L.CircleMarker
L.Path
从not扩展L.Marker
,所以如果你比较https://github.com/Leaflet/Leaflet.label/blob/master/src/Path.Label.js和https://github.com/Leaflet/Leaflet.label/blob/ master/src/Marker.Label.js你会发现Path
没有任何选项,这个逻辑你必须自己实现。例如:
L.CircleMarker.include({
bindLabel: function (content, options) {
if (!this._label || this._label.options !== options) {
this._label = new L.Label(options, this);
}
this._label.setContent(content);
this._labelNoHide = options && options.noHide;
if (!this._showLabelAdded) {
if (this._labelNoHide) {
this
.on('remove', this.hideLabel, this)
.on('move', this._moveLabel, this);
this._showLabel({latlng: this.getLatLng()});
} else {
this
.on('mouseover', this._showLabel, this)
.on('mousemove', this._moveLabel, this)
.on('mouseout remove', this._hideLabel, this);
if (L.Browser.touch) {
this.on('click', this._showLabel, this);
}
}
this._showLabelAdded = true;
}
return this;
},
unbindLabel: function () {
if (this._label) {
this._hideLabel();
this._label = null;
this._showLabelAdded = false;
if (this._labelNoHide) {
this
.off('remove', this._hideLabel, this)
.off('move', this._moveLabel, this);
} else {
this
.off('mouseover', this._showLabel, this)
.off('mousemove', this._moveLabel, this)
.off('mouseout remove', this._hideLabel, this);
}
}
return this;
}
});
L.circleMarker([53.902257, 27.541640] ,{title: 'unselected'}).addTo(map).bindLabel('Destination', { noHide: true });
