我正在嘗試將本地搜索工具添加到Leaflet JS庫,之前我從未使用它,所以不太清楚如何去做。我已經複製了變焦控制是如何工作的,所以我已經加入此額外功能:將LocalSearch工具添加到Leaflet JS庫
L.Control.LocalSearch = L.Class.extend({
onAdd: function (a) {
this._map = a,
this._container = L.DomUtil.create("div", "leaflet-control-zoom"),
this._localSearch = this._createSearch(leafletmapsmarker_L10n.search_form, "leaflet-control-zoom-in", this._map.zoomIn, this._map),
this._container.appendChild(this._localSearch)
},
getContainer: function() {
return this._container
},
getPosition: function() {
return L.Control.Position.BOTTOM_LEFT
},
_createSearch: function (a, b, c, d) {
var e = document.createElement("a");
return e.href = "#",
e.title = a,
e.className = b,
L.Browser.touch || L.DomEvent.disableClickPropagation(e),
L.DomEvent.addListener(e, "click", L.DomEvent.preventDefault),
L.DomEvent.addListener(e, "click", c, d),
e
}
然後啓動這個像這樣:
_initControls: function() {
this.options.searchControl && this.addControl(new L.Control.LocalSearch), this.options.zoomControl && this.addControl(new L.Control.Zoom), this.options.attributionControl && (this.attributionControl = new L.Control.Attribution, this.addControl(this.attributionControl))
},
所以基本上我需要弄清楚如何添加功能的搜索。也許我會以錯誤的方式進行討論,但是我無法在網絡上找到關於此的很多信息,所以有人能幫我解決這個問題嗎?
