gmaps4rails 2.4.6未捕获引用错误:未定义Gmaps

gmaps4rails 2.4.6 unCaught Reference Error: Gmaps not defined

本文关键字：错误 引用 未定义 Gmaps gmaps4rails      更新时间：2023-09-26

我花了几个小时阅读StackOverflow上的解决方案，并尝试了所有方法，但仍然没有找到解决方案。

我得到

未捕获参考错误：Gmaps未定义

来自

handler = Gmaps.build('Google');

我已经多次重新安排我的脚本标签，试图解决这个问题。它们现在位于我的'application.html.erb'布局中，看起来像这样：

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <!-- Always force latest IE rendering engine (even in intranet) & Chrome Frame
  Remove this if you use the .htaccess -->
  <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
  <title>NomadSpaces</title>
  <meta name="description" content="">
  <meta name="author" content="Christopher Dodd">
  <meta name="viewport" content="width=device-width; initial-scale=1.0">
  <!-- Replace favicon.ico & apple-touch-icon.png in the root of your domain and delete these references -->
  <%= favicon_link_tag '/favicon.ico' %>
  <link rel="apple-touch-icon" href="/apple-touch-icon.png">
  <%= stylesheet_link_tag('application', :media => 'all') %>
  <%= stylesheet_link_tag('spaces', :media => 'all') %>
  <%= javascript_include_tag 'application', "data-turbolinks-track" => true %>
  <%= yield :javascripts %> // Code that calls Gmaps
  <%= javascript_include_tag 'gmaps_api.js' %>
  <%= javascript_include_tag 'markerclusterer_packed.js' %>

</head>
<body>
<%= yield %>
</body>
</html>

我的application.js文件如下：

    // This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
// WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD

//
//= require jquery
//= require jquery.ui.all
//= require jquery_ujs

//= require gmaps/google

详细的违规功能：

handler.buildMap({
            internal: {id: 'sidebar_builder'},
            provider: {
                zoom: 15,
                center:    new google.maps.LatLng(53.385873, -1.471471),
                mapTypeId: google.maps.MapTypeId.ROADMAP,
                styles:    mapStyle
            }
        }, function(){
            var json_array = <%=raw @hash.to_json %>;
            var markers = handler.addMarkers(json_array);
            _.each(json_array, function(json, index){
                json.marker = markers[index];
            });
            createSidebar(json_array);
            handler.bounds.extendWith(markers);
            handler.fitMapToBounds();
        });

地图应显示的空间：

<div class="row">
    <div id="map-area">
      <div id="sidebar_builder" class="visible"></div>
      <div class="ball"></div>
      <p class="loading">LOADING SPACES</p>
    </div>
    <div id='sidebar_container'></div>
  </div>

请帮忙！

我让一个朋友查看了我的项目，发现错误的原因是application.js没有编译，因此gmaps javascript没有加载到页面上。

有了这些知识，我们回到Stack Overflow，并尝试更改ruby版本来解决这个问题。不幸的是，这并没有奏效。

为了解决这个问题，我启动了一个新的rails项目，并从旧项目中复制了重要的代码。我的application.js文件现在已正确加载，一切都恢复正常。
