Google 地图 API 地点搜索框不起作用

Question

我一直在关注 Google Maps API Places search box example 以创建带有搜索框的地图。

地图和搜索框都显示得很好。

问题是在搜索框中输入没有任何反应。没有下拉菜单，没有自动完成，按回车键也不会启动搜索。

我是不是漏掉了什么？

HTML:

<script src='//maps.google.com/maps/api/js?v=3.13&amp;sensor=false&amp;libraries=geometr‌y,places' type='text/javascript'></script>

<input id='pac-input' class='controls' type='text' placeholder='Search'>

<div id='map_search' style='width: 100%; height: 30rem;'>

JavaScript:

找到问题。

其他地方的自动完成功能导致了冲突：

<script type='text/javascript'>
  function initialize() {
    var input = document.getElementById('search_address');

    var autocomplete = new google.maps.places.Autocomplete(input);
  }

  google.maps.event.addDomListener(window, 'load', initialize);
</script>

<script type='text/javascript'>
  function initialize() {
    var input = document.getElementById('listing_address');

    var autocomplete = new google.maps.places.Autocomplete(input);
  }

  google.maps.event.addDomListener(window, 'load', initialize);
</script>
