您好我想更改 ng-map 的标记文本。它应该分别显示“开始”和“结束”而不是“A”和“B”。
我确实提到了这个，但没有运气。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谷歌地图显示的距离不同。
所以我在这里有三个问题。
1）更改标记文本“开始”而不是“A”
2) 源与目的地之间的距离
3）我想使用AngularJS点击“绘制地图”按钮来显示这张地图。
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;
