复制代码 代码如下:

Date.prototype.format =function(format)
{
    var o = {
            \"M+\" : this.getMonth()+1, //month
            \"d+\" : this.getDate(), //day
            \"h+\" : this.getHours(), //hour
            \"m+\" : this.getMinutes(), //minute
            \"s+\" : this.getSeconds(), //second
            \"q+\" : Math.floor((this.getMonth()+3)/3), //quarter
            \"S\" : this.getMilliseconds() //millisecond
    };
    if(/(y+)/.test(format))
    {   
        format=format.replace(RegExp.$1,(this.getFullYear()+\"\").substr(4- RegExp.$1.length));
    }
    for(var k in o)
    {
        if(new RegExp(\"(\"+ k +\")\").test(format))
        {
            format = format.replace(RegExp.$1,RegExp.$1.length==1? o[k] :(\"00\"+ o[k]).substr((\"\"+ o[k]).length));
        }
    }
    return format;
};
