You can drop nodeId param

+    {
+        InspectorTest.addResult(idValue + JSON.stringify(result, null, 2));
         callback();
     }
-    opt_frameId = opt_frameId || "";
-    InspectorTest.evaluateInPage("getInspectorHighlightJSON(\"" + nodeId + "\", \"" + opt_frameId + "\")", innerCallback);
 }
 
 };
