如何获取修改后的绘图管理器形状的点坐标?谷歌地图 API v3

本文介绍了如何获取修改后的绘图管理器形状的点坐标?谷歌地图 API v3的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有这个 DrawingManager 对象:

I have this DrawingManager Object:

    drawingManager = new google.maps.drawing.DrawingManager({
      drawingMode: google.maps.drawing.OverlayType.POLYGON,
      markerOptions: {
        draggable: true
      },
      polylineOptions: {
        editable: true
      },
      polygonOptions: polyOptions,
      map: map
    });

当一个多边形完成时，我得到他们的坐标:

And when a Polygon is completed I get their coords with:

    google.maps.event.addListener(drawingManager, 'polygoncomplete', function (polygon) {
        var coordinates = (polygon.getPath().getArray());
        console.log(coordinates);
      });

但是，如果我使用 DrawingManager 更改多边形，显然形状会改变，可能会添加更多点..
那么如何在修改后获取所有点及其坐标，例如单击按钮以完成编辑??提前致谢.

But if I change the polygon using DrawingManager obviously the shape will change, maybe adding more Points..
Then How can I get all Points with their coords after modify it and for example click a button to finish the edition?? Thanks in advance.

推荐答案

好的，我的第二个代码有了答案:

Ok having the answer on my second code:

var coordinates = (polygon.getPath().getArray());

最后，我通过添加一个监听器来调用获取数组的函数，从而得到了最后一个带有坐标的数组:

Finally I got the last array with coordinates calling this code by adding a listener to call a function that get the array:

function getCoordinates() {
    console.log(polygon.getPath().getArray());
}

google.maps.event.addDomListener(document.getElementById('CoordsButton'), 'click', getCoordinates);

HTML

<button id="CoordsButton">Coordinates</button>

然后当现在点击按钮时，我得到了坐标...

Then when the button is clicked now I get the coords...

还是谢谢
