角传单搜索控制事件 [英] Angular Leaflet Search control event

问题描述

我有一个AngularJS应用程序，当前正在尝试访问传单搜索控件，但是没有运气.

I have an AngularJS application and I'm currently trying to access the "search_expanded" event of Leaflet Search control but having no luck.

这是我的代码:

angular.module('myApp', [ 'leaflet-directive' ])
       .controller('ShowMapCtrl', ["$scope", "leafletData", function ($scope, leafletData) {
       // some code
            leafletData.getMap().then(function(map) {
                       map.on('search_expanded', function(e){
                            alert("search control expannded"); 
                       });
                   });

推荐答案

search_expanded事件以及L.Control.Search支持的所有其他事件都在实际的控件实例上触发，而不是在地图实例上触发，如您所见.以下示例:

The search_expanded event, and all the other events supported by L.Control.Search are fired on the actual control instance not on the map instance as you can see in the following example:

var controlSearch = new L.Control.Search({
    layer: new L.LayerGroup()
}).on('search_expanded', function () {
    console.log('search_expanded!')
}).addTo(map);
