应用机器学习数据
这个主要的AppML 的目的是提供数据到 HTML 页面。
将 AppML 连接到数据
- AppML可以显示来自变量的数据
- AppML可以显示文件中的数据
- AppML可以显示数据库中的数据
使用 JavaScript 对象的 AppML
分离 HTML 和数据的常见方法是将数据存储在 JavaScript 对象中。
示例
<table appml-data="
dataObj">
<tr>
<th>Customer</th>
<th>City</th>
<th>Country</th>
</tr>
<tr appml-repeat="records">
<td>{{CustomerName}}</td>
<td>{{City}}</td>
<td>{{Country}}</td>
</tr>
</table>
<script>
var dataObj = {
"records":[
{"CustomerName":"Alfreds Futterkiste","City":"Berlin","Country":"Germany"},
{"CustomerName":"Ana Trujillo Emparedados y helados","City":"México D.F.","Country":"Mexico"},
{"CustomerName":"Antonio Moreno Taquería","City":"México D.F.","Country":"Mexico"},
{"CustomerName":"Around the Horn","City":"London","Country":"UK"},
{"CustomerName":"B's Beverages","City":"London","Country":"UK"},
{"CustomerName":"Berglunds snabbköp","City":"Luleå","Country":"Sweden"},
{"CustomerName":"Blauer See Delikatessen","City":"Mannheim","Country":"Germany"},
{"CustomerName":"Blondel père et fils","City":"Strasbourg","Country":"France"},
{"CustomerName":"Bólido Comidas preparadas","City":"Madrid","Country":"Spain"},
{"CustomerName":"Bon app'","City":"Marseille","Country":"France"},
{"CustomerName":"Bottom-Dollar Marketse","City":"Tsawassen","Country":"Canada"},
{"CustomerName":"Cactus Comidas para llevar","City":"Buenos Aires","Country":"Argentina"},
{"CustomerName":"Centro comercial Moctezuma","City":"México D.F.","Country":"Mexico"},
{"CustomerName":"Chop-suey Chinese","City":"Bern","Country":"Switzerland"},
{"CustomerName":"Comércio Mineiro","City":"São Paulo","Country":"Brazil"}
]};
</script>

使用 JSON 文件的 AppML
分离 HTML 和数据的另一种常见方法是将数据存储在 JSON 文件中：
客户.js
{
"records":[
{"CustomerName":"Alfreds Futterkiste","City":"Berlin","Country":"Germany"},
{"CustomerName":"Ana Trujillo Emparedados y helados","City":"México D.F.","Country":"Mexico"},
{"CustomerName":"Antonio Moreno Taquería","City":"México D.F.","Country":"Mexico"},
{"CustomerName":"Around the Horn","City":"London","Country":"UK"},
{"CustomerName":"B's Beverages","City":"London","Country":"UK"},
{"CustomerName":"Berglunds snabbköp","City":"Luleå","Country":"Sweden"},
{"CustomerName":"Blauer See Delikatessen","City":"Mannheim","Country":"Germany"},
{"CustomerName":"Blondel père et fils","City":"Strasbourg","Country":"France"},
{"CustomerName":"Bólido Comidas preparadas","City":"Madrid","Country":"Spain"},
{"CustomerName":"Bon app'","City":"Marseille","Country":"France"},
{"CustomerName":"Bottom-Dollar Marketse","City":"Tsawassen","Country":"Canada"},
{"CustomerName":"Cactus Comidas para llevar","City":"Buenos Aires","Country":"Argentina"},
{"CustomerName":"Centro comercial Moctezuma","City":"México D.F.","Country":"Mexico"},
{"CustomerName":"Chop-suey Chinese","City":"Bern","Country":"Switzerland"},
{"CustomerName":"Comércio Mineiro","City":"São Paulo","Country":"Brazil"}
]
}
使用 AppML，您可以在 appml-data 属性中指定 JSON 文件作为数据源：
示例
<table
appml-data="customers.js">
<tr>
<th>Customer</th>
<th>City</th>
<th>Country</th>
</tr>
<tr appml-repeat="records">
<td>{{CustomerName}}</td>
<td>{{City}}</td>
<td>{{Country}}</td>
</tr>
</table>

使用数据库的 AppML
通过 Web 服务器的一点帮助，您可以为您的应用程序提供 SQL 数据。
此示例使用 PHP 从 MySQL 数据库读取数据：
示例
<table appml-data="
https://www.91xjr.com/appml/customers.html">
<tr>
<th>Customer</th>
<th>City</th>
<th>Country</th>
</tr>
<tr appml-repeat="records">
<td>{{CustomerName}}</td>
<td>{{City}}</td>
<td>{{Country}}</td>
</tr>
</table>
