- <table id="tb1" width="200" border="1" cellpadding="4" cellspacing="0">
- <tr>
- <td height="25">第一行</td>
- </tr>
- <tr>
- <td height="25">第二行</td>
- </tr>
- <tr>
- <td height="25">第三行</td>
- </tr>
- <tr>
- <td height="25">第四行</td>
- </tr>
- <tr>
- <td height="25"><input type="button" name="getTableContent" value="获得表格内容" onclick="getTableContent(this)"></td>
- </tr>
- </table>
如上所示代码，按钮点击事件中传入this对象，此对象就是按钮本身。通过以下方法测试获取表格的数据
- <script language="javascript">
- function getTableContent(node) {
-
- var tr1 = node.parentNode.parentNode;
- alert(tr1.rowIndex);
- alert(tr1.cells[0].childNodes[0].value);
- alert(tr1.cells[0].innerText);
-
- var table = document.getElementById("tb1");
-
- var child = table.getElementsByTagName("tr")[rowIndex - 1];
-
- var text = child.firstChild.innerHTML;
- window.alert("表格第" + rowIndex + "的内容为: " + text);
- }
- </script>
