Put marker from Google Maps v3 in front of all others

问题

Can somebody help me put the current location in front of all others? I have read about MAX_ZINDEX and setZindex() but I cannot understand it. This is my code:

var latlng = new google.maps.LatLng(lat,lng);
var image = "";
var currentplace = "Ohla Hotel";
var zInd = "";
if( name == currentplace ) {
    image = "../img/hotel_icon.png";
}
else {
    image = "../img/home_icon.png";
}
//alert();
var maxZindex = google.maps.Marker.MAX_ZINDEX;
if( name == currentplace ) {
    zInd = (maxZindex + 1);
}
var locationDescription = this.locationDescription;
var marker = new google.maps.Marker({
    map: map,
    position: latlng,
    title:'pk:'+name,
    MAX_ZINDEX: zInd,
    icon: image
});
bounds.extend(latlng);
setMarker(map, marker, name, locationDescription);

回答1:

MAX_ZINDEXis a constant, not an attribute of a marker.

The relevant MarkerOption is zIndex:

var marker = new google.maps.Marker({
    map: map,
    position: latlng,
    title:'pk:'+name,
    zIndex: zInd,
    icon: image
});

This sets the marker's zIndex attribute to the value you have calculated, which is one more than the API's maximum value.

Most of your code makes sense, but your definition of the MarkerOptionsapi-doc object doesn't make sense. Try changing your marker creation code to this:

var marker = new google.maps.Marker({
    map: map,
    position: latlng,
    title:'pk:'+name,
    zIndex: zInd,
    icon: image
});

Since you have already set the value of zInd higher than google.maps.Marker.MAX_ZINDEX, making this change should place the marker higher in the zIndex and thus above the other markers on the map.
