过去一个月我一直在制作产品配置器，并从Stackoverflow获得了一些非常棒的帮助。我回来寻求一些帮助。在继续之前，我已经谷歌寻求答案，查看Stackoverflow，并尝试自己搞乱代码。我也是编码的新手，所以我知道代码并不完美。
无论如何，我的代码通过从下拉列表或复选框中选择一个选项来工作，并将其值放在最后的输入文本框中。 我想要实现的是在“选项”部分（这些都是复选框）中，我希望值在选中时出现在名为“completeText”的输入文本框中，并在未选中时消失。 我找到了一些效果很好的代码，但是如果我在“选项”之前选中了所有下拉菜单，然后选中了一个复选框，它会清除整个框，但该复选框的值除外。 我需要复选框值附加到其他下拉选项。最后的部件号应该是相互附加的所有值，用“ - ”分隔。再次，我尝试了很多不同的方法来实现这一点，到目前为止一直没有成功。任何方向或帮助都将是奇妙的！非常感谢你，如果有人想帮助我的HTML / JS以供参考（警告长代码）：
