javascript - 在php中正确显示 map infoWindow

Question

如何循环关联数组的值？现在我一次只能参加一个协会!在这里，我将 MySQL 表中的所有值传递给 json_encode，仅将纬度和经度作为数组的数组以及其他字符串。谢谢

function myMap() {

  var infowindow = new google.maps.InfoWindow();

  var mapOptions = {
      zoom: 5,
      center: new google.maps.LatLng(44.849716, 10.052282),
      mapTypeId: 'roadmap',
      styles: []
  };

  var i = 0;
  var mapElement = document.getElementById('map');
  var map = new google.maps.Map(mapElement, mapOptions);
  var markers = <?= json_encode($this->getCoordinatesMaps[0]); ?>; //Passing the PHP values to JS


  var marker, i;
  //Add marker to map
  for(var i in markers) {
      var marker = markers[i];
      var marker = new google.maps.Marker({
          position: new google.maps.LatLng(marker.lat, marker.long),
          map: map,
          title: 'Niente',
          clickable: true
      });


      google.maps.event.addListener(marker, 'click', (function(marker, i) {
                    return function() {
                        infowindow.setContent(<?= json_encode($this->getCoordinatesMaps[0]->comune); ?> + ' - ' + <?= json_encode($this->getCoordinatesMaps[0]->mansione_tecnica); ?>);
                        infowindow.open(map, marker);
                    }
                })(marker, i));
      }
  }

setContent 方法需要一个字符串。您正在传递多个参数

infowindow.setContent(markers[i].lat,markers[i].long);

正确的做法应该是:infowindow.setContent('这里是我的内容');
