JavaScript谷歌地图绘画事件 [英] Javascript google maps drawing events

问题描述

我在google maps api提供的事件侦听器中遇到问题。事情是，有些事件运行，有些不是。我有一个setListeners函数，用于在多边形叠加完成后设置侦听器。我想要挂钩的事件是：set_at，insert_at，remove_at并单击。现在，点击事件正确运行，但其他人没有。我能做什么错？这里是代码：

  self.setListeners = function（）{
 //这个点击事件正确运行
 google.maps.event.addListener（self.map，'click'，function（e）{
 self.clearSelection（）; 
}）
 
 console.log （self.drost）; 
 if（typeof self.drost！='undefined'）{
 self.drost.addListener（'set_at'，function（e）{
 console.log（e.overlay）; 
}）; 
 self.drost.addListener（'insert_at'，function（e）{
 console.log（e.overlay）; 
}）; 
 self.drost.addListener（'remove_at'，function（e）{
 console.log（e.overlay）; 
}）; 
 //此点击也正确运行
 self.drost.addListener（'click'，function（e）{
 self.setSelection（self.drost）; 
}）$ 
 
 
 
 
 $ b $ p 
 $ p 
事件 set_at ， insert_at ， remove_at 需要添加到多边形的路径中，而不是多边形本身。

I'm having a problem with the event listeners provided by google maps api. The thing is, that some events run, some not. I have a setListeners function which sets the listeners after the polygon overlay is complete. The events I would like to hook are: set_at, insert_at, remove_at and click. Now the click events run correctly, but the others not. What could I do wrong? Here is the code:
self.setListeners = function () {
        //this click event runs correctly
        google.maps.event.addListener(self.map, 'click', function (e) {
            self.clearSelection();
        })

        console.log(self.drost);
        if (typeof self.drost != 'undefined') {
            self.drost.addListener('set_at', function (e) {
                console.log(e.overlay);
            });
            self.drost.addListener('insert_at', function (e) {
                console.log(e.overlay);
            });
            self.drost.addListener('remove_at', function (e) {
                console.log(e.overlay);
            });
            //this click also runs correctly
            self.drost.addListener('click', function(e){
                self.setSelection(self.drost);
            })
        }
}
Thanks in advance!
解决方案
The events set_at, insert_at, remove_at need to be added to the path of the polygon, not the polygon itself.
