HI All, I am facing issue where my graphic object is getting removed from map .I am using world map and adding feature layer in snap shot mode.I dont want to hit server again and again so hence i am keeping all featuer layer gaphics in dojo dictionary using below code dojo.forEach(featureLayer.graphics, function(graphic){
hashMap.add(graphic.attributes.CNTRY_NAME, graphic);
});
now when i want to highlight a country i do below .if (hashMap.containsKey(country)) {
var graphic = hashMap.item(country);
graphic.setSymbol(alertOfficeSymbol);
map.graphics.add(graphic);
}
I also have onClick functionality in my app.SO lets say onload of page i have to highlight somecountries lets India,USA,UK etc.now in some scenarios i have to clear these countries i.e i have to deHighlight them so i use below codeif (map.graphics != null) {
map.graphics.clear();
}
I have defined my onClick function as belowhandle=dojo.connect(map, "onClick", function(e){
selectCountries(e);
});
function selectCountries(e){
var graphic = evt.graphic;
var countryName = graphic.attributes.CNTRY_NAME;
}
Now when user clicks on India,USA,UK i get below error evt.graphic is undefinedso my graphic object is lost when i use map.graphics.clear();how to overcome this.
