是可以用document.getElementById()的,不过要注意执行顺序,只要把textarea放在最上面先执行就可以了。
因为字符串中有换行,所以不能直接写在JS里。

在脚本中获得把从服务器(jsp)中传来的有换行符的字符串,判断里面有没有某一个子串,如果有,才在页面显示的一个控件里另外一个数据,所以我必须在页面生成之前执行脚本,而不是先显示在一个textarea里,再用document.getElementById()取出来。javascript有解决的办法嘛?
<script >
var a="<%=CommStr.jsEncoder(serverStr)%>";
alert(a);
</script>
<input name=a value="<%=CommStr.htmlEncoder(serverStr)%>">
