Web编程学习八：通过Apache Cordova将Web应用移动化

2014-04-02 12:29 435 查看

上一个练习，做了一个简单但是完整的Web应用，使用HTML5技术实现的。

今天做个更加有趣的小练习，现在我再通过Apache Cordova来将其封装为iOS上的移动应用。

我们可以看到基本上不需要做任何修改就可以迁移到iOS平台上了。

Cordova就是以前的PhoneGap。

主页地址：https://cordova.apache.org/

1.安装Cordova

我这里安装的cordova 3.0.6

2.创建一个项目Apache Cordova 项目，名称叫employee

cordova -d create ~/Documents/CordovaProjects/employee com.sample employee

增加对iOS的支持：

cordova -d platform add ios

3.下载sapui5的包，解压缩后将resource文件夹拷贝到employee/www下

4.修改一下index.html

<script src="resources/sap-ui-core.js" id="sap-ui-bootstrap"
data-sap-ui-libs="sap.ui.commons, sap.ui.table"
data-sap-ui-theme="sap_bluecrystal">

</script>

<script>
// create the DataTable control
var oTable = new sap.ui.table.Table({
editable : true
});

// define the Table columns
var oControl = new sap.ui.commons.TextView({
text : "{Id}"
}); // short binding notation
oTable.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : "ID"
}),
template : oControl,
sortProperty : "id",
filterProperty : "id",
width : "100px"
}));

// define the Table columns
var oControl = new sap.ui.commons.TextView({
text : "{FirstName}"
}); // short binding notation
oTable.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : "First Name"
}),
template : oControl,
sortProperty : "firstName",
filterProperty : "firstName",
width : "100px"
}));

// define the Table columns
var oControl = new sap.ui.commons.TextView({
text : "{LastName}"
}); // short binding notation
oTable.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : "Last Name"
}),
template : oControl,
sortProperty : "lastName",
filterProperty : "lastName",
width : "100px"
}));

var oModel = new sap.ui.model.odata.ODataModel(
"http://localhost:8080/jpa2/Employee.svc/");

//var oModel = new sap.ui.model.odata.ODataModel(serviceUrl);

oTable.setModel(oModel);
oTable.bindRows("/Employees");

// finally place the Table into the UI
oTable.placeAt("content");
</script>

<script type="text/javascript" src="cordova.js"></script>

<title>Hello World</title>
</head>

<body class="sapUiBody" role="application">
<div id="content"></div>
</body>

</html>

5.拷贝文件到项目中去：

cordova -d prepare ios

6.用XCode打开employee项目，在iOS模拟器上运行：

小结：这就是使用HTML5来开发的好处了，我们可以非常方便地通过Cordova将web应用迁移到各个不同的手机平台上。
