客户端读取datagrid单元格数据（编辑状态）的问题？

Question

上面的是客户端源文件中显示的内容。下面的是在javascript中可以得到的数据－》Row.cells[3].innerHTML

Answer 1

读取name为GridWDZL:_ctl3:_ctl0的文本框的值：
function get()
{
var s=document.getElementsByName ('GridWDZL:_ctl3:_ctl0')[0];
if(s==null||typeof(s)=='undefined')
{
  alert('找不到元素');
}
else
{
  alert(s.value)
}
}

Answer 2

to vivianfdlpw() 
document.getElementsByName ('GridWDZL:_ctl3:_ctl0')[0]的值为undefined
在document.getElementsByName ('GridWDZL:_ctl3:_ctl0').outerHTML中有我要的value值
