在加载中心Google地图InfoWindow [英] Center Google Maps InfoWindow On Load

问题描述

我在加载页面时遇到了一个将InfoWindow居中的问题。在加载时，地图以标记为中心，将InfoWindow关闭屏幕（我正在使用地图容器的高度很小）。

I'm having a problem centering my InfoWindow on page load. On load, the map is centering on the marker, which puts the InfoWindow off screen (I'm working with a short height for my map container).

现在单击marker会将InfoWindow中的地图重新居中，以使其看起来完全像我想要的。既然如此，我甚至试着开启marker.click触发器来实现负载解决方案，但没有运气。我缺少什么？

Now clicking the marker does re-center the map on the InfoWindow so that it looks exactly like I want. That being the case, I've even tried firing the marker.click trigger to achieve a solution on load, but had no luck. What am I missing?

推荐答案

您显然只需要等待更长的时间才能触发点击事件。

You apparently just need to wait longer before triggering the click event.

// wait until the map is idle.
google.maps.event.addListenerOnce(map, 'idle', function() {
  setTimeout(function() {
    // wait some more (...)
    google.maps.event.trigger(marker, 'click'); //still doesn't work
  },2000);
});
