常用的方法

格式化日期

Date()返回格式：

Thu Mar 19 2015 12:00:00 GMT+0800 (中国标准时间)
转成2015-05-19

var formatDate = function (date) {  
    var y = date.getFullYear();  
    var m = date.getMonth() + 1;  
    m = m < 10 ? '0' + m : m;  
    var d = date.getDate();  
    d = d < 10 ? ('0' + d) : d;  
    return y + '-' + m + '-' + d;  
}; 

var formatDateTime = function (date) {  
    var y = date.getFullYear();  
    var m = date.getMonth() + 1;  
    m = m < 10 ? ('0' + m) : m;  
    var d = date.getDate();  
    d = d < 10 ? ('0' + d) : d;  
    var h = date.getHours();  
    var minute = date.getMinutes();  
    minute = minute < 10 ? ('0' + minute) : minute;  
    return y + '-' + m + '-' + d+' '+h+':'+minute;  
};

把2015-03-12 12:00 转换成标准时间

var parserDate = function (date) {  
    var t = Date.parse(date);  
    if (!isNaN(t)) {  
        return new Date(Date.parse(date.replace(/-/g, "/")));  
    } else {  
        return new Date();  
    }  
};
