UI5-技术篇-Hybrid App-2-Geolocation位置定位

在SAP WEB IDE简单测试基于HTML5自带的定位功能，相关步骤如下：

1.VIEW代码

 1 <mvc:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m"
 2     controllerName="zrico_appnszrico_pn_scan.controller.GeoLocation" xmlns:html="http://www.w3.org/1999/xhtml">
 3     <App>
 4         <pages>
 5             <Page             
 6             title="{i18n>GeoLocation.Page.title}" 
 7             showNavButton="true" 
 8             navButtonPress="onNavBack" 
 9             backgroundDesign="Transparent">
10                 <content>
11                     <Button id="BTGeoLoc" text="{i18n>GeoLocation.Button.text}" type="Emphasized" press="onGeoLocButton" > </Button>
12                 </content>
13             </Page>
14         </pages>
15     </App>
16 </mvc:View>

2.Controller代码

 1 jQuery.sap.includeScript("/webapp/src/src/cordova.js");
 2 sap.ui.define([
 3     "zrico_appnszrico_pn_scan/controller/BaseController",
 4     "sap/ui/core/mvc/Controller",
 5     "sap/ui/core/UIComponent",
 6     "sap/m/MessageBox",
 7     "sap/ui/Device"
 8 ], function(BaseController,Controller,UIComponent,MessageBox,Device) {
 9     "use strict";
10 
11     return BaseController.extend("zrico_appnszrico_pn_scan.controller.GeoLocation", {
12         
13         onGeoLocButton: function () {
14             //document.addEventListener("deviceready", this.onDeviceReady, false);
15             navigator.geolocation.getCurrentPosition(this.onSuccess2, this.onError2, { maximumAge: 3000, timeout: 30000})  //精度设置 enableHighAccuracy: true 
16         },
17         
18         onSuccess2:function(position){
19               MessageBox.show(
20                   "Latitude: "          + position.coords.latitude          + "
" +
21                   "Longitude:"          + position.coords.longitude         + "
" +
22                   "Altitude: "          + position.coords.altitude          + "
" +
23                   "Accuracy: "          + position.coords.accuracy          + "
" +
24                   "Altitude Accuracy: " + position.coords.altitudeAccuracy  + "
" +
25                   "Heading:  "          + position.coords.heading           + "
" +
26                   "Speed:     "          + position.coords.speed             + "
" +
27                   "Timestamp:"          + position.timestamp                + "
");
28          },
29         
30         onError2:function(error){
31              MessageBox.show(
32                  "code: "    + error.code    + "
" +
33                 "message: " + error.message + "
");
34          }
35 
36     });
37 
38 });

3.SAP WEB IDE 测试

　chrome谷歌浏览器执行过程中报错，应该是网络原因需要翻墙。

　在IE浏览器中测试，显示正常。
