【问题描述】：
我通过使用 PHP 从 SQL 获取数据创建了一个动态表。每行都有一个链接到模态的编辑按钮。我想将值从表传递到模态，以便我可以编辑它。
我尝试循环遍历表行并能够获取不同列的值。但是，每次我单击任何编辑按钮时，只有最后一行被传递到模态输入。
这是我的标记： 模态
<div class="modal fade" id="modalCategory" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog modal-sm" role="document">
<form role="form" method="POST" action="php/add_category.php">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Category</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">

</button>
</div>
<div class="modal-body">
<div class="form-group">

<div class="modal-footer">

表格
<table id="main-table" class="footable table table-stripped toggle-arrow-tiny default breakpoint footable-loaded" data-page-size="15">
<thead>
<tr>
<th data-toggle="true" class="footable-visible footable-first-column footable-sortable">ID<span class="footable-sort-indicator"></span></th>
<th data-hide="phone" class="footable-visible footable-sortable">Category Name<span class="footable-sort-indicator"></span></th>

</tr>
</thead>
<tbody>
<?php foreach($categories as $category){ ?>
<tr class="footable-even" style="">
<td class="footable-visible footable-first-column" id="tdCategoryID"><span class="footable-toggle"></span>
<?php echo $category['categoryID']; ?>
</td>
<td class="footable-visible" id="tdCategory">
<?php echo $cakeOrdering->escape($category['category']); ?>
</td>
<td class="text-right footable-visible footable-last-column">
<div class="btn-group">
<button class="btn-white btn btn-xs">Delete</button>
<button class="btn-white btn btn-xs" data-toggle="modal" data-target="#modalCategory" id="editCategory">Edit</button>
</div>
</td>
</tr>
<?php } ?>
</tbody>
</table>
脚本
<script type="text/javascript">
$(document).ready(function () {
var table = document.getElementById("main-table");
$('#main-table tr').each(function(i, row){
var $row = $(row);
var category = $row.find('td:nth-child(2)').text().trim();
console.log(category);
$('#category').val(category);
});
});
</script>
这是输出 Output
当我尝试将值打印到控制台时。 Console.log
