谷歌地图标记类别过滤不起作用？

Question

Angularjs谷歌地图类别过滤不起作用。我已经封闭了我的代码。在这里我有使用类别过滤谷歌地图标记。 当我从下拉过滤中选择类别不起作用类别时，我在下拉列表中给出了类别。我附上了小提琴，有人帮我前进https://jsfiddle.net/h9seLt22/2/

 angular.module('myApp', []) .controller('MapCtrl', [ '$scope', '$http', '$compile', function($scope, $http, $compile) { //------------------------------------------------------------------------------------------------------------------------------------------------- $scope.find = function(){ var gmarkers1 = []; var markers1 = []; var infowindow = new google.maps.InfoWindow({ content: '' }); // Our markers markers1 = [ ['0', 'Madivala', 12.914494, 77.560381, 'computer science,electronic system,communication thoery,english','as12','Abi Tech ACC'], ['1', 'Majestic', 12.961229, 77.559281, 'electronic system,Telecommunication,optical&fiber optics','as13','Vell Infotech'], ['2', 'Ecity', 12.92489905, 77.56070772, 'communication thoery,english,Digital Electronics,signal&systems','as14','vinoth coching center'], ['3', 'Jp nagar', 12.91660662, 77.52047465, 'Digital Electronics,signal&systems','as15','Gpy tech archi'] ]; /** * Function to init map */ function initialize() { var center = new google.maps.LatLng(12.9667,77.5667); var mapOptions = { zoom: 12, center: center, mapTypeId: google.maps.MapTypeId.TERRAIN }; map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions); for (i = 0; i < markers1.length; i++) { addMarker(markers1[i]); } } /** * Function to add marker to map */ function addMarker(marker) { var category = marker[4]; var title = marker[1]; var pos = new google.maps.LatLng(marker[2], marker[3]); var content = marker[1]; var fullContent = marker.slice(1,6).join(); var marker1 = new google.maps.Marker({ title: title, position: pos, category: category, map: map }); gmarkers1.push(marker1); // Marker click listener google.maps.event.addListener(marker1, 'click', (function (marker1, idx, markers1) { return function () { console.log('Gmarker 1 gets pushed'); var compiled = '<div><div>' +markers1[idx][0] + ' </div><div>' + markers1[idx][1] + ' </div><div>' +markers1[idx][2] + ' </div><div><button id="' + markers1[idx][5] + '">Get</button></div></div>'; var infowindow = new google.maps.InfoWindow({ content: compiled }); infowindow.open(map, marker1); map.panTo(this.getPosition()); map.setZoom(15); } })(marker1,i, markers1)); } $(document.body).on('click', 'button', function() { console.log(this.id); }); /** * Function to filter markers by category */ filterMarkers = function (category) { console.log(category); for (i = 0; i < markers1.length; i++) { marker = gmarkers1[i]; // If is same category or category not picked if (marker.category.split(',') == category || category.length === 0) { marker.setVisible(true); } // Categories don't match else { marker.setVisible(false); } } } // Init map initialize(); } }]);

试试看： -https : //jsfiddle.net/h9seLt22/6/

JS：-

 filterMarkers = function (category) {
            for (i = 0; i < markers1.length; i++) {
                marker = gmarkers1[i];
                // If is same category or category not picked
                if (marker.category.toLowerCase().indexOf(category.toLowerCase()) > -1 || category.length === 0) {
                    marker.setVisible(true);
                }
                // Categories don't match 
                else {
                    marker.setVisible(false);
                }
            }
        }
