Retrieve attributes of a feature when clicked

YohanBienvenue — Tue, 22 May 2012 19:43:02 GMT

Hi,

Here is a screenshot of my map, where a feature in the map is clicked and an InfoTemplate is displaying the attributes for that feature.

[ATTACH=CONFIG]14527[/ATTACH]

What I want to do is when I click one of the buttons in my InfoTemplate, I want to save the attributes of the feature I just clicked moments before. How do I know what feature I just clicked?

One idea I had was maybe assign a click handler for the layer graphics, but since the features are obtained from a REST map service (which is an asynchronous request) I cannot figure out when to make this assignment since I don't know exactly when the graphics have all been added to the map.

Thanks

There are probably a bunch of ways you could approach this - here is one suggested method:

dojo.connect(featureLayer, "onClick", function(evt) {   console.log(evt.graphic.attributes); });

Yes this method will work for what I want to do..
And I don't know how I missed this in the API documentation. I remember seeing the setAttributes method and thinking "why isn't there a getAttributes too? That would be useful". Somehow I missed it in the properties..
I blame influenza

Thanks Steve 🙂
