AppML 数据
AppML 的 主要 目的是为 HTML 页面提供 数据。
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 和数据的常用方法是将数据存储在 JavaScript 对象中。
实例
<!DOCTYPE html>
<html>
<title>Customers</title>
<link rel="stylesheet" href="/example/appml/style.css">
<script src="https://cankaoshouce.com/js/appml/appml.js"></script>
<body>
<h2>Customers</h2>
<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>
</body>
</html>
使用 JSON 文件的 AppML
另一种分离 HTML 和数据的常用方法是将数据存储在 JSON 文件中:
customers.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,可以在 AppML 数据属性中指定 JSON 文件作为数据源:
实例
<!DOCTYPE html>
<html lang="en-US">
<title>Customers</title>
<link rel="stylesheet" href="/example/appml/style.css">
<script src="https://cankaoshouce.com/js/appml/appml.js"></script>
<body>
<h2>Customers</h2>
<div appml-data="/example/appml/customers.js">
<table>
<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>
</div>
</body>
</html>
使用数据库的 AppML
在 web 服务器的帮助下,您可以向应用程序提供SQL数据。
本例使用 ASPX 从 MySQL 数据库读取数据:
实例
<!DOCTYPE html>
<html>
<title>Customers</title>
<link rel="stylesheet" href="/example/appml/style.css">
<script src="https://cankaoshouce.com/js/appml/appml.js"></script>
<body>
<h2>Customers</h2>
<table appml-data="/example/appml/customers.ashx">
<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>
</body>
</html>
AppML 的强大功能
您即将发现 AppML 的强大功能。
AppML 可以为您提供以下数据、控制器和模型:
- 超简单的 HTML 应用程序开发
- 超级简单的建模、原型制作和测试
您可以在 HTML 页面中放入任意数量的 AppML 应用程序。
AppML 不会干扰页面的其他部分。
您可以完全自由地使用 HTML、CSS 和 JavaScript。
AppML 可以完全用于开发 CRUD web 应用程序。
CRUD: Create(创建), Read(读取), Update(更新), Delete(删除)。
