点击听众冲突与infowindow

标签: google-maps-api-3 infowindow

我正在尝试创建一个允许用户报告线索的地图 通过在infowindow中单击并填写表单来解决问题(类似于 seeclickfix.com)。我还没有内置实际的php / SQL 保存用户提供的信息。 问题:我的infowindow的html中有一个按钮供用户使用 提交信息并关闭窗口。而不只是关闭 虽然窗口,我的新标记的事件监听器会收到点击 通过infowindow,在按钮后面创建一个不需要的标记。 谷歌以某种方式避免了这个问题;他们没有注册点击 右上角'x'。 我试图创建一个布尔信号变量('infopen')来让 我的addMarker函数知道infowindow是否打开,但事实并非如此 功能....任何想法为什么?

有关代码的任何其他建议将不胜感激! (我的任务是创建一个组织和存储多个系统 信息窗口/标记...)

答案 0 :(得分:0)

我的设计黑客:在infowindow.close()周围添加一个setTimeout()。有一个理由,如下所述。

function saveData() {
   setTimeout(function() { infowindow.close(); }, 100);
}

//closes window and clears marker
function cancel() {
   setTimeout(function() { infowindow.close(); marker.setMap(null); }, 100);
}

100毫秒似乎合理。奇怪的是,在cancel()中将标记设置为空映射也必须超时。我认为你不再需要infopen了。

我从这个代码示例中得到了这个想法: http://code.google.com/apis/maps/articles/phpsqlinfo_v3.html

在此示例中,infoWindow仅在发出数据库请求后关闭(在回调中)并确保响应良好。当然,这必须花费几毫秒。因此,根据这些假设,一旦你的数据库部分工作,你可以替换丑陋的setTimeout,一切都应该工作! :)
