拖动地图时，Google地图会加载其他标记

Question

I've created a Google Map where markers are loaded via Json. 我创建了一个Google地图，其中通过Json加载了标记。 I have been doing a lot of research to load additional markers when the map is dragged, but the function onClickCallback does not get fired. 我一直在做很多研究，以在拖动地图时加载其他标记，但是不会触发onClickCallback函数。 Would you please help me? 你能帮我吗？

Answer 1

I think if you changed it from 'dragend' to 'idle' it would serve two purposes. 我认为，如果将其从'dragend'更改为'idle'则有两个目的。 It would run the search for thumbnails after a zoom event and a pan event. 它将在缩放事件和平移事件之后运行缩略图搜索。

bounds are updated for both pan and zoom? 平移和缩放的边界是否已更新？
