Try:
尝试：
marker.set('labelContent', 'sdda');
Reading through the marker label source code, the MarkerLabel object extends from google.maps.Marker.
通过读取标记标签的源代码，所述物体MarkerLabel从google.maps.Marker延伸。
Whenever you call the .set()method on the MarkerLabel object, an event is raised which refreshes the marker.
每当您.set()在 MarkerLabel 对象上调用该方法时，都会引发一个刷新标记的事件。
So calling marker.set('labelContent', 'sdda');will raise a 'labelcontent_changed'event, which in turn makes the marker set it's inner content this.setContent()
所以调用marker.set('labelContent', 'sdda');将引发一个'labelcontent_changed'事件，这反过来又使标记设置它的内部内容this.setContent()
Here is an excerpt from the source code:
以下是源代码的摘录：
@class This class represents the optional parameter passed to the {@link MarkerWithLabel} constructor.
The properties available are the same as for google.maps.Markerwith the addition of the properties listed below. To change any of these additional properties after the labeled
marker has been created, call google.maps.Marker.set(propertyName, propertyValue).
@class 此类表示传递给 {@link MarkerWithLabel} 构造函数的可选参数。google.maps.Marker除了下面列出的属性外，可用的属性与 for 相同。要在创建标记标记后更改任何这些附加属性，请调用google.maps.Marker.set(propertyName, propertyValue)。

Try: var label= { color: '#333', fontWeight: 'bold', fontSize: '16px', text: data[i].deviceID.toUpperCase() }; marker.setLabel(label);
试试： var label= { color: '#333', fontWeight: 'bold', fontSize: '16px', text: data[i].deviceID.toUpperCase() }; 标记.setLabel（标签）；
