这是我目前的code时的界限，改变了被称为和作品：

This is my current code which is called when bounds are changed and works:

 scope.boundsChanged= function(arg){
       console.log(arg);                       
 };

基本上，我需要lat和液化天然气的新阵列时上面这个函数被调用。我不确定是检索。

I basically need the new array of lat and lng when this function above is called. I'm unsure are the retrieve it.

我在一家指令采用了棱角分明的版本1使用JavaScript使用templateUrl。

I'm using angular version 1 with JavaScript in a directive using a templateUrl.

我不知道究竟是什么在boundsChanged（）函数返回，但假设改变的界限，在函数返回的，方法是相同的获得纬度，经度坐标：

I dont know exactly what is returned in the boundsChanged() function, but assuming changed bounds are returned in the function, method is the same to get lat, lng coordinates:

scope.boundsChanged= function(arg){

    //assuming changed bounds is returned as the 'arg'
    var polygonBounds = arg;
    var coordinates = [];

    for (var i = 0; i < polygonBounds.length; i++)
    {
        coordinates.push({lat: polygonBounds.getAt(i).lat(), lng: polygonBounds.getAt(i).lng()});
        coordinates.push(new google.maps.LatLng(polygonBounds.getAt(i).lat(), polygonBounds.getAt(i).lng()));
    }

   console.log(arg);                       
};
