appML的主要目的是提供数据的HTML页面。
连接appML到数据
- appML可以显示来自变量的数据
- appML可以显示从文件中的数据
- appML可以显示从数据库中的数据
appML使用JavaScript对象
分离HTML和数据的常用方法，是将数据存储在JavaScript对象。
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":"Mexico D.F.","Country":"Mexico"},
{"CustomerName":"antonio Moreno Taqueria","City":"Mexico D.F.","Country":"Mexico"},
{"CustomerName":"around the Horn","City":"London","Country":"UK"},
{"CustomerName":"B's
Beverages","City":"London","Country":"UK"},
{"CustomerName":"Berglunds
snabbkop","City":"Lulea","Country":"Sweden"},
{"CustomerName":"Blauer See
Delikatessen","City":"Mannheim","Country":"Germany"},
{"CustomerName":"Blondel
pere et fils","City":"Strasbourg","Country":"France"},
{"CustomerName":"Bolido
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":"Mexico D.F.","Country":"Mexico"},
{"CustomerName":"Chop-suey Chinese","City":"Bern","Country":"Switzerland"},
{"CustomerName":"Comercio Mineiro","City":"Sao Paulo","Country":"Brazil"}
]};
</script>
试一试» appML使用JSON文件
分离HTML和数据另一种常见的方法是将数据存储在一个JSON文件：
customers.js
{
"records":[
{"CustomerName":"alfreds Futterkiste","City":"Berlin","Country":"Germany"},
{"CustomerName":"ana Trujillo Emparedados y helados","City":"Mexico D.F.","Country":"Mexico"},
{"CustomerName":"antonio Moreno Taqueria","City":"Mexico D.F.","Country":"Mexico"},
{"CustomerName":"around the Horn","City":"London","Country":"UK"},
{"CustomerName":"B's Beverages","City":"London","Country":"UK"},
{"CustomerName":"Berglunds
snabbkop","City":"Lulea","Country":"Sweden"},
{"CustomerName":"Blauer See
Delikatessen","City":"Mannheim","Country":"Germany"},
{"CustomerName":"Blondel
pere et fils","City":"Strasbourg","Country":"France"},
{"CustomerName":"Bolido
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":"Mexico D.F.","Country":"Mexico"},
{"CustomerName":"Chop-suey Chinese","City":"Bern","Country":"Switzerland"},
{"CustomerName":"Comercio Mineiro","City":"Sao Paulo","Country":"Brazil"}
]
}随着appML，你可以指定一个JSON文件作为数据源appml-data属性：
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>
试一试» appML使用数据库
从Web服务器的帮助不大，你可以喂与SQL数据应用程序。
本例中使用PHP来从一个MySQL数据库中读取数据：
例
<table appml-data=" http://www.w3ii.com/appml/customers.php" >
<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> 试一试» 此示例使用.NET从一个SQL Server数据库中读取数据：
例
<table appml-data=" http://www.w3ii.com/appml/customers.aspx" >
<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> 试一试» appML的力量
