Check webpage loaded or failed to load in WebView OS X 10.9

I need to check if the webpage loaded successfully or if there was any error while loading the webpage in WebView on OS X 10.9. How can I verify this? I can use the delegate method for the same on macOS 10.10 and higher using WKWebView(decidePolicyForNavigationResponse). Is there such a delegate method for WebView in OS X 10.9?
