如果table是动态生成的呢？ 怎么定位到哪一个单元格？

假设x是行号，y是列号（这里都是从0开始的）document.getElementById("tableid").getElementsByTagName("tr")[x].getElementsByTagName("td")[y]

Answer 3

var  obj  = document.createElement("object");
   obj.id="obj1";
   obj.classid =  "CLSID:C393d31-2d6A-42FA-83C1-C30C37A8D";
   obj.style... document.body.appendChild(obj)

<table class="selfdefineTable" id="newOption">
                  <tr>
                    <th>控件</th>
                  </tr>
                </table>
                <div class="btnAdd"><a href="javascript:add();">再增加一行</a> </div>
jscodefunction add()
{
       var temp = document.getElementById("newOption");
temp.insertRow(temp.rows.length);
        var trlength=temp.rows.length  ;//索引值
temp.rows.item(trlength -1).insertCell(0);
  var sHTML0 = "<object id=\"obj1\" classid=\"CLSID:C393d31-2d6A-42FA-83C1-C30C37A8D\" style=\"width: 100px; height: 100px\" > ";
temp.rows.item(trlength-1).cells.item(0).innerHTML= sHTML0;
}
