How can I check the marker is or isn't in the bounds using google maps v3

google-maps, google-maps-api-3, javascript

Solution

The `LatLngBounds` object comes with a `contains()` method which takes a `LatLng` point and returns true if the point happens to be within the bounds, or false if outside.

Therefore, what about something like the following?

function check_is_in_or_out(marker){
  return map.getBounds().contains(marker.getPosition());
}

Problem

This is my code, I think it may has some mistakes: ``` var bounds_array; google.maps.event.addListener(map,'bounds_changed', function (){ var bounds_=map.getBounds(); if(bounds_){ var leftBottom=[bounds_.getSouthWest().lat(),bounds_.getSouthWest().lng()] var rightTop=[bounds_.getNorthEast().lat(),bounds_.getNorthEast().lng()] bounds_array=[leftBottom,rightTop]; } }); function check_is_in_or_out(marker){ var leftBottom=bounds_array[0],rightTop=bounds_array[1]; var marker_p=[marker.getPosition().lat(),marker.getPosition().lng()]; if(marker_p[0]<leftBottom[0]||marker_p[0]>rightTop[0]|| marker_p[1]<leftBottom[1]||marker_p[1]>rightTop[1])return 0;//0 is out else return 1;//1 is in } ``` Is this code enough to check the bounds is in or out?
