我有一张带有几个标记的(谷歌)地图。这些标记的坐标和描述存储在对象中,标记在循环中创建。现在,我想为每个标记添加一个click事件,并将“key”值作为链接目标。这是我的代码片段:
对象:
$localstorage.setObject('lsStations', {
"STA": {lat: '50.93358', lng: '6.57', name: 'Station A'},
"STB": {lat: '50.9332', lng: '6.56690', name: 'Station B'},
"STC": {lat: '50.934', lng: '6.566', name: 'Station C'}
});
创建地图和标记:
.controller('GMapsCtrl', function ($scope, $localstorage) {
'use strict';
// initialize variables
var map,
myLatLng = new google.maps.LatLng(50.93358, 6.56692),
stationCoords = $localstorage.getObject('lsStations');
$scope.init = function () {
var mapOptions = {
zoom: 16,
// default center
center: myLatLng,
// disable google maps ui
disableDefaultUI: 1
},
map = new google.maps.Map(document.getElementById('map'), mapOptions),
marker = [],
index,
key;
for (key in stationCoords) {
if (stationCoords.hasOwnProperty(key)) {
// add marker for station
marker[key] = new google.maps.Marker({
position: new google.maps.LatLng(stationCoords[key].lat, stationCoords[key].lng),
map: map,
title: stationCoords[key].name
});
// add click event for each marker
google.maps.event.addListener(marker[key], 'click', function () {
$scope.startStation = key;
alert(key);
}
)}
}
};
$scope.init();
});
当我点击任何标记时,警报文本为“STC”而不是“STA”表示第一个,“STB”表示第二个,“STC”表示第三个标记。因此我尝试将函数代码放在循环之外:
.controller('GMapsCtrl', function ($scope, $localstorage) {
'use strict';
// initialize variables
var map,
myLatLng = new google.maps.LatLng(50.93358, 6.56692),
stationCoords = $localstorage.getObject('lsStations');
$scope.init = function () {
var mapOptions = {
zoom: 16,
// default center
center: myLatLng,
// disable google maps ui
disableDefaultUI: 1
},
map = new google.maps.Map(document.getElementById('map'), mapOptions),
marker = [],
index,
key;
function createMarker() {
$scope.startStation = key;
alert(key);
//window.location.href = '#/station/' + key;
}
for (key in stationCoords) {
if (stationCoords.hasOwnProperty(key)) {
// add marker for station
marker[key] = new google.maps.Marker({
position: new google.maps.LatLng(stationCoords[key].lat, stationCoords[key].lng),
map: map,
title: stationCoords[key].name
});
// add click event for each marker
google.maps.event.addListener(marker[key], 'click', createMarker(key));
}
}
};
$scope.init();
});
使用此代码,警报对话框获得正确的文本(“STA”,“STB”和“STC”)。但是当页面加载时它们都会被触发,如果我点击标记就没有任何反应。
如何为每个标记分配一个点击事件,并为每个标记指定不同的键值?
谢谢!

你可以使用一个闭包(这是基于发布建议然后将其删除的人的想法)
createMarkersForRecommendations = function() {
return stationCoords.forEach(function(rec, idx) {
var thisPoint;
thisPoint = new google.maps.LatLng(rec.lat, rec.lng);
map.markers[idx] = new google.maps.Marker({
title: rec.rname,
position: thisPoint,
icon: rec.icon,
});
map.markers[idx].setMap(map);
google.maps.event.addListener(map.markers[idx], "click", (function(ix) {
if (Restos.debug) {
console.log(ix + 1, map.markers[ix].getTitle());
}
return $scope.$apply(); // as a google maps click event does not trigger an angluar digest
}).bind(null, idx));
});
};

我稍微更改了Aqib Mapari的代码片段,现在它正在运行:
google.maps.event.addListener(marker[key], 'click', function () {
var thisMarker;
for (thisMarker in marker) {
if (marker[thisMarker] === this) {
// link to detail page for selected marker
window.location.href = '#/station/' + thisMarker;
}
}
});

实际上我认为可能有一种更简单的方法 - 我认为你已经有了封闭,但是没有正确使用它
function createMarker(key) {
// ^^^
$scope.startStation = key;
alert(key);
//window.location.href = '#/station/' + key;
}

尝试在点击功能中进行此更改。它对我有用。
google.maps.event.addListener(marker[key], 'click', function () {
for(var j=0; j<marker.length; j++){
if(marker[j] == this){
$scope.startStation = key;
alert(key);
}
}
});

感谢。
