javascript - 带有参数(托管图像的 URL)的 Ng map 标记图标不起作用

Question

在 ng map 中，这是有效的:

<marker ng-repeat="helper in helpers" position="{{helper.position}}" optimized="false" icon={{helper.facebook.freshURL}}"></marker>

但是如果我在“icon”中输入参数:

<marker ng-repeat="helper in helpers" position="{{helper.position}}" optimized="false" icon="{url: '{{helper.facebook.freshURL}}', anchor: [0,0]}"></marker>

该网址似乎在网址前面有一个前缀“localhost:8000”，并且出现错误:

GET http://localhost:8100/%7Burl:%20https://graph.facebook.com/1716361775351742/picture?type=normal,%20anchor:%20[0,0]} 404 (Not Found)

这是我这边的错误还是语法错误？谢谢。

Answer 1

此行为与解析表达式时发生的 JSON 错误有关:{url: '{{helper.facebook.freshURL}}',anchor: [0,0]}

为 icon 属性提供有效表达式后，例如 icon='{"url":"{{helper.facebook.freshURL}} ","anchor":[0,0]}'，标记图标将被正确初始化。

示例

var app = angular.module('appMaps', ['ngMap']);
app.controller('mapCtrl', function ($scope) {
    
    $scope.cities = [
       { id: 1, name : "Brisbane", location: [-33.867396, 151.206854] }
    ];


    $scope.iconProperties = {
       url : "http://maps.google.com/mapfiles/marker.png",
       anchor: [0,0]   
    };

    $scope.iconUrl = "http://maps.google.com/mapfiles/marker.png";

});
