我正在尝试使用一个功能,用户可以从下拉框中选择他们想要的项目,然后价格将显示在其侧面的输入框中。
我现在面临的问题是在多行中具有相同的功能。代码如下:
<td class="formiterate" >
<select id="Employee_ID" name="id[]">
<option value="">Select one</option>
<?php
$st = $pdo->prepare("SELECT * FROM tbl_stock");
$st->execute();
$rowes = $st->fetchAll(PDO::FETCH_ASSOC);
foreach ($rowes as $rowe) {
?><option value="<?= $rowe ['id']; ?>"><?= $rowe ['stock_item']; ?> (<?= $rowe ['stock_brand']; ?>)</option><?php
}
?>
</select>
</td>
<td class="formiterate"><input type="text" name="Last_name[]" id="Last_name"></td>
如您所见,当您从Employee_ID
中进行选择时,商品价格将反映在Last_name[]
输入框中。
虽然代码适用于单行,但我无法迭代多行的函数。
以下是我的javascript:
$(function() { // This code will be executed when DOM is ready
$('#Employee_ID').change(function() { // When the value for the Employee_ID element change, this will be triggered
var $row = $(this); // We create an jQuery object with the select inside
$.post("getData.php", { Employee_ID : $row.val()}, function(json) {
if (json && json.status) {
$('#Last_name').val(json.lastname);
}
})
});
})
我尝试在.closest(".rows")
添加var ($row)= $this
,但注意到了。
请帮忙。

一个例子(硬编码示例): -
abc.php: -
<?php
error_reporting(E_ALL); //check all type of errors
ini_set('display_errors',1);
$rowes = array(0=>array('id'=>1,'stock_item'=>'item1','stock_brand'=>'demo1'),1=>array('id'=>2,'stock_item'=>'item2','stock_brand'=>'demo2'),2=>array('id'=>3,'stock_item'=>'item3','stock_brand'=>'demo3'));
?>

<script src = "https://code.jquery.com/jquery-3.1.0.min.js"></script>
<script>
$(function() { // This code will be executed when DOM is ready
$('.Employee_ID').change(function() { // When the value for the Employee_ID element change, this will be triggered
var data = $(this).children(':selected').text();
console.log(data);
$(this).parent().next().find('.Last_name').val(data);
});
})

我的结果输出(从下拉列表中选择后): - http://prntscr.com/chernw
注意: - 将此代码放入单独的文件并运行。那么你就可以理解你要做什么,然后相应地改变你的代码。谢谢。
在你的情况下尝试这样: -
$(function() { // This code will be executed when DOM is ready
$('.Employee_ID').change(function() { // When the value for the Employee_ID element change, this will be triggered
var currentseletbox = $(this);
var data = $(this).children(':selected').text();
$.post("getData.php", { Employee_ID : $row.val()}, function(json) {
if (json && json.status) {
currentseletbox.parent().next().find('.Last_name').val(json.lastname);
}
});
});
})
