如果您使用ASP.NET,您可以使用ASP.NET比較驗證[ASP.NET Date Validator。
<asp:TextBox ID="tb" runat="server"></asp:TextBox>
<asp:CompareValidator ID="cv" runat="server"
ControlToValidate="tb" ErrorMessage="* Please enter a valid date!" Text="*"
Operator="DataTypeCheck" Type="Date"></asp:CompareValidator>
****更新**
我拿了這是由比較驗證上面執行的JavaScript和包裹着它的自定義jQuery驗證方法:
<script type="text/javascript">
$(document).ready(function() {
$.validator.addMethod("truedate", function (value, element, params) {
function GetFullYear(year, params) {
var twoDigitCutoffYear = params.cutoffyear % 100;
var cutoffYearCentury = params.cutoffyear - twoDigitCutoffYear;
return ((year > twoDigitCutoffYear) ? (cutoffYearCentury - 100 + year) : (cutoffYearCentury + year));
}
var yearFirstExp = new RegExp("^\\s*((\\d{4})|(\\d{2}))([-/]|\\. ?)(\\d{1,2})\\4(\\d{1,2})\\.?\\s*$");
try {
m = value.match(yearFirstExp);
var day, month, year;
if (m != null && (m[2].length == 4 || params.dateorder == "ymd")) {
day = m[6];
month = m[5];
year = (m[2].length == 4) ? m[2] : GetFullYear(parseInt(m[3], 10));
}
else {
if (params.dateorder == "ymd") {
return null;
}
var yearLastExp = new RegExp("^\\s*(\\d{1,2})([-/]|\\. ?)(\\d{1,2})(?:\\s|\\2)((\\d{4})|(\\d{2}))(?:\\s\u0433\\.)?\\s*$");
m = value.match(yearLastExp);
if (m == null) {
return null;
}
if (params.dateorder == "mdy") {
day = m[3];
month = m[1];
}
else {
day = m[1];
month = m[3];
}
year = (m[5].length == 4) ? m[5] : GetFullYear(parseInt(m[6], 10));
}
month -= 1;
var date = new Date(year, month, day);
if (year < 100) {
date.setFullYear(year);
}
return (typeof (date) == "object" && year == date.getFullYear() && month == date.getMonth() && day == date.getDate()) ? date.valueOf() : null;
}
catch (err) {
return null;
}
}, "Please enter an actual date.");
$("#form1").validate();
$("#one").rules('add',
{
truedate: {
cutoffyear: '2029',
dateorder: 'mdy'
}
});
});
</script>
<input id="one" />
這取決於你的正確日期的定義是什麼? – 2010-04-26 17:53:36
例如30/30/2008是不是有效的日期。 – 2010-04-26 18:00:59
