drawingManager.setDrawingMode（null）导致递归太多 [英] drawingManager.setDrawingMode(null) causing too much recursion

问题描述

请查看这个小提琴， http://jsfiddle.net/HoffZ/Zu55b/

为什么它在 drawMan.setDrawingMode（null）

$ b上导致错误太多递归
$ b

  drawMan.setDrawingMode（google.maps.drawing.OverlayType.POLYGON）; 
 
 google.maps.event.addListener（drawMan，'overlaycomplete'，function（event）{
 //当绘图模式设置为null时，您可以编辑刚才绘制的多边形
 drawMan.setDrawingMode（null）; 
}）; 
  

这不是我的小提琴，但是我的代码中存在这个问题

解决方案

我必须承认，我不太明白为什么会发生这种情况。

下面的代码似乎工作：
$ b $ pre $ lt; code> google.maps.event.addListener（drawMan，'overlaycomplete'，function（event）{$ b）b
$ b if（drawMan.getDrawingMode（））{

drawMan.setDrawingMode（null）;
}
}）;

Please check out this fiddle, http://jsfiddle.net/HoffZ/Zu55b/

Why it is causing error "too much recursion" on drawMan.setDrawingMode(null)

drawMan.setDrawingMode(google.maps.drawing.OverlayType.POLYGON);

google.maps.event.addListener(drawMan, 'overlaycomplete', function (event) {
    // When draw mode is set to null you can edit the polygon you just drawed
    drawMan.setDrawingMode(null);
});

This is not my fiddle but I am having this exact issue in my code

解决方案

I must admit that I don't quite understand why this happens.

But the following code seems to work:

google.maps.event.addListener(drawMan, 'overlaycomplete', function (event) {

    if (drawMan.getDrawingMode()) {

        drawMan.setDrawingMode(null);
    }        
});
