我從數據庫生成值的列表，像這樣：充分利用列表項的值，並將其命名爲jQuery的AJAX調用
<div class="pure-u-1 pure-u-md-2-5 pure-u-lg-2-5 content-left">
<div id="scroll" class="card">
<a href="javascript:showhide('green')"><h2 class="is-center">green</h2></a>
<ul id="greens" class="card-content-ingredients" style="list-style-type: none;">
<?php
foreach ($greens as $green) {
echo "<li>";
echo "<input type='hidden' class='item_id' value='" . $green['id'] . "' name='" . $green['name'] . "'>";
echo "<span class='item-name-small'>" . $green['name'] . "</span>";
echo "<span class='item-description-menu'>" . $green['description'] . "</span>";
echo "<span class='content-right'>";
echo "</span>";
echo "</li>";
}?>
</ul>
</div>
</div>
而且我試圖抓住被點擊的項目一個jQuery功能轉到另一頁：
<script>
$(document).ready(function(){
$('ul.card-content-ingredients li').click(function(){
var form_data = $(this).serialize();
$.ajax({
url: "add-to-cart.php",
type: "POST",
dataType: "json",
data: form_data,
success: function() {}
});
});
});
</script>
而我很難發送實際的數組。我嘗試通過$(this).attr('id")獲取元素信息，但這並不奏效，我試圖序列化，現在只是抓住吸管。我錯過了什麼？
