js关于复选框问题！

for(j=0;j<50;j++)
{
var aa=document.getElemengByName("check"+i);
if(aa.checked){
aa.value=1;
}
else{
aa.value=0;
}
}

谢谢楼上，但是我没太明白。这样说：
在1.php页面中！<input type="checkbox" name="check1">
<input type="checkbox" name="check2">
<input type="checkbox" name="check3"> <input type="hidden" name="checkbox1">//隐藏
<input type="hidden" name="checkbox2">
<input type="hidden" name="checkbox3">我的意思是：当复选框check1被选中，checkbox1的值就为1
当复选框check2没有被选中，checkbox2的值就为0
应该怎么弄？谢谢楼上！

楼上也不学楼上，，，用这么麻烦的写法<script>
function clicks(thisobj)
{
var checkboxname = thisobj.name.replace("check","checkbox");
document.getElementsByName("checkbox1")[0].value=thisobj.checked?1:0;
}
</script>
<form name="form1">
<input type="checkbox" name="check1" onclick="clicks(this);">
<input type="text" name="checkbox1"> <br>
<input type="checkbox" name="check2" onclick="clicks(this);">
<input type="text" name="checkbox2"> <br>

==。。出了点小错
<script>
function clicks(thisobj)
{
var checkboxname = thisobj.name.replace("check","checkbox");
document.getElementsByName(checkboxname)[0].value=thisobj.checked?1:0;
}
</script>
<form name="form1">
<input type="checkbox" name="check1" onclick="clicks(this);">
<input type="text" name="checkbox1"> <br>
<input type="checkbox" name="check2" onclick="clicks(this);">
<input type="text" name="checkbox2"> <br>
</form>
便于观察，我啊把checkbox的type改成TEXT了

话又说回来，不知道你这么做有什么意义？完全没必要用另一个INPUT来记录CHECKBOX的状态啊

是因为我要在2.php页面中用print_r($_post)输出他的值。只好用隐藏的checkbox来判断到底是选没选？kafly(王者) ，我用你的方法改了一下，但却没有出来结果！麻烦你看一下！
<script>
function clicks(thisobj)
{
var checkboxname = thisobj.name.replace("check"+j,"checkbox"+j);
document.getElementsByName(checkboxname)[0].value=thisobj.checked?1:0;
}
</script>1.php <?
for($i=0;$i<sizeof($tok);$i++)
{
$j=$i+1;
print ("<tr>"<td>$tok[$i]</td><td> <input type=\"checkbox\" name=\"check$j\" value=\"1\"onclick=\"clicks(this)\"> <input type=\"hidden\" name=\"checkbox$j\"></td></tr>");
}
?>在2.php中用print_r($_post);没有输出结果！

我是wadw1103,换了个号。呵呵！

PHP怎么处理表单我就不知道了。
PHP语法不懂。print_r($_post); 你要什么结果

输出数组！其实我就是调用一个js程序，把值传给checkbox1、checkbox2、checkbox3。就可以了

是啊，我那个已经帮你传了。<script>
function clicks(thisobj)
{
var checkboxname = thisobj.name.replace("check"+j,"checkbox"+j);
document.getElementsByName(checkboxname)[0].value=thisobj.checked?1:0;
}
</script>上面内容加到<BODY>前面
你print ("<tr>"<td>$tok[$i]</td><td> <input type=\"checkbox\" name=\"check$j\" value=\"1\"onclick=\"clicks(this)\"> <input type=\"hidden\" name=\"checkbox$j\"></td></tr>");
这一句里onclick前面没空格，后面没分号
应该改成
print ("<tr>"<td>$tok[$i]</td><td> <input type=\"checkbox\" name=\"check$j\" value=\"1\" onclick=\"clicks(this);\"> <input type=\"hidden\" name=\"checkbox$j\"></td></tr>");

不需要这么麻烦！
