我不知道这是否是最好的解决方案,但它正在工作:创建一个覆盖该geocode
函数的自定义地理编码器类。在那里,您可以覆盖结果函数并将建议应用于结果。
L.CustomGeocoder = L.Control.Geocoder.Nominatim.extend({
suggestions: [],
setSuggestions(arr){
this.suggestions = arr;
},
createSuggestionFromMarker(marker){
this.suggestions.push({name: marker.options.title, center: marker.getLatLng()});
},
getResultsOfSuggestions(query){
var results = [];
this.suggestions.forEach((point)=>{
if(point.name.indexOf(query) > -1){
point.center = L.latLng(point.center);
point.bbox = point.center.toBounds(100);
results.push(point);
}
});
return results;
},
geocode(query, resultFnc, context) {
var that = this;
var callback = function(results){
var sugg = that.getResultsOfSuggestions(query);
resultFnc.call(this,sugg.concat(results));
}
L.Control.Geocoder.Nominatim.prototype.geocode.call(that,query, callback, context);
}
})
然后你必须使用新的 Geocoder 类:
var geocoder = new L.CustomGeocoder({});
var control = L.Routing.control({
waypoints: [],
router: new L.Routing.osrmv1({
language: 'en',
profile: 'car'
}),
geocoder: geocoder
}).addTo(map);
最后,您可以在标记上添加建议,并在or上添加title
选项:createSuggestionFromMarker(marker)
setSuggestions(arr)
var suggestions = [
{
name: 'Test Car 1',
center: [50.27, 19.03]
},
{
name: 'Test Car 2',
center: [50.10, 18.4]
}
];
geocoder.setSuggestions(suggestions);
var marker_work = L.marker([50.27, 19.03], { title: 'MyWork'}).addTo(map);
var marker_home = L.marker([50.10, 18.4], { title: 'MyHome'}).addTo(map);
geocoder.createSuggestionFromMarker(marker_work);
geocoder.createSuggestionFromMarker(marker_home);
更新,使用标记 Ref 而不是修复 latlng
更改这两个函数,然后引用标记,它总是从标记的当前位置开始搜索:
createSuggestionFromMarker(marker){
this.suggestions.push({name: marker.options.title, marker: marker});
},
getResultsOfSuggestions(query){
var results = [];
this.suggestions.forEach((point)=>{
if(point.name.indexOf(query) > -1){
if(point.marker){
point.center = point.marker.getLatLng();
}
point.center = L.latLng(point.center);
point.bbox = point.center.toBounds(100);
results.push(point);
}
});
return results;
},
当您拖动标记时,您可以在演示中对此进行测试
