Google maps 如何避免最终用户手动启动GooglePlaces自动完成下拉列表？

我正试图让google places autocomplete处理预定义的数据，但到目前为止运气不佳

假设我在一个预定义的输入字段中有一个文本“阿拉斯加南部，华盛顿州西雅图市”，如下所示：

<input id="ev-loc-input" size="60" value="Alaskan Way South, Seattle, WA" />

我不能使用这个，因为它会在地址查找完成后触发。我找不到可用的活动列表-也许有人知道

非常感谢任何帮助

我终于明白了！我已经做了两个小时了

无论如何，您需要关注您的输入元素，但您不能立即这样做。你需要推迟

所以，像这样

setTimeout(func, 2000);
function func() {
    input.focus();
    selectFirstResult();
}

这是我的代码，它是有效的

$(function() {
    var input = document.getElementById('searchTextField');
    input.value = "{{ $user["location"] }}";//I'm using laravel
    //You won't need the above line if you're already filling in the value of
    //the input field - I'm going to get this working without the map as well
    //I'll come back and post that later this weekend

                moveMarker(placeName, latlng);
                $("input").val(firstResult);
            }

     }
     function moveMarker(placeName, latlng){
        marker.setIcon(image);
        marker.setPosition(latlng);

使用这段代码会让我产生强烈的自责感。一定有更好的办法。悔恨的感觉？代码没有“错误”。从这篇帖子开始，我实际上已经深入研究了这一点，从whta我可以看出这确实是唯一的方法。我认为这与谷歌使用的延迟加载有关。他们会这样做，这样你的网站就不会坐等谷歌的回应了。所以，这很烦人，但我认为这实际上是一件好事的结果。@AlexandreBourlier您链接到的更干净的解决方案解决了另一个问题。
