插件的代碼：
(function($){
$.formatDate = function(pattern,date){
//假設不設置，默覺得當前時間
if(!date) date = new Date();
if(typeof(date) ==="string"){
if(date=="") date = new Date();
else date = new Date(date.replace(/-/g,"/"));
}
/*補00*/
var toFixedWidth = function(value){
var result = 100+value;
return result.toString().substring(1);
};
/*配置*/
var options = {
regeExp:/(yyyy|M+|d+|h+|m+|s+|ee+|ws?|p)/g,
months: ['January','February','March','April','May',
'June','July', 'August','September',
'October','November','December'],
weeks: ['Sunday','Monday','Tuesday',
'Wednesday','Thursday','Friday',
'Saturday']
};
/*時間切換*/
var swithHours = function(hours){
return hours<12?"AM":"PM";
};
/*配置值*/
var pattrnValue = {
"yyyy":date.getFullYear(), //年份
"MM":toFixedWidth(date.getMonth()+1), //月份
"dd":toFixedWidth(date.getDate()), //日期
"hh":toFixedWidth(date.getHours()), //小時
"mm":toFixedWidth(date.getMinutes()), //分鍾
"ss":toFixedWidth(date.getSeconds()), //秒
"ee":options.months[date.getMonth()], //月份名稱
"ws":options.weeks[date.getDay()], //星期名稱
"M":date.getMonth()+1,
"d":date.getDate(),
"h":date.getHours(),
"m":date.getMinutes(),
"s":date.getSeconds(),
"p":swithHours(date.getHours())
};
return pattern.replace(options.regeExp,function(){
return pattrnValue[arguments[0]];
});
};
})(jQuery);
插件使用：
前提要有一個jquery-1.8.3.js
<!-- jquery的使用 -->
<script type="text/javascript" src="jquery-1.8.3.js"/></script>
<script type="text/javascript" src="jquery.dateformat.js"></script>
<script type="text/javascript">
$(function($){
var time = new Date("2014-01-01 13:20:30");
console.info($.formatDate("yyyy-MM-dd hh:mm:ss ws ee","2013-1-1 13:20:30"));
});
</script>
效果：
