This sample demonstrates how to filter features by attributes on the client-side. This can be done by creating a new FeatureFilter and specifying its where clause then applying the filter object to the layer view's filter property.

How it works

The sample filters flash flood warnings by the season they are issued in. To see the flash flood warnings issued in different seasons, click on the filter button, then select a season.

// User clicked on Winter, Spring, Summer or Fall
// set an attribute filter on flood warnings layer view
// to display the warnings issued in that season
function filterBySeason(event) {
  const selectedSeason ="data-season");
    floodLayerView.filter = {
      where: "Season = '" + selectedSeason + "'"
