我有一个网站：
input方法在$_GET字段中获取一些值。autofocus字段上获取input。我可以从数据库数据中建立的链接的方案是：
example.com?local=52.6762,19.7582 (i.e. lat, lng).
下面的代码仅在不使用URL内的点号的情况下才有效。因此，例如，如果我使用example.com?local=52,19，那么代码将按照我希望的那样工作。
但是通过example.com?local=52.6,19.7之类的链接，它似乎停止在步骤3上。
我认为该错误可能位于负责步骤4的代码的内部，即：
itemsloaded = google.maps.event.addDomListener(document.body, 'DOMNodeInserted', function(e) {
google.maps.event.trigger(input, 'keydown', {
keyCode: 13
})
});
也许您在项目中遇到了这个问题。请帮忙。

答案 0 :(得分：0)
这是您的代码的有效简化版本。
从地图idle事件中触发输入字段的焦点和按下键就足够了。无需设置超时等。
同样是AFAIK，在API URL中传递types=(cities)无效。
因此，如果我这样称呼此页面：map.php?local=52.6762,19.7582，则地图将以这些坐标为中心，并显示一个标记。
