问题:

I have a JSON model like this:

{     "VEHICLES": [         {             "vehicleId": "0001",             "routeName": "Ginza Line"         },         {             "vehicleId": "0002"             "routeName": "Another Line"         } }

I am implementing a sort function like this:

onSearch : function (oEvent) {     var sQuery = oEvent.getParameter("query");      if (sQuery) {         var oFilter1 = new Filter("vehicleId", function(value) {             return value.includes("sQuery");         });          var oFilter2 = new Filter("routeName", function(value) {             return value.includes("sQuery");         });          var allFilter = new Filter([oFilter1, oFilter2], false});         var list = this.getView().byId("masterList");         list.getBinding("items").filter(allFilter);     }  }

When I input "000" in search field, I am expecting to return both data items, but it returns none. Why?

I have tried single "vehicleId" filter, it worked.

I have also tried

var allFilter = new Filter({     filters: [oFilter1, oFilter2],      and: false  //OR });

But allFilter.bAnd returned undefined, I am confused.

There is a small mistake. You are checking if the vehicleId includes the string "sQuery". Remove the quotes around sQuery and the filters will work fine.

value.includes(sQuery);

Thanks to @boghyon and @suryabhan mourya, I changed the fnTest function to

var oFilter1 = new Filter("vehicleId", function(value) {     return value.includes(sQuery.toUpperCase()); });

and it's working!

Update:

according to API document. Put the parameter to Array

list.getBinding("items").filter([allFilter]);

@boghyon found from the source code here that it is actually got converted to Array
