用JS将输入初始化为当前日期，并且符合java.sql.Date格式
用JS将输入初始化为当前日期，并且符合java.sql.Date格式
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。
?
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 removeddefault:return $0.substr(1, $0.length - 2);}});};??
但这篇文章提供的方法，主要适合老外的使用情况，不太符合中国人的要求。稍作修改，如下所示：
?
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($0) {case 'd':return d.getDate();case 'dd':return zeroize(d.getDate());case 'ddd':return ['日','一','二','三','四','五','六'][d.getDay()];case 'dddd':return ['星期日','星期一','星期二','星期三','星期四','星期五','星期六'][d.getDay()];case 'M':return d.getMonth() + 1;case 'MM':return zeroize(d.getMonth() + 1);case 'MMM':return ['一','二','三','四','五','六','七','八','九','十','十一','十二'][d.getMonth()];case 'MMMM':return ['一月','二月','三月','四月','五月','六月','七月','八月','九月','十月','十一月','十二月'][d.getMonth()];case 'yy':return String(d.getFullYear()).substr(2);case 'yyyy':return d.getFullYear();case 'h':return d.getHours() % 12 || 12;case 'hh':return zeroize(d.getHours() % 12 || 12);case 'H':return d.getHours();case 'HH':return zeroize(d.getHours());case 'm':return d.getMinutes();case 'mm':return zeroize(d.getMinutes());case 's':return d.getSeconds();case 'ss':return zeroize(d.getSeconds());case 'l':return zeroize(d.getMilliseconds(), 3);case 'L':var m = d.getMilliseconds();if (m > 99) m = Math.round(m / 10);return zeroize(m);case 'tt':return d.getHours() < 12 ? '上午' : '下午';case 'TT':return d.getHours() < 12 ? '上午' : '下午';case 'Z':return d.toUTCString().match(/[A-Z]+$/);// Return quoted strings with the surrounding quotes removeddefault:return $0.substr(1, $0.length - 2);}});};??
