checkbox控制text的disable，这个可能有点难
因为每行(tr)都是从数据库中提取的，有没有什么好办法，能使用第一个td内的checkbox控制第二个td里的text的disabled状态。这样的dom的操作，哥们还没到那境界，呵呵。~~~~~~~~~~~~~ 谢先了。
下面是我写的片断，大侠可以凑合用。
<script>
function test(){
// some code here .hehe
}
</script>
<BODY onload=test()>
<table>
<tr>
<td> <input name=chk type=checkbox value=a> </td>
<td> <input name=txt type=text value=b> </td>
</tr>
</table>
</BODY>
[解决办法]
<script>
function test(){
// some code here .hehe
var objs=document.getElementById( "table1 ").childNodes[0].childNodes
for(var i=0;i <objs.length;i++)
{
if(objs[i].childNodes[0].childNodes[0].checked)
{
objs[i].childNodes[1].childNodes[0].disabled=true;
}
}
}
</script>
<BODY onload=test()>
<table id= "table1 ">
<tr>
<td> <input name=chk type=checkbox value=a checked> </td>
<td> <input name=txt type=text value=b> </td>
</tr>
<tr>
<td> <input name=chk type=checkbox value=a > </td>
<td> <input name=txt type=text value=b> </td>
</tr>
</table>
</BODY>
[解决办法]
var objs=document.getElementsByTagName( "table ")[0].childNodes[0].childNodes
所有的table都是数组形式
