Step 15: Nested Views

Step 15: Nested Views

嵌套view
当画面的控件变多后，最好不要只用一个view，分成多个view比较利于后面的维护和重用，所以就要使用的嵌套view

webapp/view/App.view.xml

<mvc:View
	controllerName="sap.ui.demo.walkthrough.controller.App"
	xmlns="sap.m"
	xmlns:mvc="sap.ui.core.mvc"
	displayBlock="true">
	<Shell>
		<App class="myAppDemoWT">
			<pages>
				<Page title="{i18n>homePageTitle}">
					<content>
						<mvc:XMLView viewName="sap.ui.demo.walkthrough.view.HelloPanel"/>
					</content>
				</Page>
			</pages>
		</App>
	</Shell>
</mvc:View>

把Panel里的内容，封装成一个view

webapp/view/HelloPanel.view.xml (New)

<mvc:View
   controllerName="sap.ui.demo.walkthrough.controller.HelloPanel"
   xmlns="sap.m"
   xmlns:mvc="sap.ui.core.mvc">
   <Panel
      headerText="{i18n>helloPanelTitle}"
      class="sapUiResponsiveMargin"
      width="auto" >
      <content>
         <Button
            text="{i18n>showHelloButtonText}"
            press=".onShowHello"
            class="myCustomButton"/>
         <Input
            value="{/recipient/name}"
            valueLiveUpdate="true"
            width="60%"/>
         <FormattedText
            htmlText="Hello {/recipient/name}"
            class="sapUiSmallMargin sapThemeHighlight-asColor myCustomText"/>
      </content>
   </Panel>
</mvc:View>

把原来App.view.xml里panel部分的内容移动到这里。并指定一个新的controller。

webapp/controller/HelloPanel.controller.js (New)

sap.ui.define([
   "sap/ui/core/mvc/Controller",
   "sap/m/MessageToast"
], function (Controller, MessageToast) {
   "use strict";
   return Controller.extend("sap.ui.demo.walkthrough.controller.HelloPanel", {
      onShowHello : function () {
         // read msg from i18n model
         var oBundle = this.getView().getModel("i18n").getResourceBundle();
         var sRecipient = this.getView().getModel().getProperty("/recipient/name");
         var sMsg = oBundle.getText("helloMsg", [sRecipient]);
         // show message
         MessageToast.show(sMsg);
      }
   });
});

把原来在App.controller.js里的按钮点击事件的代码移动到这里。

webapp/controller/App.controller.js

sap.ui.define([
   "sap/ui/core/mvc/Controller"
], function (Controller) {
   "use strict";
   return Controller.extend("sap.ui.demo.walkthrough.controller.App", {
   });
});

把原来在App.controller.js里的按钮点击事件的代码删除掉。
