How to zoom to features

Question

Hi guys,

I´m developing an application that uses the time slider and I need to zoom to features that correspond to the selected time extent.  I don't know if time slider returns an array of features or graphics so i can use it for setting the map extent or something like that.

Thanks for your help.

In the Feature Layer class there are some methods you can use to query the data, check out the selectFeatures method as well as esri.layers.FeatureLayer.MODE_SELECTION.
dojo.connect(yourTimeSlider, "onTimeExtentChange", function(timeExtent) {
   yourFeatureLayer.selectFeatures(query, esri.layers.FeatureLayer.SELECTION_NEW, function (features) {
       // do something with the features here
   });
});

You could zoom to the selected features, or graphics by using this: esri.graphicsExtent(graphics)
