mousedown,mousemove和mouseup的Google Map API V3事件

我正在尝试模仿谷歌地图的谷歌地图中的绘图路径的桌面版本。我所做的是当我尝试绘制路径时,我已禁用默认地图的可拖动事件并附加了一个mousedown事件。在mousedown事件之后,mousemove事件被触发并相应地工作。当鼠标释放时,事件被捕获在mouseup处理程序中,其中mousemove处理程序在mouseup事件侦听器中被删除。但是,在第二次mousedown和mouseup事件之后,这无法正常工作。

我的代码是:

var map = 'Already created map object';
var polyOptions = {
                    strokeColor: '#000000',
                    strokeOpacity: 1.0,
                    strokeWeight: 2,
                    map: map,
                    idx: 0
                };
var mouseMoveHandler = null;
google.maps.event.addListener(map, 'mousedown', function(e) {
  mouseMoveHandler = google.maps.event.addListener(map, 'mousemove', function(e) {
  // Create a new polyline instance if it does not exists
  if ("undefined" == typeof(GMap._poly[GMap._active_overlay])) {
    GMap._poly[GMap._active_overlay] = new google.maps.Polyline(polyOptions);
  }
  var path = GMap._poly[GMap._active_overlay].getPath();
  path.push(e.latLng);
  }); // End of mousemove lister
  return false;
});

google.maps.event.addListener(map, 'mouseup', function(e) {
  google.maps.event.removeListener(mouseMoveHandler);
});

将此添加到polyOptions:

clickable:false

没有这个,多边形将监听鼠标事件,而mouseup-event将在多边形上触发,而不是在地图上触发。

带有bootstrap工具提示的示例:

    google.maps.event.addListener(poly,"mousemove",function(e){

        var _tooltipPolys = $("#tooltipPolys");
        if(_tooltipPolys.length == 0) {
            _tooltipPolys = $(' \
                <div id="tooltipPolys" class="tooltip top" role="tooltip"> \
                    <div class="tooltip-arrow"></div> \
                    <div class="tooltip-inner"></div> \
                </div> \
            ');
            $("body").append(_tooltipPolys);
            $("div.tooltip-inner", _tooltipPolys).text(this.title);
            _tooltipPolys.css({
                "opacity": ".9",
                "position":"absolute"
            });
        }

        var pageX = event.pageX;
        var pageY = event.pageY;
        if (pageX === undefined) {
            pageX = event.clientX + document.body.scrollLeft + document.documentElement.scrollLeft;
            pageY = event.clientY + document.body.scrollTop + document.documentElement.scrollTop;
        }
