我正在尝试动态加载一个表单，该表单将从 sql 数据库中的行数填充。数据返回十六进制颜色、名称和价格。我想在表单和 POST 上向用户显示颜色和名称，我想发送附加到该特定颜色的价格。我花了一整天的时间试图弄清楚这一点。

任何帮助将不胜感激！

这是我所拥有的一个例子：http: //hruska-schuman.com/test2/feedback_form.php

代码：

   $query = "SELECT 
     `name`,
     img,
     price
     FROM `gutter`";

            try 
            { 
                    $stmt = $db->prepare($query); 
                $stmt->execute();
            } 
            catch(PDOException $ex) 
            { 
                die("Failed to run query: " . $ex->getMessage()); 
            } 

           $rows = $stmt->fetchAll();  

        $form = 
        '<ol id="selectable" name="selectable">';

        foreach($rows as $row):
        $prices[] = htmlentities($row['price'], ENT_QUOTES, 'UTF-8');
        $form .= '<li class="ui-widget-content" style="background:#'.htmlentities($row['img'], ENT_QUOTES, 'UTF-8').'">'.htmlentities($row['name'], ENT_QUOTES, 'UTF-8').'    Price: '.htmlentities($row['price'], ENT_QUOTES, 'UTF-8').'</li>'; 
        endforeach;

         $form .=' </ol>';

    ?>

使用 JQuery UI 选择表：http: //jqueryui.com/selectable/

我只是不知道如何获取选定的索引并发布“$prices[selectedIndex]”

您应该data-对颜色元素使用自定义属性（如属性）。

        $form .= '<li class="ui-widget-content" style="background:#'.
    htmlentities($row['img'], ENT_QUOTES, 'UTF-8').'"
data-price=".$row['price'].">'.
    htmlentities($row['name'], ENT_QUOTES, 'UTF-8').
    '    Price: '.htmlentities($row['price'], ENT_QUOTES, 'UTF-8').
    '</li>

那么在你的js中你可以做这样的事情：

 $(function() {
        $( "#selectable" ).selectable({
            stop: function() {
                var result = $( "#select-result" ).empty();
                $( ".ui-selected", this ).each(function() {
                    var price = $( "#selectable li" ).attr('data-price');
                    result.append( "" + ( price ) );
                    // or you can set it directly to an input / hidden input
                   $('#price-input').val(price);
                    return price;
                });
            }
        });
    });

哪里#price-input可能是隐藏的输入form：

<input type="hidden" name="selectedPrice" />

当然，您也可以radio为此使用输入。
