为什么加了文中的代码，后面的JAVA SCRIPT就不能用了？

Question

将 <SCRIPT LANGUAGE="JavaScript"> 
<!--------------------------
function OnEnter( field ) { if( field.value == field.defaultValue ) { field.value = ""; } } 
function OnExit( field ) { if( field.value == "" ) { field.value = field.defaultValue; } } 
function check_comment_submit(obj) {
if(obj.memo.value.length<10) {
alert("10 word up");
obj.memo.focus();
return false;
}
return true;
}
//---------------->
</script>
的 <!-------- 和 //---------->  改成 <!--  和 //--> 看看

Answer 1

将你的文件另存为utf-8格式看看

Answer 2

只要把下面的代码删了，就没事了，郁闷
<form method=get name=write action="show.php" onsubmit="return check_comment_submit(this)">
<input type=hidden name=bid value="<?=$bid?>">

Answer 3

在页面提示（对像不支持此属性或方法）
出问题的代码，如下，可在别的页面没问题        <script language='JavaScript' type='text/javascript'>
<!--
   if (!document.phpAds_used) document.phpAds_used = ',';
   phpAds_random = new String (Math.random()); 
   phpAds_random = phpAds_random.substring(2,11);
   document.write ("<" + "script language='JavaScript' type='text/javascript' src='");
   document.write ("http://web/phpad/adjs.php?n=" + phpAds_random);
   document.write ("&amp;what=zone:45");
   document.write ("&amp;exclude=" + document.phpAds_used);
   if (document.referer)
      document.write ("&amp;referer=" + escape(document.referer));
   document.write ("'><" + "/script>");
-->
</script><noscript><a href='http://web/phpad/adclick.php?n=af05231d' target='_blank'><img src='http://web/phpad/adview.php?what=zone:45&amp;n=af05231d' border='0' alt=''></a></noscript>
