请问高手javascript读取table中数据如何赋值给数组！
<script language=javascript>

function fnccheck()
{
t=document.getElementById( "dg ")
var nameArray=new Array();
nameArray[0] =t.rows[0].cells[0].innerText;
var dataArray()=new Array();
dataArray[0]=t.rows[1].cells[0].innerText;
}
</script>
<table id=dg border =1>
<tr>
<td > a1 </td>
<td > a2 </td>
<td > a3 </td>
<td > a4 </td>
<td > a5 </td>
</tr>
<tr>
<td > 28 </td>
<td> 12 </td>
<td > 33 </td>
<td > 25 </td>
<td > 44 </td>
</tr>
</table>
请问高手，以上程序为何不能将值赋给数组，并且可以使用数组得值！多谢了！！！

[解决办法]
<script language=javascript>

function fnccheck()
{
t=document.getElementById( "dg ")
var nameArray=new Array();
nameArray[0] =t.rows[0].cells[0].innerText;
var dataArray=new Array();
dataArray[0]=t.rows[1].cells[0].innerText;
alert(nameArray)
alert(dataArray)
}
</script>
<table id=dg border =1>
<tr>
<td > a1 </td>
<td > a2 </td>
<td > a3 </td>
<td > a4 </td>
<td > a5 </td>
</tr>
<tr>
<td > 28 </td>
<td> 12 </td>
<td > 33 </td>
<td > 25 </td>
<td > 44 </td>
</tr>
</table>
<input type= "button " onclick= "fnccheck() ">
[解决办法]
要调用 fnccheck()

[解决办法]
代码中字符串中间有好多换行，所以不行
[解决办法]
<script language=javascript>
var nameArray = new Array();
var dataArray = new Array();
fnccheck();
var total= new Array(dataArray,nameArray) ;
table1(total,200,20,20,30,400,200, "A ");
table1(total,200,320,20,20,400,250, "B ");
</script>
你在上面的代码调用了fnccheck();这个方法，而这个方法要用到table对象，由于html页面是从上到下顺序加载的，所以，你写在前面的时候table对象还没有产生呢。
