Javascript 访问唯一的嵌套JSON数组项
我试图深入研究以下数组，以便在解析完所有连接器类型项后将其转换为select选项 目前，我可以获得所需的所有数据，但我希望将返回的每个项目转换为单个字符串，而不是将具有多个连接器类型的项目作为单个项目返回（下面的示例显示了我当前拥有的/想要的。这只显示唯一的类型，因此，如果连接器名称已显示一次，则不要将该名称作为选项再次显示 例如（电流输出）： （显示重复项，具有多个类型的嵌套项不会打断为单行） 期望输出： （仅显示唯一的项目，所有结果都拆分为新行） 带JSON的Pastebin示例：Javascript 访问唯一的嵌套JSON数组项,javascript,json,Javascript,Json,我试图深入研究以下数组，以便在解析完所有连接器类型项后将其转换为select选项 目前，我可以获得所需的所有数据，但我希望将返回的每个项目转换为单个字符串，而不是将具有多个连接器类型的项目作为单个项目返回（下面的示例显示了我当前拥有的/想要的。这只显示唯一的类型，因此，如果连接器名称已显示一次，则不要将该名称作为选项再次显示 例如（电流输出）： （显示重复项，具有多个类型的嵌套项不会打断为单行） 期望输出： （仅显示唯一的项目，所有结果都拆分为新行） 带JSON的Pastebin示例： {
