如何在Google Maps API v3中设置标记的z-index

Question

任何人都可以解释使用Google Maps API（第3版）为标记设置z-index的确切语法吗？

Answer 1

In the MarkerOptions :

var marker = new google.maps.Marker({ 
    ....
    zIndex: 100 
});

Or via the Marker setter:

marker.setZIndex(100);

Answer 2

zIndex is actually a relative term. For example, if you have two markers, marker1 and marker2, and the zIndex of marker1 is 100 and the zIndex of marker2 is 101: it means that marker2 is higher in the stack than marker1. As a result, marker2 will be on top or marker1, and in front of the user.

You can set the z-index using :

var marker=new google.maps.Marker({
    position: myCenter,
    map: map,
    zIndex: 100
});

If you have previously created a marker, then just use:

marker.setZIndex(101);
