Js проверка на поле с 1 функция!

[MontefuckeR]

Написах си тази функция:

function hi(artist){
var pr = document.getElementById(+artist).value.indexOf("<script>")
var artist = document.getElementById(+artist);
if(pr != -1 || artist.maxLength < 0 || artist.value == ""){
document.getElementById(+artist).style.border = "2px solid red";
document.getElementById('submit').disabled = "true";
}
else{
document.getElementById(+artist).style.border = "2px solid green";
document.getElementById('submit').disabled = "";
}
}

обаче искам да се извършва според полето а не за всяко поле да я прекопирам:
<input type="text" name="artist" id="artist" onkeyup="hi(artist)" onkeydown="hi(artist)" />
някъде бъркам ама незнам

<input type="text" name="artist" id="artist" onkeyup="hi('artist')" onkeydown="hi('artist')" />

<input type="text" name="artist" id="tra_la_la" onkeyup="hi('tra_la_la')" onkeydown="hi('tra_la_la')" />
