框架:SAPUI5 V.1.38.39IDE:WebIde
我在模型文件夹中创建了一个JSON文件Data.json,我想在我的控制器的onInit中使用创建JSON模型] >,我的实际问题是在Data.json上总是向我返回404响应。文件夹树它是初始的来自SAPUI5应用程序模板
test 1在webapp / controller / App.contoller.js中:
在webapp / controller / App.contoller.js中:onInit: function () { var oBusy = new sap.m.BusyDialog(); var oModel = new JSONModel(); oModel.attachRequestSent(function() { oBusy.open(); }); oModel.loadData("model/Data.json"); //here the path so I suppose here the problem oModel.attachRequestCompleted(function() { oBusy.close(); }); this.getView().setModel(oModel, "CompaniesModel") }
test 2
在webapp / controller / App.contoller.js中:onInit: function () { var oBusy = new sap.m.BusyDialog(); var oModel = new JSONModel(); oModel.attachRequestSent(function() { oBusy.open(); }); oModel.loadData("../model/Data.json"); //here the path so I suppose here the problem oModel.attachRequestCompleted(function() { oBusy.close(); }); this.getView().setModel(oModel, "CompaniesModel") }
test 3
onInit: function () { var oBusy = new sap.m.BusyDialog(); var oModel = new JSONModel(); oModel.attachRequestSent(function() { oBusy.open(); }); oModel.loadData("my/namespace/model/Data.json"); //here the path so I suppose here the problem oModel.attachRequestCompleted(function() { oBusy.close(); }); this.getView().setModel(oModel, "CompaniesModel") }
附录-复制过程:
在用于SAPUI5的Webide中,从模板SAPUI5应用程序选择SAP版本1.38.39中创建新的,初始化您的名称空间和视图/控制器名称。在模型中创建新的Data.json:
{ "Set1": [{ "Status": "status1", "Number": 10 }, { "Status": "status2", "Number": 20 }, { "Status": "status3", "Number": 30 }, { "Status": "status4", "Number": 40 }] }
您认为:
<mvc:View controllerName="your.namespace.controller.App" xmlns:l="sap.ui.layout" xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns:viz="sap.viz.ui5.controls" xmlns:viz.feeds="sap.viz.ui5.controls.common.feeds" xmlns:viz.data="sap.viz.ui5.data" xmlns:com="sap.suite.ui.commons" xmlns="sap.m"> <Shell id="shell"> <App id="app"> <pages> <Page id="page" title="{i18n>title}"> <content> <l:VerticalLayout class="sapUiContentPadding" width="100%"> <com:ChartContainer id="chartContainer" showFullScreen="true" showPersonalization="false" autoAdjustHeight="false" personalizationPress="attachPersonalizationPress" contentChange="attachContentChange" title="chart"> <com:content> <com:ChartContainerContent icon="sap-icon://line-chart" title="Line Chart"> <com:content> <viz:VizFrame id="idVizFrame_1" height='400px' width="100%" vizType='column' uiConfig="{applicationSet:'fiori'}"> <viz:dataset> <viz.data:FlattenedDataset data="{CompaniesModel>/Set1}"> <viz.data:dimensions> <viz.data:DimensionDefinition name="Status" value="{CompaniesModel>Status}"/> </viz.data:dimensions> <viz.data:measures> <viz.data:MeasureDefinition name="Number" value="{CompaniesModel>Orders}"/> </viz.data:measures> </viz.data:FlattenedDataset> </viz:dataset> <viz:feeds> <viz.feeds:FeedItem uid="valueAxis" type="Measure" values="Number"/> <viz.feeds:FeedItem uid="categoryAxis" type="Dimension" values="Status"/> </viz:feeds> </viz:VizFrame> </com:content> </com:ChartContainerContent> </com:content> </com:ChartContainer> </l:VerticalLayout> </content> </Page> </pages> </App> </Shell> </mvc:View>
在您的控制器中:
sap.ui.define([ "sap/ui/core/mvc/Controller", "sap/ui/model/json/JSONModel", ], function (Controller, JSONModel) { "use strict"; return Controller.extend("your.namespace.controller.App", { onInit: function () { //copy here one of the controller described in Problem in code & test } }); });
编辑(清单以外的其他选项):
如果您不想使用清单,我在这里添加了这种可能性,要使用清单,请转至@Cmdd的可接受答案:)如果您不想使用清单,可以执行:
oModel.loadData("../../../../../webapp/model/Data.json");
环境:框架:SAPUI5 V.1.38.39 IDE:WebIde要求:我在模型文件夹中创建了一个JSON文件Data.json,我想在控制器的onInit中使用它来创建一个...
最佳方法是将数据加载到manifest.json
中,如this链接中所述。
