我们在项目中一般会遇到显示时间的问题，一般的处理方式是在前台通过JS控制，JS控制显示时间的代码如下，各种不同的显示方式：

复制代码 代码如下:
function Clock() {
var date = new Date();
this.year = date.getFullYear();
this.month = date.getMonth() + 1;
this.date = date.getDate();
this.day = new Array("星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六")[date.getDay()];
this.hour = date.getHours() < 10 ? "0" + date.getHours() : date.getHours();
this.minute = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes();
this.second = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds();

this.toString = function() {
return "现在是:" + this.year + "年" + this.month + "月" + this.date + "日 " + this.hour + ":" + this.minute + ":" + this.second + " " + this.day;
};//现在是<SPAN id=clock>现在是:2013年3月6日 13:54:17 星期三</SPAN>

复制代码 代码如下:
<SPAN></SPAN>
this.toSimpleDate = function() {
return this.year + "-" + this.month + "-" + this.date;
};//2013-03-06

this.toDetailDate = function() {
return this.year + "-" + this.month + "-" + this.date + " " + this.hour + ":" + this.minute + ":" + this.second;
};//2013-03-06 13:45:43

this.display = function(ele) {
var clock = new Clock();
ele.innerHTML = clock.toString();//显示方式调用
window.setTimeout(function() {clock.display(ele);}, 1000);
};
}
