Question

我一直在关注Google Maps API Places search box example，以便使用搜索框创建地图。

地图和搜索框都显示得很好。

问题是输入搜索框什么都不做。没有下拉列表，没有自动完成，按下回车不会启动搜索。

我错过了什么吗？

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的：

<script type='text/javascript'>
  var mapstyle = [{"featureType":"water","elementType":"geometry","stylers":[{"color":"#e9e9e9"},{"lightness":17}]},{"featureType":"landscape","elementType":"geometry","stylers":[{"color":"#f5f5f5"},{"lightness":20}]},{"featureType":"road.highway","elementType":"geometry.fill","stylers":[{"color":"#ffffff"},{"lightness":17}]},{"featureType":"road.highway","elementType":"geometry.stroke","stylers":[{"color":"#ffffff"},{"lightness":29},{"weight":0.2}]},{"featureType":"road.arterial","elementType":"geometry","stylers":[{"color":"#ffffff"},{"lightness":18}]},{"featureType":"road.local","elementType":"geometry","stylers":[{"color":"#ffffff"},{"lightness":16}]},{"featureType":"poi","elementType":"geometry","stylers":[{"color":"#f5f5f5"},{"lightness":21}]},{"featureType":"poi.park","elementType":"geometry","stylers":[{"color":"#dedede"},{"lightness":21}]},{"elementType":"labels.text.stroke","stylers":[{"visibility":"on"},{"color":"#ffffff"},{"lightness":16}]},{"elementType":"labels.text.fill","stylers":[{"saturation":36},{"color":"#333333"},{"lightness":40}]},{"elementType":"labels.icon","stylers":[{"visibility":"off"}]},{"featureType":"transit","elementType":"geometry","stylers":[{"color":"#f2f2f2"},{"lightness":19}]},{"featureType":"transit.station","elementType":"labels.icon","stylers":[{"visibility":"on"},{"hue":"#2185d0"},{"lightness":19}]},{"featureType":"administrative","elementType":"geometry.fill","stylers":[{"color":"#fefefe"},{"lightness":20}]},{"featureType":"administrative","elementType":"geometry.stroke","stylers":[{"color":"#fefefe"},{"lightness":17},{"weight":1.2}]}

    var markers = [];

    // Listen for the event fired when the user selects a prediction and retrieve
    // more details for that place.

        if (place.geometry.viewport) {

      map.fitBounds(bounds);

发现了这个问题。

其他地方有自动填充功能导致冲突：

<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>

Google Maps API地方搜索框无效
