下面的实现方式,jQuery UI 的 Datepicker 插件能够支持,但不能被 java.sql.Date.valueOf() 方法接受,会抛出异常 java.lang.IllegalArgumentException。
?
var today = new Date(); var m = today.getMonth() + 1; var d = today.getDate(); var str = today.getFullYear() + "-" + m + "-" + d; $("#source_time").val(str);
?
?
因为 java.sql.Date.valueOf() 只接受 yyyy-mm-dd 格式字符串。
?
public static Date valueOf(String?s)
Date
?value.
?
s
?- a?String
?object representing a date in in the format "yyyy-mm-dd"java.sql.Date
?object representing the given dateIllegalArgumentException
?- if the date given is not in the JDBC date escape format (yyyy-mm-dd)所以必须要对月份和日期调整格式,如果只有一位数字,在前面加0。如下所示:
?
var today = new Date(); var m = today.getMonth() + 1; var mm = m < 10 ? "0" + m : m; var d = today.getDate(); var dd = d < 10 ? "0" + d : d; var str = today.getFullYear() + "-" + mm + "-" + dd; $("#source_time").val(str);?
当然,我这里的需求比较死板,固定格式为 yyyy-mm-dd,如果需要灵活的变换格式,可以参考下面的文章

老外写的一个javascript下Date格式化函数?http://blog.csdn.net/akunshenjk/article/details/2539638
PS:发现上面链接的提供的源代码中正则表达式有误,还是看下面的好?http://www.4ucode.com/Study/Topic/1174473
下面贴出代码:
?
Date.prototype.format = function(mask) { var d = this; var zeroize = function (value, length) { if (!length) length = 2; value = String(value); for (var i = 0, zeros = ''; i < (length - value.length); i++) { zeros += '0'; } return zeros + value; }; // return mask.replace(/"[^"]*"|'[^']*'|/b(?:d{1,4}|m{1,4}|yy(?:yy)?|([hHMstT])/1?|[lLZ])/b/g, function($0) { return mask.replace(/"[^"]*"|'[^']*'|\b(?:d{1,4}|m{1,4}|yy(?:yy)?|([hHMstT])\1?|[lLZ])\b/g, function($0) { switch($0) { case 'd': return d.getDate(); case 'dd': return zeroize(d.getDate()); case 'ddd': return ['Sun','Mon','Tue','Wed','Thr','Fri','Sat'][d.getDay()]; case 'dddd': return ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'][d.getDay()]; case 'M': return d.getMonth() + 1; case 'MM': return zeroize(d.getMonth() + 1); case 'MMM': return ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'][d.getMonth()]; case 'MMMM': return ['January','February','March','April','May','June','July','August','September','October','November','December'][d.getMonth()]; case 'yy': return String(d.getFullYear()).substr(2); case 'yyyy': return d.getFullYear(); case 'h': return d.getHours() % 12 || 12; case 'hh': return zeroize(d.getHours() % 12 || 12); case 'H': return d.getHours(); case 'HH': return zeroize(d.getHours()); case 'm': return d.getMinutes(); case 'mm': return zeroize(d.getMinutes()); case 's': return d.getSeconds(); case 'ss': return zeroize(d.getSeconds()); case 'l': return zeroize(d.getMilliseconds(), 3); case 'L': var m = d.getMilliseconds(); if (m > 99) m = Math.round(m / 10); return zeroize(m); case 'tt': return d.getHours() < 12 ? 'am' : 'pm'; case 'TT': return d.getHours() < 12 ? 'AM' : 'PM'; case 'Z': return d.toUTCString().match(/[A-Z]+$/); // Return quoted strings with the surrounding quotes removed default: return $0.substr(1, $0.length - 2); } }); };?
