我知道這個問題之前已被問及我已經遵循了幾個答案，但似乎沒有工作。我得到的最接近是這樣一個this.setValues是不是一個函數谷歌地圖API 3
Map Markers Not Displaying (JavaScript/Google Maps API V3)
但在這裏，我不知道他想要做的，但是我覺得我的情況是不同的，並沒有爲我工作。 所以請任何人有任何sugeestions請告訴我。
function initialize() {
var mapOptions = {
zoom: 16,
center: new google.maps.LatLng(52.5498783, 13.425209099999961),
mapTypeId: google.maps.MapTypeId.SATELLITE
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
overlay = new DraggableOverlay(map,
map.getCenter(),
'<div class="overlay">drag me!</div>'
);
}
DraggableOverlay.prototype = new google.maps.OverlayView();
DraggableOverlay.prototype.onAdd = function() {
var container = document.createElement('div'),
that = this;
if (typeof this.get('content').nodeName !== 'undefined') {
container.appendChild(this.get('content'));
}
else {
if (typeof this.get('content') === 'string') {
container.innerHTML = this.get('content');
}
else {
return;
}
}
container.style.position = 'absolute';
container.draggable = true;
google.maps.event.addDomListener(this.get('map').getDiv(),
'mouseleave',
function() {
google.maps.event.trigger(container, 'mouseup');
}
);
google.maps.event.addDomListener(container,
'mousedown',
function (e) {
this.style.cursor = 'move';
that.map.set('draggable', false);
that.set('origin', e);
that.moveHandler = google.maps.event.addDomListener(that.get('map').getDiv(),
'mousemove',
function (e) {
var origin = that.get('origin'),
left = origin.clientX - e.clientX,
top = origin.clientY - e.clientY,
pos = that.getProjection()
.fromLatLngToDivPixel(that.get('position')),
latLng = that.getProjection()
.fromDivPixelToLatLng(new google.maps.Point(pos.x - left,
pos.y - top));
that.set('origin', e);
that.set('position', latLng);
that.draw();
});
}
);
google.maps.event.addDomListener(container, 'mouseup', function() {
that.map.set('draggable', true);
this.style.cursor = 'default';
google.maps.event.removeListener(that.moveHandler);
});
this.set('container', container)
this.getPanes().floatPane.appendChild(container);
};
function DraggableOverlay(map, position, content) {
if (typeof draw === 'function') {
this.draw = draw;
}
this.setValues({
position: position,
container: null,
content: content,
map: map
});
}
DraggableOverlay.prototype.draw = function() {
var pos = this.getProjection().fromLatLngToDivPixel(this.get('position'));
this.get('container').style.left = pos.x + 'px';
this.get('container').style.top = pos.y + 'px';
};
DraggableOverlay.prototype.onRemove = function() {
this.get('container').parentNode.removeChild(this.get('container'));
this.set('container', null)
};
google.maps.event.addDomListener(window, 'load', initialize);html, body, #map-canvas {
height: 100%;
margin: 0px;
padding: 0px
}
.overlay{
background:yellow;
padding:30px;
border:4px double black;
}<div id="map-canvas"></div>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyD7FTNE22Wl6S6DTQF83sTZTqbFFPzEkmU&libraries=drawing,places,geometry&callback=initialize">
</script>所以在這裏你可以看到我得到兩個問題
- 谷歌沒有定義
- this.setValues不是一個函數
所以如果有人遇到這個問題，請讓我知道。
