javascript的範圍

<script lanuage="javascript">
var global="javascript";
test();
funciton test()
{
var local="vbscript"
document.write("the global is"+gloabl+"<br>");
document.write("the local is"+local+"<br>");
}
document.write("local");
</script>
----------------------------------
錯誤local已經釋放掉了，它的範圍是函數範圍內

<script language="javascript">
for(var i  = 0; i < 9; i++)
{
document.write(i+"<br>");
}
document.write(i);
--------------------
i沒有被釋放，它的範圍是定義後的範圍
