getData

```getData()```函数返回当前线程环境中储存的键-值对中```key```参数对应的键值。

string、number、bool、object、array、空值等系统支持的所有类型


getData()
getData(key)

```key```参数为储存的键-值对的键名。

key
true
string

```javascript
function main() {
    var t1 = threading.Thread(function() {
        for (var i = 0; i < 5; i++) {
            threading.currentThread().setData("count", i)
            Log(`setData("count"):`, i)
            Sleep(1000)
        }
    })
    for (var i = 0; i < 5; i++) {
        var count = threading.getThread(t1.id()).getData("count")
        Log(`getData("count"):`, count)
        Sleep(1000)
    }
    t1.join()
}

在并发线程的环境中记录键名为count的值，然后在主线程中读取count的键值。
