我正在使用gmap4rails绘制一些相当复杂的多边形作为区域边界。我有两件事情需要帮助：
首先，我想将点击时的信息窗口与这些多边形相关联。这是我用例的一个例子： https：// google -developers.appspot/maps/documentation/javascript/examples/polygon-arrays
我试过在gmap的回调中注册一个click事件处理函数但它不起作用，我不认为这是正确的方法。
Gmaps.map.callback = function（） { console.log（'sup ）; var infowindow = new google.maps.InfoWindow （{ content：'you clicked me！'， suppressMapPan：true }）; google.maps.event.addListener（Gmaps.map.polygons [0]，'click'，function（） { console.log（click event fired）; infowindow.open（map，Gmaps.map.polygons [0]）; }）; }其次，我希望能够更改在某些用户事件上通过jQuery填充这些多边形的颜色（例如，用户点击复选框）。
解决方案将您的方法替换为：
Gmaps.map.callback = function（） { console.log（'sup）; Gmaps.map.polygons [0] .infowindow = new google.maps.InfoWindow （{ content：'you clicked me！'}）; google.maps.event.addListener（Gmaps.map.polygons [0] .serviceObject，'click'，function（event） { console.log（the点击事件触发）; infowindow = Gmaps.map.polygons [0] .infowindow; infowindow.setPosition（event.latLng）; infowindow.open（Gmaps.map.map） ; }）;然后更改这个gem的js行换成真实的而不是假的。由于我不喜欢光标更改，因此我设置为false。无论如何，它应该在配置选项。请在github上创建一个问题，以便我记得修复它。
I'm using gmap4rails to draw a bunch of fairly complicated polygons that serve as district boundaries. I've got two things i would like help with:
Firstly, I want to associate an info window on click with these polygons. This is an example of my use-case: google-developers.appspot/maps/documentation/javascript/examples/polygon-arrays
I've tried registering a click event handler in the gmap's callback but it doesn't work and I don't think it's the right approach.
Gmaps.map.callback = function() { console.log("'sup"); var infowindow = new google.maps.InfoWindow ({ content: 'you clicked me!', suppressMapPan:true }); google.maps.event.addListener(Gmaps.map.polygons[0], 'click', function() { console.log("the click event fired"); infowindow.open(map, Gmaps.map.polygons[0]); }); }Secondly, I'd like to be able to change the fill-color of these polygons via jquery on some user-events (user clicks a checkbox for example). How would I go about that using the gem?
解决方案Replace your method with:
Gmaps.map.callback = function() { console.log("'sup"); Gmaps.map.polygons[0].infowindow = new google.maps.InfoWindow ({ content: 'you clicked me!' }); google.maps.event.addListener(Gmaps.map.polygons[0].serviceObject, 'click', function(event) { console.log("the click event fired"); infowindow = Gmaps.map.polygons[0].infowindow; infowindow.setPosition(event.latLng); infowindow.open(Gmaps.map.map); }); }And change this gem's js line to put true instead of false. I did set to false since I didn't like the cursor change. Anyway it should be in configuration options. Please create an issue on github so that I remember to fix it.
