Question

我想在gmaps上创建多个矩形，但我不知道在哪里放置代码。

这是我的示例代码

 function initMap() {
    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 5,
      center: {lat: 37.0924, lng: -119.4179324},
      mapTypeId: 'terrain'
    });

	var contentString = '<div id="content">'+
        '<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large 
        '</div>';
		
	  var infowindow = new google.maps.InfoWindow({
      content: contentString
    });

    var rectangle = new google.maps.Rectangle({
      strokeColor: '#FF0000',
      strokeOpacity: 0.8,
      strokeWeight: 2,
      fillColor: '#FF0000',
      fillOpacity: 0.35,
      map: map,
      bounds: 
      new google.maps.LatLngBounds
  <?php 
	  $con = mysqli_connect("localhost","root","","test");
	  
	  $query=mysqli_query($con,"SELECT * FROM map");
	  $cc=mysqli_fetch_array($query);
	  ?>
      (
        new google.maps.LatLng (<?php echo $cc['nelat']; ?>, <?php echo $cc['nelng']; ?>),
		new google.maps.LatLng (<?php echo $cc['swlat']; ?>, <?php echo $cc['swlng']; ?>),
        ),

      
    });
	  rectangle.addListener('click', function() {
      infowindow.open(map, rectangle);
    });
  }

    #map {
        height: 100%;
      }
      html, body {
        height: 100%;
        margin: 0;
        padding: 0;
      }

在该片段中仅显示1个矩形。如果我想添加其他矩形，我必须把代码放在哪里？示例我想在不同的位置显示5个矩形。并为每个矩形提供信息窗口

添加一个单独的矩形变量：

function initMap() {
        var map = new google.maps.Map(document.getElementById('map'), {
          zoom: 5,
          center: {lat: 37.0924, lng: -119.4179324},
          mapTypeId: 'terrain'
        });

        var rectangle = new google.maps.Rectangle({
          strokeColor: '#FF0000',
          strokeOpacity: 0.8,
          strokeWeight: 2,
          fillColor: '#FF0000',
          fillOpacity: 0.35,
          map: map,
          bounds: 
          new google.maps.LatLngBounds

          (
            new google.maps.LatLng (37.778261, -119.4179324),new google.maps.LatLng (36.255123, -115.2383485),
            ),

          
        });
        var rectangle2 = new google.maps.Rectangle({
          strokeColor: '#FF0000',
          strokeOpacity: 0.8,
          strokeWeight: 2,
          fillColor: '#FF0000',
          fillOpacity: 0.35,
          map: map,
          bounds: 
          new google.maps.LatLngBounds

          (
            new google.maps.LatLng (30.778261, -119.4179324),new google.maps.LatLng (29.255123, -115.2383485),
            ),

          
        });
      }

    #map {
        height: 100%;
      }
      html, body {
        height: 100%;
        margin: 0;
        padding: 0;
      }
