Click on HTML table and get row number (with Javascript, not jQuery)

Question

I would like to know how to click on a button in an HTML table and get the row and column number returned to me: For example, with the following table:

<table>
  <tr>
    <td><input type="button" value="button"></td>
    <td><input type="button" value="button"></td>
    <td><input type="button" value="button"></td>
    </tr>
    <tr>
    <td><input type="button" value="button"></td>
    <td><input type="button" value="button"></td>
    <td><input type="button" value="button"></td>
    </tr>
    <tr>
    <td><input type="button" value="button"></td>
    <td><input type="button" value="button"></td>
    <td><input type="button" value="button"></td>
    </tr>
  </table>

Answer 1

Try this:

 function getId(element) { alert("row" + element.parentNode.parentNode.rowIndex + " - column" + element.parentNode.cellIndex); }

 <table> <tr> <td><input type="button" value="button" onclick="getId(this)"></td> <td><input type="button" value="button" onclick="getId(this)"></td> <td><input type="button" value="button" onclick="getId(this)"></td> </tr> <tr> <td><input type="button" value="button" onclick="getId(this)"></td> <td><input type="button" value="button" onclick="getId(this)"></td> <td><input type="button" value="button" onclick="getId(this)"></td> </tr> <tr> <td><input type="button" value="button" onclick="getId(this)"></td> <td><input type="button" value="button" onclick="getId(this)"></td> <td><input type="button" value="button" onclick="getId(this)"></td> </tr> </table>
