前言

对于SAP产品开发而言，功能需求的实现当之无愧，但是前端UI展示一直被吐槽，不够友好的界面，较为繁琐的操作流程，给用户增添了很多学习和使用上的烦恼。

但是自从SAPUI5诞生以来，移动显示，多元化的页面，不仅美观，更加实用便捷，下面我们来看看如何简单创建一个SAPUI5的应用。

首页创建

首先一个web应用程序，需要一个入口文件index.html:

<!DOCTYPE HTML>
<html>
    <head>
        <meta http-equiv='X-UA-Compatible' content='IE=edge'>
        <meta http-equiv='Content-Type' content='text/html;charset=UTF-8'/>

        <script src='resources/sap-ui-core.js'
                id='sap-ui-bootstrap'
                data-sap-ui-libs='sap.m'
                data-sap-ui-theme='sap_bluecrystal'>
        </script>
        <!-- only load the mobile lib 'sap.m' and the 'sap_bluecrystal' theme -->

        <script>
                sap.ui.localResources('helloworld');
                var app = new sap.m.App({initialPage:'idHelloWorld1'});
                var page = sap.ui.view({id:'idHelloWorld1', viewName:'helloworld.HelloWorld', type:sap.ui.core.mvc.ViewType.XML});
                app.addPage(page);
                app.placeAt('content');
        </script>

    </head>
    <body class='sapUiBody' role='application'>
        <div id='content'></div>
    </body>
</html>

编写View

view主要用于整体页面的布局展示，可以使用JS格式，XML格式，HTML格式，JSON格式，但是更为推荐大家使用XML格式语法。

<core:View xmlns:core='sap.ui.core' xmlns:mvc='sap.ui.core.mvc' xmlns='sap.m'
        controllerName='helloworld.HelloWorld' xmlns:html='http://www./1999/xhtml'>
    <Page title='Title'>
        <content>
            <Label text='This is Hello World'></Label>
        </content>
    </Page>
</core:View>

编写Controller

对于MVC结构而言自然少不了控制器，下面我们编写一个controller.

sap.ui.controller('helloworld.HelloWorld', {

/**
* Called when a controller is instantiated and its View controls (if available) are already created.
* Can be used to modify the View before it is displayed, to bind event handlers and do other one-time initialization.
* @memberOf helloworld.HelloWorld
*/
//  onInit: function() {
//
//  },

/**
* Similar to onAfterRendering, but this hook is invoked before the controller's View is re-rendered
* (NOT before the first rendering! onInit() is used for that one!).
* @memberOf helloworld.HelloWorld
*/
//  onBeforeRendering: function() {
//
//  },

/**
* Called when the View has been rendered (so its HTML is part of the document). Post-rendering manipulations of the HTML could be done here.
* This hook is the same one that SAPUI5 controls get after being rendered.
* @memberOf helloworld.HelloWorld
*/
//  onAfterRendering: function() {
//
//  },

/**
* Called when the Controller is destroyed. Use this one to free resources and finalize activities.
* @memberOf helloworld.HelloWorld
*/
//  onExit: function() {
//
//  }

});
