我正在尝试完成示例 from Chapter 5 of the Leaflet.js succinctly book - 但无法在我的 map 上显示任何咖啡店。
有些命令会给我错误，所以我一直在寻找解决方法，我怀疑问题可能只是文件不在正确的位置这样简单。是否有我可以遵循的使用带有传单的数据库的白痴指南？或者有人可以看到我犯的错误吗？
我的设置:
- 在 Mac 上使用 XAMPP - MySQL 数据库和 Apache Web 服务器正在运行
- 我使用终端创建了 leafletDB 数据库
/Applications/xampp/xamppfiles/bin/mysql -u root -pcreate database leafletDB - 我通过将 CoffeeShops.sql 文件的内容复制粘贴到终端来填充数据库(我无法让来自 CSV 命令的
mysql –uroot –pleaflet < "C:\CoffeeShops.sql";工作，甚至更改 CoffeeShops.sql 的路径) - 使用
USE leafletDB;检查数据库SHOW TABLES;和SELECT COUNT(*) FROM coffeeshops;都给出了预期的结果。 - 传单数据库位于
/Applications/XAMPP/xamppfiles/var/mysql/ - 我将 coffee.php 文件复制到
/Applications/XAMPP/xamppfiles/htdocs/CoffeeExample文件夹，它与 listing43.html 文件(创建 map 的文件)是同一个文件 - 我对 listing43.html 文件所做的唯一更改是 mugIcon 的路径(放在同一文件夹中)。我还尝试简单地删除图标命令 - 它没有任何区别。
map 显示，任何直接编码到 html 文件中的标记显示 - 但数据库中没有任何内容。
我做错了什么？
这里是所有代码的副本 - 很抱歉这太长了
listing43.html

最佳答案
没错。
我尝试在 apache docker-container 中运行它，并在另一个 docker-container 中运行 mysql 数据库。关于可能的错误，我得到了一些建议。尽管我认为建议 2-4 最有可能帮助到您。
- 您用于导入 JQuery 的链接似乎已过时。而不是:
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.11.3.min.js"></script>
尝试:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
- 确保
coffee.php与数据库正确连接。您可以通过直接查看 PHP 输出 (http://localhost/coffee.php) 来完成此操作。coffee.php第 3 行的 sql 中的大写字母有问题。虽然 MySQL 在表名方面不区分大小写，但我相信 PHP 的$db->query();是。不管怎样，我都会远离大写的表名。 对我来说，我刚刚做了:
$sql = "SELECT * FROM coffeeshops WHERE City='Boston'";
我建议您检查的最后一件事是 JSON 编码和解码。
json_decode();，当输入格式不正确的 JSON 时，往往不会抛出错误。确保
getJSON函数实际返回正确的 JSON。我使用http://localhost/coffee.php作为 getJSON 请求的端点，而不仅仅是coffee.php。
如果这些都不能帮助您，请向我们提供 coffee.php 文件的返回输出以及数据的 console.log();由 getJSON 获取。
这是我得到的输出(我必须添加自己的 mug.png 文件): Screenshot of output on listing43.html
