我已经开发了一个项目,其中包含valuehelp函数,使用Odata而不是JSON,在显示表时出现错误,而不显示数据列和行。
选择一行后,它显示所有行值,但不显示项目值。
我的控制器代码:
onInit:函数(){ this.getRouter()。attachRoutePatternMatched(this.onRouteMatched,this); //值帮助 this._oMultiInput = this.getView()。byId(" multiInput"); this._oMultiInput.setTokens(this._getDefaultTokens()); this._oMultiInput.addValidator(this._onMultiInputValidate); this.oColModel =新的JSONModel(sap.ui.require.toUrl(" myNamespace")+"/columnsModel.json"); var oHelpModell = new sap.ui.model.json.JSONModel(); var oModell = new sap.ui.model.odata.v2.ODataModel(" http://MYSERVICENAME/"); oHelpModell.loadData(oModell,true); oHelpModell.setData() /* var DataLoaded = oModell.read("/img/MYENTITYNAME", {成功:功能(响应){ //响应将重新执行请求 console.log(response.results); MessageToast.show("成功"); },错误:function(e){ MessageToast.show("失败");} }); */ var oDataLoad = oModell.setProperty("/img/MYENTITYNAME"); this.getView()。setModel(oDataLoad); }, onValueHelpRequested:function(){ var aCols = this.oColModel.getData()。cols; this._oBasicSearchField = new SearchField({ showSearchButton:否 }); this._oValueHelpDialog = sap.ui.xmlfragment(" myNamespace.fragment.ValueHelpDialogInputSuggestions",this); this.getView()。addDependent(this._oValueHelpDialog); this._oValueHelpDialog.setRangeKeyFields([{ 标签:"材料编号", 密钥:"材料编号", 类型:"字符串", typeInstance:new typeString({},{ 最大长度:7 }) }]); this._oValueHelpDialog.getFilterBar()。setBasicSearch(this._oBasicSearchField); this._oValueHelpDialog.getTableAsync()。then(function(oTable){ oTable.setModel(this.oDataLoad); oTable.setModel(this.oColModel," columns"); if(oTable.bindRows){ oTable.bindAggregation(" rows","/img/MYENTITYNAME"); } 如果(oTable.bindItems){ oTable.bindAggregation(" items","/img/MYENTITYNAME",函数(){ 返回新的ColumnListItem({ 单元格:aCols.map(function(column){ 返回新的Label({text:" {" + column.template +"}"}); }) }); }); } this._oValueHelpDialog.update(); } .bind(this)); this._oValueHelpDialog.setTokens(this._oMultiInput.getTokens()); this._oValueHelpDialog.open(); }, onValueHelpOkPress:函数(oEvent){ var aTokens = oEvent.getParameter(" tokens"); this._oMultiInput.setTokens(aTokens); this._oValueHelpDialog.close(); }, onValueHelpCancelPress:函数(){ this._oValueHelpDialog.close(); }, onValueHelpAfterClose:function(){ this._oValueHelpDialog.destroy(); }, onFilterBarSearch:函数(oEvent){ var sSearchQuery = this._oBasicSearchField.getValue(), aSelectionSet = oEvent.getParameter(" selectionSet"); var aFilters = aSelectionSet.reduce(function(aResult,oControl){ 如果(oControl.getValue()){ aResult.push(new Filter({ 路径:oControl.getName(), 运算子:FilterOperator。包含, value1:oControl.getValue() })); } 返回结果; },[]); aFilters.push(new Filter({ 过滤器:[ 新的Filter({路径:" Matnr",运算符:FilterOperator。包含,值1:sSearchQuery}), 新的Filter({路径:" Maktx",运算符:FilterOperator。包含,值1:sSearchQuery}) ], 和:false })); this._filterTable(new Filter({ 过滤器:aFilters, 和:正确 })); }, _filterTable:函数(oFilter){ var oValueHelpDialog = this._oValueHelpDialog; oValueHelpDialog.getTableAsync()。then(function(oTable){ 如果(oTable.bindRows){ oTable.getBinding(" rows")。filter(oFilter); } 如果(oTable.bindItems){ oTable.getBinding(" items")。filter(oFilter); } oValueHelpDialog.update(); }); }, _onMultiInputValidate:function(oArgs){ 如果(oArgs.suggestionObject){ var oObject = oArgs.suggestionObject.getBindingContext()。getObject(), oToken = new Token(); oToken.setKey(oObject.ProductId); oToken.setText(oObject.Name +"(" + oObject.ProductId +")"); } 返回null; }, _getDefaultTokens:function(){ var ValueHelpRangeOperation = compLibrary.valuehelpdialog.ValueHelpRangeOperation; var oToken1 = new Token({ 键:" 100-100", 文字:" hjjggjhggj" }); var oToken2 =新令牌({ 键:" range_0", 文字:" 100-100" })。数据范围", { "排除":是的, " operation":ValueHelpRangeOperation.EQ, " keyField":"材料ID", " value1":" 100023", " value2":"材料成本" }); 返回[oToken1,oToken2]; },

Myjson.json { " cols":[ { " label":"材料编号", " template":" Matnr" }, { " label":"描述", " template":" Maktx" } ] }
任何人都可以帮助我解决此错误
谢谢。

通过为JSON文件提供正确的路径来解决错误。
