status bar 語法一問

例子如下:
<script type="text/javascript">
<!--
function statwords(message){
window.status = message;
}
// -->
</script>

<center>
<form>
<input type="button" VALUE="Write a status bar message" OnClick="statwords('This is my message');">
<input type="button" VALUE="Erase the status bar message" OnClick="statwords(' ');">
</form>
</center>

用 onmouseover, onmouseout event 去改變 hyperlink 在 status bar 上的顯示：

[a href="mypage.htm" onmouseover="window.status='My message'; return true;"
onmouseout="window.status='Ready'; return true;">click here[/a>
