Answer 1

在SAP提供的

onSearch: function(oEvent) {
    //get the filter bar from the event
    var oFilterBar = oEvent.getSource();

    //get the filter items from the filter bar
    var aFilterGroupItems = oFilterBar.getFilterGroupItems();

    //map the array of FilterItems to a new array of sap.ui.model.Filter objects
    var aFilters = aFilterGroupItems.map(function(oFilterGroupItem) {

        //get the filter item name (which is now the same as the filter property name)
        var sFilterName = oFilterGroupItem.getGroupName();

        //use the filter bar to get the control for the filter
        var oControl = oFilterBar.determineControlByFilterItem(oFilterGroupItem);

        //use the control to get the selected value (selected key)
        var sSelectedValue = oControl.getSelectedKeys();                

        var oFilter = new sap.ui.model.Filter(sFilterName, "EQ", sSelectedValue);

        return oFilter;
   });

   this.getView().byId("table").getBinding("items").filter(aFilters);
}

文档中，提到如果要组合多个过滤器（AND或OR），则应创建一个新的Filter对象，其属性为Filterwhich，其中包含您要应用的已定义过滤器对象的数组。

根据该信息，您可以尝试在onSearch函数中添加以下代码（在关闭filters之后）：

.map()

并替换

var oFinalFilter = sap.ui.model.Filter({
    filters: aFilters, //aFilters = array of created Filter-objects
    and: true //true|false depending on requirements
});

通过

this.getView().byId("table").getBinding("items").filter(aFilters);
