带有 jquery json 数据的动态列表

Question

如何将以下条件附加到 id = #sellerMetal <ul> 容器，它是一个动态循环列表。

如果 dataJS
productList > 奖牌 > 金牌 = true,
追加<li class="icon"><img src="/img/goldmetal.png"></li>

如果 dataJS
productList.medals.silvermedal = true,
追加<li class="icon"><img src="/img/silvermedal.png"></li>

如果 dataJS
productList > 奖牌 > newshop= true,
追加<li class="icon"><img src="/img/newshop.png"></li>
...
...
...
...
...

这是产品列表。

下面是 Product List Append 的渲染列表。

预期结果：

<div id="List">
<div class="feature_ico">
    <ul id="#sellerMetal" class="icons">
        (Apend to here)
    </ul>
</div>
<div class="feature_ico">
    <ul id="#sellerMetal" class="icons">
        (Apend to here)
    </ul>
</div>
<div class="feature_ico">
    <ul id="#sellerMetal" class="icons">
        (Apend to here)
    </ul>
</div>
<div class="feature_ico">
    <ul id="#sellerMetal" class="icons">
        (Apend to here)
    </ul>
</div>
</div>

下面是示例 sn-p。

以下是我尝试过的代码：comment //Condition is here I have tried 是我提出的条件，它不像预期的那样工作。

如果要附加所有真实条件标记，请将 else if 替换为 if。我保留了控制台日志以检查条件是否正确。
