Javascript 如何从Google Maps API中的拖动事件中获取自动完成地址？
我创建了一个谷歌地理编码器，我想能够拿起自动完成的地址标记时，被拖动或点击 这里的问题是，当搜索地址时，没有问题，它显示准确的位置，并提供自动完成的地址，如街道地址、城市、州、邮政编码、国家等 问题是，当将pin点从一个位置拖到另一个位置时，整个地址会根据google pin位置发生变化，但不会给出地址子部分，如街道地址、城市、州、邮政编码、国家（不更新意味着只有在那里才有旧的搜索值） 霉菌代码：Javascript 如何从Google Maps API中的拖动事件中获取自动完成地址？,javascript,jquery,html,google-maps,Javascript,Jquery,Html,Google Maps,我创建了一个谷歌地理编码器，我想能够拿起自动完成的地址标记时，被拖动或点击 这里的问题是，当搜索地址时，没有问题，它显示准确的位置，并提供自动完成的地址，如街道地址、城市、州、邮政编码、国家等 问题是，当将pin点从一个位置拖到另一个位置时，整个地址会根据google pin位置发生变化，但不会给出地址子部分，如街道地址、城市、州、邮政编码、国家（不更新意味着只有在那里才有旧的搜索值） 霉菌代码： <head> <title>Place Autocomplete Add
