Question

我正在使用ngMap显示带有标记的地图。我想在用户点击标记时将用户重定向到网址。要构建此URL，我需要一个唯一的id，来自repeat。

我有这个;

<marker ng-repeat="position in ctrl.positions" position="{{position.x}}, {{position.y}}" on-click="ctrl.goto(ctrl.id)"></marker>

在我的控制器中我有

vm.clickRedirect = function(pId) {
    console.log(pId);
}

我只返回对象和实际的id（ctrl.id）。我如何实现这个目标？

Answer 1

通过on-click事件替换clickRedirect函数将对象标识符作为参数传递给：

vm.clickRedirect = function(event,pId) {
    console.log(pId); 
}

工作示例

angular.module('mapApp', ['ngMap'])
    .controller('mapCtrl', function ($scope, NgMap) {


        NgMap.getMap().then(function (map) {
            $scope.map = map;
        });
        $scope.cities = [
            { id: 1, name: 'Oslo', pos: [59.923043, 10.752839] },
            { id: 2, name: 'Stockholm', pos: [59.339025, 18.065818] },
            { id: 3, name: 'Copenhagen', pos: [55.675507, 12.574227] },
            { id: 4, name: 'Berlin', pos: [52.521248, 13.399038] },
            { id: 5, name: 'Paris', pos: [48.856127, 2.346525] }
        ];

        $scope.showInfo = function (event,id) {
              $scope.selectedCity = $scope.cities.filter(function(c){
                  return c.id === id;  
              })[0]; 
        };
    });

            <marker ng-repeat="c in cities" position="{{c.pos}}" title="{{c.name}}" id="{{c.id}}" on-click="showInfo(c.id)">
            </marker>
        </ng-map>
</div>

Answer 2

on-click不是角度表达式您需要使用角度表达式来评估ctrl.id
像这样：{{ctrl.id}}
或者您的意思是使用ng-click？

ngMap中的点击标记是否为id？
