Struts中的checkbox问题急

obj.checked==1来判断。
详应用见 http://www.foresight.com.hk/eshop
administration
<script language=JavaScript>
function count_submit()
{var i=1;
var j=0;
var str="";
var objv;
obj=document.form1;
while(eval('obj.e_id'+i))
{
  obj1=eval('obj.e_id'+i);
  objv=eval('obj.e_id'+i+'.value')
    if (obj1.checked==1) {  j++;   str +=","+objv ;}
  i++;
  }
if (1<=j) {
str=str.substr(1,str.length);
obj.action="/myshop/WS_Mdbman.asp?act=delselect&id_box="+str;
obj.method='post';
obj.submit();
return true;
}
else { alert("No records selected\n");
return 0;}
}
</script>

这个checkbox的值是在ActionClass中做好的一个formBean的List中。然后再jsp中利用
struts的标签库如下：<logic:iterate id="todo" name="processGates" type="toDoForm">
  <html:checkbox name="todo" property="boolean" value="on"
  indexed="true"/>
<logic:iterate/>最后这个值是返回List的formBean中对应的属性（boolean）中。struts的标签库自动会解决这个问题。所以checkbox标签有一个属性indexed
但现在表示该属性不许可。有人用过吗
看看我写的代码
