怎么判断一个checkbox已选？
- HTML code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><input type="checkbox" onclick="selectAll()" id="choose_all" value="<?php if?> checked==" checked echo>">全选
我要取value的值，要求已选的时候是0，否则为空。上面的写法不对，求改正！
------解决方案--------------------
仿照着这个写就好了
