Add a second filter without deleting the existing ones
Hi I have a search box with this code behind it:
onSearch : function (oEvent) {
if (oEvent.getParameters().refreshButtonPressed) {
// Search field 'refresh' button has been pressed.
// This is visible if you select any master list item.
// In this case no new search is triggered, we only
// refresh the list binding.
this.onRefresh();
} else {
var andFilter = [];
var sQuery = oEvent.getParameter("query");
if (sQuery && sQuery.length > 0) {
// add filters
var oTableSearchState = [];
oTableSearchState = [new Filter("Supplier", FilterOperator.Contains, sQuery), new Filter("BusArea", FilterOperator.Contains, sQuery), new Filter("CostCenter", FilterOperator.Contains, sQuery),
new Filter("FuncArea", FilterOperator.Contains, sQuery)];
andFilter.push(new Filter(oTableSearchState, false));
}
this._applySearch(andFilter);
}
},
And a filter button that should add additional filters. Something like that:
onSetFilter : function(oEvent) {
var andFilter = [];
andFilter.push(new Filter("BusArea", FilterOperator.EQ, "5000"));
this._applySearch(andFilter);
},
But of course the "BusArea" part should depend on which filters are selected. There can be more than one filter. The _applySearch function looks like this:
_applySearch: function(andFilter) {
var oViewModel = this.getModel("worklistView");
this._oTable.getBinding("items").filter(andFilter, true);
// changes the noDataText of the list in case there are no filter results
if (andFilter.length !== 0) {
oViewModel.setProperty("/tableNoDataText",
this.getResourceBundle().getText("worklistNoDataWithSearchText"));
}
}
the problem is that when I add a filter via the filter button, the filters from the search bar disappear and the other is arround. how can i modify my code so that i can add filters without removing existing ones?

After our chat, I made this snippet using the global model.

The ComboBox and Button mimics your dialog. Login mimics SearchField
Both are bound to global "filtersModel" and both call the _calculateFilters () function when submitting information
