如何更改 ng-map 标记的文本 'A' 和 'B'

Question

您好，我想更改 ng-map 的标记文本。它应该分别显示 "start" 和 "end" 而不是 "A" 和 "B"。

我确实提到了，但没有成功。它在标记上同时显示文本 "start" 和 "A"。

此外，如果您观察，源和目的地之间的距离与实际 google 地图显示的不同。

所以我在这里有三个问题。

1) 更改标记文本 "start" 而不是 "A"

2) 源和目的地之间的距离

3) 我想在点击按钮 "Draw Map" 时使用 AngularJS 显示这张地图。

下面是我的代码。

var mainModule = angular.module('mainApp',['ngRoute', 'ngMap']);
 mainModule.controller('mapCtrl', function($scope){
  $scope.sources = ["mumbai", "pune", "bangalore", "delhi", "netherlands"];
  $scope.destinations = ["pune", "bangalore", "mumbai", "delhi", "andorra"];
  $scope.origin = "mumbai";
  $scope.dest = "pune";
  $scope.drawMap = function(){
   var sourceVal = $('#sourceDdl').val();
   var destnVal = $("#destinationDdl").val();
   $scope.origin = sourceVal;
   $scope.dest = destnVal;
  }
  
 });

body {
    overflow: auto;
    background-color: #000000;
}

/* google map */
.ng-map-section{
 width: 800px;
    height: 600px;
    overflow: hidden;
    position: relative;
    background: #e6e6e6;
    border: 20px solid #FFF;
    margin-top: 20px;
}

Answer 1

for 1) 你可以只添加标签="X"

Answer 2

名称属性应为suppress-markers，因此将suppressmarkers='true'替换为suppress-markers="true"

更新示例

angular.module('mainApp', ['ngRoute', 'ngMap'])
    .controller('mapCtrl', function($scope) {
        $scope.sources = ["mumbai", "pune", "bangalore", "delhi", "netherlands"];
        $scope.destinations = ["pune", "bangalore", "mumbai", "delhi", "andorra"];
        $scope.origin = "mumbai";
        $scope.dest = "pune";
        $scope.drawMap = function() {
            var sourceVal = $('#sourceDdl').val();
            var destnVal = $("#destinationDdl").val();
            $scope.origin = sourceVal;
            $scope.dest = destnVal;
        }

    });

body {
    overflow: auto;
    background-color: #000000;
}
