前几天做项目,需要用到一种自动增加一行的效果。

<html>

<head>
<title>js-sample</title>

<script type="text/javascript">
<!--
var count = 1;
function add() {
  var tbl = document.all.ci;
  var rows = tbl.rows.length;
  var tr = tbl.insertRow(rows);
   
  var name = tr.insertCell(0);
  name.innerHTML = '<input type="text">';
  var tel = tr.insertCell(1);
  tel.innerHTML = '<input type="text">';
  var rdo = tr.insertCell(2);
  rdo.innerHTML = '<input type="radio" value="0" name="rdo' + count + '">Yes <input type="radio" value="1" name="rdo' + count + '">No';
  var chk = tr.insertCell(3);
  chk.innerHTML = '<input type="checkbox" value="0" name="chk' + count + '">Modify <input type="checkbox" value="1" name="chk' + count + '">Delete';
  var del = tr.insertCell(4);
  del.innerHTML = '<input type="button" onclick="del(this)" value="Delete">';
  count++;
}

function del(btn) {
  var tr = btn.parentElement.parentElement;
  var tbl = tr.parentElement;
  tbl.deleteRow(tr.rowIndex-1);
}
//-->
</script>
</head>

<body>

<input type="button" onclick="add()" value="Add-Customer">

<table border="1" style="width:100%" id="ci" name="ci">
  <caption>customer information</caption>
  <thead>
  <tr>
  <th>Name</th>
  <th>Tel</th>
  <th>Radio</th>
  <th>CheckBox</th>
  <th> </th>
  </tr>
  </thead>
  <tbody>
  <tr>
  <td><input type="text" value="Zhang San"></td>
  <td><input type="text" value="111"></td>
  <td>
  <input type="radio" value="0" name="rdo">Yes <input type="radio" value="1" name="rdo">No
  </td>
  <td>
  <input type="checkbox" value="0" name="chk">Modify <input type="checkbox" value="1" name="chk">Delete
  </td>
  <td>
  <input type="button" onclick="del(this)" value="Delete">
  </td>
  </tr>
  </tbody>
</table>

</body></html>
