javascript - How to use Leaflet GeoJson Options -


i'm trying implement choropleth of nyc leaflet. i'm following along on it's tutorial doing so, , going fine until reached "adding interaction" section. when try add mouseover function, or other, can't e defined, , chrome console throws uncaught typeerror: cannot read property 'setstyle' of undefined error.

this way i've been adding highlightfeature option oneachfeature

l.geojson(geojsonzipcode, {style: style, oneachfeature: highlightfeature}).addto(map);

these 2 functions being called, style works fine, highlightfeature not:

function style(feature) {   return {     fillcolor: getcolor(feature.properties.density),     weight: 1,     opacity: 1,     color: 'white',     dasharray: '3',     fillopacity: 0.7   }; }  function highlightfeature(e) {   var layer = e.target;    layer.setstyle({     weight: 5,     color: '#666',     dasharray: '',     fillopacity: 0.7   });    if (!l.browser.ie && !l.browser.opera) {     layer.bringtofront();   } }

under 'adding interaction' section of tutorial you're following, highlightfeature attached listener hover events: separate oneachfeature function this. follow technique in tutorial closely , you'll avoid issue.
