我想知道是否可以更改默认图标(蓝色),在应用程序初始化时使用另一个自定义图标,我阅读了有关如何更改的信息,但我想要整个应用程序的自定义图标。
HTML
<div ng-controller="CustomizedMarkersController">
<button type="button" class="btn btn-primary padright" ng-click="markers.m1.icon=icon" ng-repeat="(key, icon) in icons">{{ key }}</button>
<leaflet markers="markers" center="lisbon"></leaflet>
</div>
JS
app.controller("CustomizedMarkersController", [ '$scope', function($scope) {
var local_icons = {
default_icon: {},
leaf_icon: {
iconUrl: 'examples/img/leaf-green.png',
shadowUrl: 'examples/img/leaf-shadow.png',
iconSize: [38, 95], // size of the icon
shadowSize: [50, 64], // size of the shadow
iconAnchor: [22, 94], // point of the icon which will correspond to marker's location
shadowAnchor: [4, 62], // the same for the shadow
popupAnchor: [-3, -76] // point from which the popup should open relative to the iconAnchor
},
div_icon: {
type: 'div',
iconSize: [230, 0],
html: 'Using <strong>Bold text as an icon</strong>: Lisbon',
popupAnchor: [0, 0]
},
orange_leaf_icon: {
iconUrl: 'examples/img/leaf-orange.png',
shadowUrl: 'examples/img/leaf-shadow.png',
iconSize: [38, 95],
shadowSize: [50, 64],
iconAnchor: [22, 94],
shadowAnchor: [4, 62]
}
};
angular.extend($scope, {
icons: local_icons
});
angular.extend($scope, {
lisbon: {
lat: 38.716,
lng: -9.13,
zoom: 8
},
markers: {
m1: {
lat: 38.716,
lng: -9.13,
message: "I'm a static marker",
icon: local_icons.default_icon,
},
},
defaults: {
scrollWheelZoom: false
}
});
}]);
从 传单文档,请参阅
Icon.Default
:
要更改默认图标,只需更改
的属性(这是一组L.Icon.Default.prototype.options
)。Icon options
例如,在代码中添加一行:
L.Icon.Default.prototype.options.iconUrl = 'myNewDefaultImage.png';
您可能还想更改视网膜显示器的阴影和 2x 图标,这些图标是使用选项
shadowUrl
和 iconRetinaUrl
设置的。
由于上述解决方案在使用Leaflet-1.7时对我不起作用, 我使用这种方法成功了:
L.Marker.prototype.options.icon = L.icon({
iconUrl: "/path/to/markericon.png",
shadowUrl: "/path/to/markershadow.png"
});
使用此代码自定义绘图插件
var drawPluginOptions = {
position: 'topright',
draw: {
polyline: false,
polygon: false,
circle: false, // Turns off this drawing tool
rectangle: false,
circlemarker: false,
marker: {
title: "markerTest",
icon: new MyCustomMarker()
}
},
edit: {
featureGroup: editableLayers, //REQUIRED!!
remove: false
}
};
并添加到地图
map.on('draw:created', function(e) {
var type = e.layerType,
layer = e.layer;
/*if(layer.title == "Place hospital marker"){
do this...
}*/
editableLayers.addLayer(layer);
});```
mergeOptions
。我认为人们不应该直接破解 prototype
,正如这里许多答案中所述,因为我们正在覆盖库的内部结构,这可能有一天会改变。
L.Icon.Default.mergeOptions(icons)
对于
icons
来说:
icons = { // you can replace with your exact image paths
iconUrl: 'media/images/marker-icon.png',
iconRetinaUrl: 'media/images/marker-icon-2x.png',
shadowUrl: 'media/images/marker-shadow.png',
}
您可以参考图标文档,了解
Icon.default
中设置的icons
上的所有可用选项。
