Question

这是我正在使用的代码的核心，我没有得到错误，但我没有看到矩形区域中的点。任何帮助将不胜感激：

`enter code here`/** @this {google.maps.Rectangle} */
function showNewRect(event) {
 var ne = rectangle.getBounds().getNorthEast();
var sw = rectangle.getBounds().getSouthWest();
google.maps.event.addlistener(rectangle, "bounds_changed", function(){
  document.getElementById("map-selected").innerHTML=rectangle.getBounds();
  var rectA = (ne*sw);
 })


}

function listSelected（）{

var inside = $ .map（sites，function（s）{

  var d;

  if ( ( (d = google.maps.geometry.poly.containsLocation( s.position )) <= rectA  ) )
     return s.location + ' ('+(Math.round(d/100)/10)+' km)';
      $('#map-selected').html( inside.sort().join('') );

}）;

}


    google.maps.event.addListener(drawingManager, 'rectanglecomplete', function( rectangle )    {

   selectedArea = rectangle;
  listSelected();

  google.maps.event.addListener(rectangle, 'center_changed', listSelected);
  google.maps.event.addListener(rectangle, 'bounds_changed', listSelected);I am working with the Google maps API and I have a map I am drawing on with a rectangle. I need to have a user draw the rectangle, and on the map there will be predefined locations, that when the rectangle crosses the locations there will be details of each location put into a list.

这是一个例子：

我有一个使用圆形绘制工具的例子，我可以正常工作，但矩形工具我无法识别地图上的点。

如何在页面上没有预定义的矩形的情况下检查这些点？

谢谢，

当绘制Rectangle迭代位置并使用Rectangle的contains()方法bounds来测试LatLng是否在Rectangle的范围内

Google Maps API绘图矩形
