<body>
<!--External table-->
<table border="1px">
<tr>

<td>
//price and quantity fields
<input type="text" name="price" label="Price" id="Pri">
<input type="text" name="quantity" label="Quantity" id="Qty">
</td>
<td>
<!--internal table-->
<table border="1px">
<tr>
<th>Price</th>
<th>Quantity</th>
<th>Action</th>
</tr>
<tr>
<td>1</td>

<td><input type="checkbox" id="checx"/></td>

<tr>

<td>22</td>
<td><input type="checkbox" id="checx"/></td>

<tr>
<td>111</td>
<td>222</td>
<td><input type="checkbox" id="checx"/></td>
</tr>
<tr>
<td>10</td>
<td>20</td>
<td><input type="checkbox" /></td>
</tr>
</table>
</td>
</tr>

</table>
//Javascript
<script type="text/javascript">
checkboxes = document.getElementById("checx").getElementsByTagName("input");
for (var i = 0; i < checkboxes.length; i++) {
var checkbox = checkboxes[i];
checkbox.onclick = function() {
var currentRow = this.parentNode.parentNode;
var secondColumn = currentRow.getElementsByTagName("td")[1];
var FirstColumn = currentRow.getElementsByTagName("td")[0];
alert("My text is: " + secondColumn.textContent +" "+ FirstColumn.textContent);
};
}
document.getElementById("Pri").value=secondColumn.textContent;
document.getElementById("Qty").value=FirstColumn.textContent;

</script>
//I have a dynamic table on the above pattern.I want in such a way that when I click on the checkbox on the internal table it should copy the values and should show on the input boxes on the corresponding row on the external table.
</body>
</html>

我有一个关于上述模式的动态表。我希望这样一种方式,当我单击内部表上的复选框时,它应该复制值并应该显示在外部表上相应行的输入框中.

感谢您提前提供的帮助

最佳答案

主要问题是每个元素的复选框 ID 必须是唯一的,因此您必须依赖类名而不是复选框的 ID除了以下代码

document.getElementById("Pri").value=secondColumn.textContent;
document.getElementById("Qty").value=FirstColumn.textContent;

必须位于事件处理程序内部

<!DOCTYPE html>
<html>
<body>
<!--External table-->
<table id="parentTable" border="1px">
<tr>

<td>
//price and quantity fields
<input type="text" name="price" label="Price" id="Pri">
<input type="text" name="quantity" label="Quantity" id="Qty">
</td>
<td>
<!--internal table-->
<table border="1px">
<tr>
<th>Price</th>
<th>Quantity</th>
<th>Action</th>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td><input type="checkbox" id="checx1" class="checx"/></td>
</tr>
<tr>
<td>11</td>
<td>22</td>
<td><input type="checkbox" id="checx2" class="checx"/></td>
</tr>
<tr>
<td>111</td>
<td>222</td>
<td><input type="checkbox" id="checx3" class="checx"/></td>
</tr>
<tr>
<td>10</td>
<td>20</td>
<td><input type="checkbox" id="checx4" class="checx" /></td>
</tr>
</table>
</td>
</tr>

</table>
//Javascript
<script type="text/javascript">
checkboxes = document.getElementsByClassName("checx");
for (var i = 0; i < checkboxes.length; i++) {
var checkbox = checkboxes[i];
checkbox.onclick = function() {
var currentRow = this.parentNode.parentNode;
var secondColumn = currentRow.getElementsByTagName("td")[1];
var FirstColumn = currentRow.getElementsByTagName("td")[0];
alert("My text is: " + secondColumn.textContent +" "+FirstColumn.textContent);
document.getElementById("Pri").value=secondColumn.textContent;
document.getElementById("Qty").value=FirstColumn.textContent;
};
}
</script>
</body>
</html>
