让您按（地区）或（城市）或任何类型进行筛选。我对此进行了测试，但它没有按预期工作。当您键入时，SearchBox会发出“自动完成”请求，但当您按enter键时，它会使用您输入的字符串在处发出请求。这可能返回也可能不返回实际结果。例如，通过键入“naxo”，自动完成列表将作为第一个结果返回“Naxos ke Mikres Kyklades”（可能这是基于区域设置的？）。按enter键，不选择列表项，返回0个结果。搜索框非常方便。我真的希望它能让我把搜索结果限制在地理编码或地址上。但搜索框和自动完成不同。更多的是像“纽约咖啡”这样的东西，我已经使用Autocomplete大约一年了，在阅读了这篇文章并切换到SearchBox之后，一切都好多了。我有一个特殊的“getPlaceFromAutocompleteList”函数作为解决方法，但它修复了几个令人沮丧的边缘案例错误。非常感谢。这在使用箭头键导航并按enter键选择的情况下不起作用。@dnlmzw如果使用箭头键导航并按enter键选择，则会触发“place_change”…@user151496这是真的，但如果您的字段是

字段则不起作用，那么您应该执行

e.preventDefault（）13/$.ui.keyCode.enter

keydown

，如果不按，请求的响应可能不会及时返回：）经过数小时的搜索和尝试破解类似的解决方案，这对我来说非常有效。这就像一个魅力。它需要jQuery。如果你和我一样在Angular上，这里有一个关于如何安装它的小指南：还要确保在

var autocomplete=new google.maps.places.autocomplete（输入）之前调用该函数否则它将不起作用。答案很好，代码格式糟糕。无论如何谢谢：）@Derenir已修复！我修改了上面的函数，它对我很有用listner使kepdown为true并选择此.searchElementRef.nativeElement.addEventListener（'keydown'，（e）=>{if（e.keyCode==13 | | e.keyCode==9）{var firstValue=$（'.pac container.pac item:first'）。text（）；//如果用户未使用箭头导航，且此操作尚未运行，则this.txtValue=firstValue；google.maps.event.trigger（e.target，'keydown'，{keyCode:40，hasRanOnce:true，}）；}）；
