Get a google places autocomplete status

Question

如何在谷歌地方获取状态自动完成搜索..如果我在谷歌中键入一些东西自动完成文本框，如果地方不存在那么如何发出警告该地方无效？

I think you can use something like this.

var displaySuggestions = function(predictions, status) {
  if (status != google.maps.places.PlacesServiceStatus.OK) {
    alert(status);
    return;
  }
