Do you mean 'feature' instead of 'feature class'? If so, the default editing widget for the javascript api handles deleting features. Here is a link to the Esri sample: http://help.arcgis.com/en/webapi/javascript/arcgis/jssamples/#sample/ed_default_editingwidget

I don't understand exactly what you're asking, but if you want to handle the delete manually and check whether a graphic is actually selected before trying to delete, you could do something like this:

var myFeatureLayer = new esri.layers.FeatureLayer("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Petroleum/KGS_OilGasFields_Kansas/MapServer/0",{
    mode: esri.layers.FeatureLayer.MODE_SELECTION,
    outFields: ["*"]

//get the selected graphic from the feature layer, only gets the first graphic, [0]
var targetGraphic = myFeatureLayer .getSelectedFeatures()[0];
//check if there is a selected graphic
if (targetGraphic) {
    //Delete subblock feature
    myFeatureLayer.applyEdits(null, null, [targetGraphic], function (adds, updates, deletes) {
        dojo.byId('infoPane').innerHTML = "Deleted feature successfully, OBJECTID: " + deletes[0].objectId;
    }, dojo.byId('infoPane').innerHTML = "Error when deleting feature");

Just a name for the feature layer-- you could call it myFeatureLayer. See edit above.. –  awesomo Feb 22 '13 at 20:49
