使这php文件打印结果象

<option value="optionValue">optionResult</option>
<option>.......</option>
<option>.......</option>

添加id=“stockcolor”到每个（a）元素，删除超链接，然后单击javascript，如：

<a id="63" class="colorlink" href="#">
    <img src="https://image.spreadshirt.com/image-server/v1/appearances/63" width="24" height="24" class="cnormal">
</a>

安装jquery（将这一行添加到文档的开头）：

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

然后使用 AJAX

$(document).ready(function(){
    $.ajax({
        type: "post",
        url: "Untitled-3.php?checkshop=266497&checkproducttype=210&stockcolor=" + $('#productColor10474717').val(),
        success: function(data){
            $('select#size').html(data);
    }
    });

    $('a.colorlink').click(function(){
    var stockcolor = $(this).attr('id'),
        checkshop = 266497,
        checkproducttype = 210;

    $.ajax({
        type: "post",
        url: "tshirt_ajax.php?checkshop=" + checkshop + "&checkproducttype=" + checkproducttype + "&stockcolor=" + stockcolor,
        beforeSend: function(){
            $('#productColor10474717').val(stockcolor);
        },
        success: function(data){
            $('select#size').html(data);
            $('#tshirt_image').attr('src', 'https://www.ni-dieu-ni-maitre.com/tshirt_image.php?a=10474717&color=' + stockcolor)
        }
    });

    });
});
