Hello.
I'm using Selenium WebDriver and Firefox, with the HAR Export Trigger add-on. I'm trying to use Seleniums execute_script function to return the value/data from the HAR test page, but I don't know JS at all, and I'm not a Perl expert. Basically, I don't know how to do a callback in the JS.I started out as simple as possible. I'm using the HAR Content API Test Page (http://janodvarko.cz/har/tests/har-export-trigger/har-export-api.html). I can do a simple call to get the title of the page, that's not what I'm after though.
I think the best way is to just post the code below and it'll hopefully illustrate more clearly what I'm trying to accomplish. I commented out some profile settings to try and conform to the HAR test page recommendations.
I've included some inline comments in the code explaining script_1, script_2, script_3 JS strings.
Any assistance greatly appreciated. Thanks for your time.
