function jsCopy(){
var e=document.getElementsByName("contents");
var i;
var str = "";
for(i=0;i < e.length ; i++){
if(i==0){
str += e[i].value;
}else if(i==1 || i==3){
str += "\t";
str += e[i].value;
}else if(i==2){
str += "\n";
str += e[i].value;
}
}
var sel=document.getElementById("submitTextArea");
sel.value=str;
sel.select();
document.execCommand("Copy");
}
</script>
