[```ThreadRet```对象](https://www.fmz.com/syntax-guide/struct/otherstruct/Thread.join-return)包含执行结果的相关数据，包含的属性如下：
- id: 线程Id。
- terminated: 线程是否被强制结束。
- elapsed: 线程的运行时间(纳秒)。
- ret: 线程函数的返回值。
```ThreadRet```对象
join()
join(timeout)
```timeout```参数用于设置等待线程结束的超时时间，单位为毫秒。```timeout```参数设置为0或者不设置```timeout```参数时```join()```函数会阻塞，等待到线程执行结束。```timeout```参数设置为-1时，```join()```函数会立即返回。
timeout
false
number
```javascript
function main() {
var t1 = threading.Thread(function() {
Log("Hello thread1")
Sleep(5000)
})
var ret = t1.join(1000)
Log("ret:", ret) // ret: undefined
ret = t1.join()
Log("ret:", ret) // ret: {"id":1,"terminated":false,"elapsed":5003252000}
}
テストjoin()函数が終了すると,出力値が返されます.
join()この関数には,undefined。
