目前我正在使用原始代码示例,甚至无法使其正常工作!
我调用创建标记的函数,如下所示...
overlay = new CustomMarker(new google.maps.LatLng(subitem[2], subitem[3]), mapView);
overlay.setMap(mapView);
这里是 CustomMarker 的代码:
function CustomMarker(latlng, map) {
google.maps.OverlayView.call(this);
this.latlng_ = latlng;
// Once the LatLng and text are set, add the overlay to the map. This will
// trigger a call to panes_changed which should in turn call draw.
this.set_map(map);
}
CustomMarker.prototype = new google.maps.OverlayView();
CustomMarker.prototype.draw = function() {
var me = this;
// Check if the div has been created.
var div = this.div_;
if (!div) {
// Create a overlay text DIV
div = this.div_ = document.createElement('DIV');
// Create the DIV representing our CustomMarker
div.style.border = "0px solid none";
div.style.position = "absolute";
div.style.paddingLeft = "0px";
div.style.cursor = 'pointer';
var img = document.createElement("img");
img.src = "../../images/tile_images/ship_black_0.png";
div.appendChild(img);
google.maps.event.addDomListener(div, "click", function(event) {
google.maps.event.trigger(me, "click");
});
// Then add the overlay to the DOM
var panes = this.get_panes();
panes.overlayImage.appendChild(div);
}
// Position the overlay
var point = this.get_projection().fromLatLngToDivPixel(this.latlng_);
if (point) {
div.style.left = point.x + 'px';
div.style.top = point.y + 'px';
}
};
CustomMarker.prototype.remove = function() {
// Check if the overlay was on the map and needs to be removed.
if (this.div_) {
this.div_.parentNode.removeChild(this.div_);
this.div_ = null;
}
};
CustomMarker.prototype.get_position = function() {
return this.latlng_;
};
使用相同的LatLng和mapView创建标准标记是没有问题的。我得到的错误是:
TypeError:表达式“this.set_map”[未定义]不是一个函数。
