如何检查谷歌地图是否已满载? [英] How can I check whether Google Maps is fully loaded?

问题描述

我正在将 Google 地图嵌入到我的网站中.加载 Google 地图后，我需要启动一些 JavaScript 进程.

I’m embedding Google Maps into my web site. Once Google Maps is loaded, I need to kick off a few JavaScript processes.

有没有办法自动检测 Google 地图何时完全加载，包括图块下载等?

存在一个 tilesloaded() 方法，它应该完全完成这个任务，但是 它不起作用.>

A tilesloaded() method exists that is supposed to accomplish exactly this task but it does not work.

推荐答案

这让 GMaps v3 困扰了我一段时间.

This was bothering me for a while with GMaps v3.

我找到了一种方法来做到这一点:

I found a way to do it like this:

google.maps.event.addListenerOnce(map, 'idle', function(){
    // do something only the first time the map is loaded
});

当地图进入空闲状态时触发空闲"事件 - 一切都已加载(或加载失败).我发现它比 tileloaded/bounds_changed 更可靠，并且使用 addListenerOnce 方法，闭包中的代码在第一次触发空闲"然后分离事件时执行.

The "idle" event is triggered when the map goes to idle state - everything loaded (or failed to load). I found it to be more reliable then tilesloaded/bounds_changed and using addListenerOnce method the code in the closure is executed the first time "idle" is fired and then the event is detached.

另请参阅 Google 中的事件部分地图参考.
