Dynamically changing fillColor variables in leaflet

One way of dynamically styling vector layer would be to have some global variable and then use it within style function to select desired style. Upon global variable change, .setStyle vector layer method has to be used to update style.

This could look then something like this:

var selectedPropertyNo = 0;

function style(feature) {
  var fillColor;
  if (selectedPropertyNo == 1)
    fillColor = getDensityColor(feature.properties.density);
  else {
    fillColor = getIncomeColor(feature.properties.income);
  }
  return {
    weight: 2,
    opacity: 1,
    color: 'white',
    dashArray: '3',
    fillOpacity: 0.7,
    fillColor: fillColor
  };
}

function changeLayerStyle(propertyNo) {
  selectedPropertyNo = propertyNo;
  vectorLayer.setStyle(style);
}
