JavaScript实现 时间格式转换

JavaScript实现 时间格式转换

手动写个js的function实现时间的格式转换（利用字符串的拼接）

栗子哈：把格式  May  18，2018  06:55:05 Am

              转换成  2018-05-18

function todate(inputstr,showsplit) {
        inputstr = inputstr + ""; 
        var date = "";
        var month = new Array();
        var week = new Array();
        month["Jan"] = 1; month["Feb"] = 2; 
        month["Mar"] = 3;month["Apr"] = 4;
        month["May"] = 5; month["Jan"] = 6; 
        month["Jul"] = 7; month["Aug"] = 8;
        month["Sep"] = 9; month["Oct"] = 10; 
        month["Nov"] = 11; month["Dec"] = 12;
        week["Mon"] = "一"; week["Tue"] = "二"; 
        week["Wed"] = "三"; week["Thu"] = "四";
        week["Fri"] = "五"; week["Sat"] = "六"; week["Sun"] = "日";   
        var str = inputstr.split(" ");
        date = str[2];
        date += showsplit + month[str[0]] +
                     showsplit + str[1].split(",")[0];
        return date;
    }

调用

var date = "May 18, 2018 06:55:05 Am";
todate(date,"-");

inputstr是被转换前的时间字符串date，showsplit是转换后 格式之间的分隔符"-"(当然你也可以用其他的符号)。

举一反三，时间之间格式相互转换，写与之对应的js就行啦。
