How to enable catch Javascript error in a page via .net.

[Xun He]

I am using .net PhantomJS lib(namespace OpenQA.Selenium.PhantomJS) to implement a project trying to catch all the script error within a page. I couldn't find a way to enable onError described in this page:

http://phantomjs.org/api/phantom/handler/on-error.html

There is no option in PhantomJSDriverService class, neither a PhantomJS command line option. How can I enable this in .net?

My code snippet:

            PhantomJSDriverService service = PhantomJSDriverService.CreateDefaultService(myPhantomJSPath);

            PhantomJSDriver) webDriver = new PhantomJSDriver(service);

//onError.js contains the code in http://phantomjs.org/api/phantom/handler/on-error.html to enable catching error.

            string script = File.ReadAllText("onError.js");

            var result = webDriver.ExecutePhantomJS(script);

            EventFiringWebDriver driver = new EventFiringWebDriver(webDriver);

            driver.ExceptionThrown += myExceptionHandler;

It will throw script error exception on a call to execute script directly on my code, like this:

            Driver.ExecuteScript("var y=window.prompt(\"Test script with error\");window.alert(z);");

but won't throw similar script error exception on a page which contains similar error, script portion of my page looks like:

<script>

var y=1;alert(mm);

</script> 

Does anyone know how to make this work on throwing error on script error on a page?

Thanks,
