javascript - 我如何使用 MarkerWithLabel 中的 labelContent 访问值，它们之间有空间

Question

当我从谷歌地图 API 中的 json 数据访问值并在 MarkerWithLabel、labelContent:building.Post-completion 的帮助下添加标记时。但是当我运行此代码时，它显示，ReferenceError: 完成未定义，但我的 json 数据具有以下类型。我认为 Post-completion 中的 - 字符存在问题，它无法读取单个句子。但有一个与之关联的值。

  var activity_status = [{"Completion": 0, "Pipeline": 0,  "Implementation": 5, "country": "MYANMAR", "Post-completion": 138, "Cancelled": 0},
                       {"Completion": 0, "Pipeline": 0, "Implementation": 0, "country": "Bahrain", "Post-completion": 0, "Cancelled": 0},
                      {"Completion": 0, "Pipeline": 0, "Implementation": 0, "country": "ZIMBABWE", "Post-completion": 1, "Cancelled": 0},
                      {"Completion": 0, "Pipeline": 0, "Implementation": 12, "country": "MONGOLIA", "Post-completion": 34, "Cancelled": 0},{}];






 for(var j= 0; j < activity_status.length; j++) {
        (function(i) {
         var building = activity_status[i];

        geocoder.geocode({'address':building.country}, function(results,status){

          if(status == google.maps.GeocoderStatus.OK){
            var marker = new MarkerWithLabel({
              position:new google.maps.LatLng(results[0].geometry.location.lat(),results[0].geometry.location.lng()),
              title:building.country,

              map:map,
              labelContent:building.Post-completion, 
              labelAnchor:new google.maps.Point(6,22),
              labelClass:"labels",
              labelInBackground:false,
              icon:"circle2.png"
            });
             console.log(building.country)
          }
          else{
                 console.log("Geocode was not  succcessful for the following reason:" + status);
             }
        });
       })(j);

像访问数组一样访问它。 建筑['竣工后']
