下面的函数用于查找参考编号然后进行比较,然后如果找到相应的值,则根据输入框修改单元格值。这很好用,但是,如何修改下面的现有函数以捕获
之间的值<td><div>this value here</div></td>
以下是相关的Javascript:
function changeit() {
var valueToFind = $('#number').val();
$('#data > tbody> tr').each(function(index) {
console.log(index);
var firstTd = $(this).find('td:first');
if ($(firstTd).text() == valueToFind) {
console.log("found: " + index + ":" + valueToFind);
$(this).find('td:eq(1)').text($('#item').val());
$(this).find('td:eq(2)').text($('#color').val());
}
})
}
以下是HTML标记:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Language" content="en-us">
</head>
<body>
Number:*
<input type="text" id="number">
<br> Items:
<input type="text" id="item">
<br> Color:
<input type="text" id="color">
<br>
<br>
<input type="button" onclick="changeit()" value="save">
<br>
<table id="data" style="width: 100%" cellspacing="1" class="style1">
<tr>
<td>
<div><b>Number*</b></div>
</td>
<td>
<div><b>items</b></div>
</td>
<td>
<div><b>Colors</b></div>
</td>
</tr>
<tbody>
<tr>
<td>
<div>
<div>123</div>
</div>
</td>
<td>
<div>Boats</div>
</td>
<td>
<div>red</div>
</td>
</tr>
<tr>
<td>
<div>456</div>
</td>
<td>
<div>Vehicles</div>
</td>
<td>
<div>blue</div>
</td>
</tr>
<tr>
<td>
<div>789</div>
</td>
<td>
<div>Motorcycles</div>
</td>
<td>
<div>green</div>
</td>
</tr>
</tbody>
</table>
</body>
</html>

更改
var firstTd = $(this).find('td:first');
到
var firstTd = $(this).find('td:first div');
