【问题描述】：

我有一个名为 kasaScenes 的函数和特定的嵌套“场景”函数，它们根据我需要激活的“场景”执行 POST。（例如：sceneTooCold、sceneTooHot 等）。因此，稍后在该过程中，将传感器的温度与阈值进行比较，如果它符合特定标准（例如：如果 sensor.temperature

function kasaScenes() {

  function sceneTooCold() {
    post_content_gAC = '{"method":"passthrough","params":{"deviceId":"' + gACID + '","requestData":"{\\"system\\":{\\"set_relay_state\\":{\\"state\\":' + stateOff + '}}}","token":"' + kasa_token + '"}}';
    post_content_gExhaust = '{"method":"passthrough","params":{"deviceId":"' + gExhaustID + '","requestData":"{\\"system\\":{\\"set_relay_state\\":{\\"state\\":' + stateOff + '}}}","token":"' + kasa_token + '"}}';
    post_content_gFans = '{"method":"passthrough","params":{"deviceId":"' + gFansID + '","requestData":"{\\"system\\":{\\"set_relay_state\\":{\\"state\\":' + stateOn + '}}}","token":"' + kasa_token + '"}}';

    post_content_gCeiling = '{"method":"passthrough","params":{"deviceId":"' + gCeilingID + '","requestData":"{\\"system\\":{\\"set_relay_state\\":{\\"state\\":' + stateOn + '}}}","token":"' + kasa_token + '"}}';
    //<~POST Return~>
    returnValue_gAC = KumoApp.httpCallExternal(post_url, "POST", post_content_gAC);
    returnValue_gExhaust = KumoApp.httpCallExternal(post_url, "POST", post_content_gExhaust);

    returnValue_gCeiling = KumoApp.httpCallExternal(post_url, "POST", post_content_gCeiling);

  }

  function sceneTooHot() {

【问题讨论】：

你没有从父函数返回任何东西，所以现在这根本不可能。将父函数转换为具有键/值对的对象，其中键为sceneTooCold、sceneTooHot 等及其值作为相应的函数，或者将kasaScenes 创建为一个类，并将相应的函数作为其方法。
我不明白这个问题。除了if (sensor.temperature < 70) { sceneTooCol(); } else if (sensor.temperature > 100) { sceneTooHot(); } else { sceneNormalTemp(); }，你还需要什么
@rahulpsd18 这是有道理的。我对 js 还很陌生，所以我不知道我需要返回一些东西。我实际上不需要返回任何值，而只需要那个特定部分（我认为应该是一个函数）来运行 POST。感谢您的指导！
@Barmar 所以把它放在外部函数之外的其他地方会起作用吗？我正在尝试，但不断收到“TypeError：'sceneTooDry()' 不是函数”。
不，应该在外层函数里面。

【解决方案1】：

我通过使用@Barmar 提出的建议得到了答案。我没有看到我可以在哪里标记这个回答。

我按照他的建议从外部函数内部调用了内部函数。
