    自定义卡片的 Action 事件

    在 Home Assistant Core 2023.7 版本中，我们为自定义卡片引入了 hass-action。

    如果您是自定义卡片开发者，现在可以通过新的 hass-action 在自定义卡片中使用任意卡片 action。

    示例：

    // Define the action config
const actionConfig = {
  entity: "sensor.temperature",
  tap_action: {
    action: "more-info",
  },
  hold_action: {
    action: "assist",
    start_listening: true,
  },
};

// Open more info on tap action
const event = new Event("hass-action", {
  bubbles: true,
  composed: true,
});
event.detail = {
  config: actionConfig,
  action: "tap",
};
this.dispatchEvent(event);

// Open assist dialog on hold action
const event = new Event("hass-action", {
  bubbles: true,
  composed: true,
});
event.detail = {
  config: actionConfig,
  action: "hold",
};
this.dispatchEvent(event);
