<html>
<head>
<script language=javascript>
function a(){
var tmp=document.getElementsByTagName( "input ");
var checks=new Array();
if(tmp!=null){
for(var i=0;i <tmp.length;i++){
if(tmp[i].type== "checkbox "){
//checks.push(tmp[i]);
if(tmp[i].checked){
alert(tmp[i].parentNode.parentNode.nextSibling.firstChild.nodeValue);
}
}
}
}
}
</script>
</head>
<body>
<input type=button onclick= "a() " value= "click ">
<table id= "table " border=1>
<tr>
<td align= "center ">

[解决办法]
<script>
var Iobj = document.getElementsByTagName( "input ");
for(var i=0;i <Iobj.length;i++)
{
if(Iobj.type == "checkbox ")
{
if(Iobj[i].checked)
{
alert(Iobj[i].parentNode.parentNode.parentNode.childNodes(1).innerText);
}
}
}
</script>
[解决办法]
function check(name)
{
for(var n=0;n <100;n++)
if(document.all[name+n].checked)
{
alert(document.all[ "ck1 "].parentElement.parentElement.childNodes[1].innerText);
}
}
