹配的内容有效。

导致它失败的原因是什么,我该怎么办呢?

RegEx:(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)\d\d

$('.ui.form').form({

        prompt: "Please select a valid mm/dd/yyyy date"
      }]
    },
    timeInput: {
      identifier: 'timeInput',
      rules: [{
        type: "regExp[/^(OFF)|([0-1]?[0-9]|2[0-3]):[0-5][0-9](:[0-5][0-9])? [APap][mM]$/]",
        prompt: "Please select a valid hh:mm AM/PM time"
      }]
    }
  }

因为你的正则表达式是javascript字符串的一部分,所以任何反斜杠都需要使用双反斜杠进行转义。因此\d变为\\d

此外,使用字符串^的开头和字符串$标记的结尾来防止较大字符串(例如01/15/20155)的匹配成功。

<强>结果:

type: "regExp[/^(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)\\d\\d$/]",

<强>段:

$('.ui.form').form({
  inline: true,
  fields: {
    dateInput: {
      identifier: 'dateInput',
      rules: [{
        type: "regExp[/^(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)\\d\\d$/]",
        prompt: "Please select a valid mm/dd/yyyy date"
      }]
    },
    timeInput: {
      identifier: 'timeInput',
      rules: [{
        type: "regExp[/^(OFF)|([0-1]?[0-9]|2[0-3]):[0-5][0-9](:[0-5][0-9])? [APap][mM]$/]",
        prompt: "Please select a valid hh:mm AM/PM time"
      }]
    }
  }
});
