我需要使用有限的调查应用程序,并且必须调整提供的代码以满足更高级的功能。
我需要创建一个加权排名问题,以便用户可以选择他们的前三个选项,数据将进入调查应用程序并在调查报告中访问。该应用程序仅支持 2 种类型的问题(文本填写和多项选择),但我可以更改代码,只要它仍将表单数据发送回调查应用程序。
代码已设置,因此它将为每个选项显示一个 0-3 的下拉菜单。现在我想限制用户的选择,让他们只能选择一个“1”“2”或“3”,总共三个选项。理想情况下,如果用户已经为一个选项选择了“2”,并且他们试图为另一个选项选择它,则它将第一个“2”设置为“0”或空白。
这可能与javascript有关吗?如果是这样,是否有人知道可能会显示这样的代码的网站,或者提供足够类似的示例以供我调整?
当前代码在这里:
