Bixby 如何在动作脚本中检测设备目标类型？

我希望我的“GetContent”脚本检测设备是否为“watch”，并传递一条指令，从content.json文件中筛选出候选答案，该文件的文本字段长度大于一定数量的字符

content.json格式：

{tags: ["literature"], text: "At once it struck me what quality went to form a man of achievement, especially in literature, and which Shakespeare possessed so enormously -- I mean negative capability, that is, when a man is capable of being in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason. Source: John Keats", image: {url: "images/Shakespeare.jpg"}},

所以逻辑应该是

if (watch) content = short_quotes_only

---

我建议探索

$vivContext

（）

---

设备

属性将允许您查看用户正在使用的设备类型（bixby mobile、bixby tv等），并提供您希望为正在使用的设备显示的数据。

这组代码片段对我很有用：

  device = $vivContext.device
  console.log('device', device)

  if (device == 'bixby-watch' ) { maxlength = 100
  console.log('maxlength is now', maxlength)
  }

然后在稍后的脚本中

//filters entitled content by length of text field in characters

content = content.filter(function(i) { return i.text.length < maxlength;

//按字符文本字段长度筛选标题内容
content=content.filter（函数（i）{返回i.text.length
