在 sap fiori 应用程序中，搜索栏适用于模拟数据，而不适用于后端数据（sap ABAP（odata））

文件名：Master.Controller.js

 onSearch : function() {
            this.oInitialLoadFinishedDeferred = jQuery.Deferred();
            // Add search filter
            var filters = [];
            var searchString = this.getView().byId("searchField").getValue();
            if (searchString && searchString.length > 0) {
                filters = [ new sap.ui.model.Filter("QUARTER_ID", sap.ui.model.FilterOperator.Contains, searchString) ];
            }
            // Update list binding
            this.getView().byId("list").getBinding("items").filter(filters);

            //On phone devices, there is nothing to select from the list
            if (sap.ui.Device.system.phone) {
                return;
            }

            //Wait for the list to be reloaded
            this.waitForInitialListLoading(function () {
                //On the empty hash select the first item
                this.selectFirstItem();
            });
        },

文件名：Master.view.xml

您必须弄清楚来自后端的数据是否与模拟数据相同。如果没有，绑定可能出错了。请检查数据是否最初与所有后端数据一起加载到列表中。之后，尝试进行搜索。在函数中放置一个断点onSearch，查看数据是否仍然存在以及如何创建过滤器。
