Answer 1

way 2:<table id="aaa">
    <tr >
          <td>1
          </td>
          <td>2
          </td>
          <td onclick="func301(this)">3
          </td>
    </tr >
        <tr >
          <td>a
          </td>
          <td>a
          </td>
          <td onclick="func301(this)">3
          </td>
    </tr >
</table>function func301(a){
    alert("123");
    alert(a.parentNode.childNodes[0].innerText);
    alert(a.parentNode.childNodes[1].innerText);
}

Answer 2

onclick='alert("行：" + (this.parentElement.rowIndex+1) + "\n列：" + (this.cellIndex+1))'

Answer 3

<table border=1 id="aaa">
    <tr>
          <td>12
          </td>
          <td>22
          </td>
          <td>32
          </td>
    </tr >
        <tr >
          <td>a2
          </td>
          <td>a2
          </td>
          <td>32
          </td>
    </tr >
     <tr >
          <td>a2
          </td>
          <td>a2
          </td>
          <td>32
          </td>
    </tr >
     <tr >
          <td>a2
          </td>
          <td>a2
          </td>
          <td>32
          </td>
    </tr >
     <tr >
          <td>a22
          </td>
          <td>a22
          </td>
          <td>322
          </td>
    </tr >
</table><script language=vbscript>
Sub aaa_onClick()
    dim obj,check
'得到产生事件的控件'用事件冒泡得到产生事件的行
    Set obj=window.event.srcElement
    Do 
If   obj.tagname="TABLE" Then Exit sub 
 If obj.tagname="TR" Then  Exit Do   
 Set obj= obj.parentElement
     Loop
   dim i ,j
   i = obj.rowIndex'得到它在表格中的INDEX
   if i < 2 then exit sub
  dim str  msgbox " 上一行第一列的内容为:" & aaa.rows(i - 1).cells(0).innertext
  msgbox " 上上一行第一列的内容为:" & aaa.rows(i - 2).cells(0).innertext
end sub
</script>

Answer 4

<table border=1>
<tr>
<th>td01</th>
<th>td02</th>
<th>td03</th>
</tr>
<tr>
<td>11</td>
<td>22</td>
<td>33</td>
</tr>
<tr>
<td>44</td>
<td>55</td>
<td>66</td>
</tr>
<tr>
<td>77</td>
<td>88</td>
<td>99</td>
</tr>
</table>
<script language="javascript">
document.onclick=function()
{
var obj=event.srcElement;
if(obj.tagName=="TD" && obj.parentNode.tagName=="TR")
{
alert(parseInt(obj.parentNode.rowIndex+1)+"行"+parseInt(obj.cellIndex+1)+"列,数据："+obj.parentNode.childNodes[0].innerText+"\t"+obj.parentNode.childNodes[1].innerText);
}
}
</script>

Answer 5

上面if条件为：if(obj.tagName=="TD" && obj.parentNode.tagName=="TR" && obj.cellIndex==2)点第三列触发。

Answer 6

<table>
<tr>
  <td onClick='alert(which.cellIndex); alert(which.rowIndex);'>aaa</td>
  <td onClick='alert(which.cellIndex); alert(which.rowIndex);'>aaa</td>
  <td onClick='alert(which.cellIndex); alert(which.rowIndex);'>aaa</td>
</tr>
<tr>
  <td onClick='alert(which.cellIndex); alert(which.rowIndex);'>aaa</td>
  <td onClick='alert(which.cellIndex); alert(which.rowIndex);'>aaa</td>
  <td onClick='alert(which.cellIndex); alert(which.rowIndex);'>aaa</td>
</tr>
<tr>
  <td onClick='alert(which.cellIndex); alert(which.rowIndex);'>aaa</td>
  <td onClick='alert(which.cellIndex); alert(which.rowIndex);'>aaa</td>
  <td onClick='alert(which.cellIndex); alert(which.rowIndex);'>aaa</td>
