    marker.setLabelContent("sdda");

please can anybody let me know what's wrong in my code?

Answer 1

Try:

marker.set('labelContent', 'sdda');

Reading through the marker label source code , the MarkerLabel object extends from google.maps.Marker.

Whenever you call the .set() method on the MarkerLabel object, an event is raised which refreshes the marker.

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()

Here is an excerpt from the source code:

@class This class represents the optional parameter passed to the {@link MarkerWithLabel} constructor. The properties available are the same as for google.maps.Marker with 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) .

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