我创建了一个带有下拉菜单的表格,将用作比较图表。当用户从下拉列表中选择产品时,下面列中的单元格将填充存储在数组中的产品详细信息。
到目前为止,这工作得很好,但是我在向脚本添加 if/else 语句时遇到了问题,这样我们不仅可以监听 col2 的下拉列表,还可以检测 col3 或 col4 的产品选择。
$(".select2").change(function() {
var jthis = $(this);
var whichCol;
if (jthis.hasClass("col2")) {
whichCol = "col2";
}
正如您现在所看到的,我正在收听下拉菜单“select2”中的更改,该下拉菜单具有 col2 类,然后使用 ID col2 写入 td。我无法击败我如何使脚本也检测到 col3 和 col4 的更改。

我还想更改“徽标”的 jQuery,以更改图像的 src,例如产品徽标。我一直在查看 Stack Overflow 和其他一些网站,但无法自己解决这两个问题中的任何一个......是的,我不是一个大的 Java 专家,但非常感谢任何帮助。
代码也在我的 jsfiddle上
