求高手精简此段代码

JScript code

function play3(i) {    if (i == 1) {        audio.currectTime = 0;        audio.play();        i = i + 1;        setTimeout("play3(2)", 2000);    } else if (i == 2) {        audio.currectTime = 0;        audio.play();        i = i + 1;        setTimeout("play3(3)", 2000);    } else if (i == 3) {        audio.currectTime = 0;        audio.play();        i = i + 1;        setTimeout("play3(4)", 2000);    } else if (i == 4) {        audio.currectTime = 0;        audio.play();        i = i + 1;    }}

JScript code

function play3(i) {    audio.currentTime = 0;    audio.play();    if (i == 1 || i == 2 || i == 3) setTimeout("play(" + (i + 1) + ")", 2000);    i += 1;}
[解决办法]
function play3(i) {
audio.currectTime = 0;
audio.play();
i = i + 1;
if(i != 5){
setTimeout("play3("+i+")", 2000);
}
}

这个意思？
