Inject JS issue

thanks @aksh1yadav , its working now.


I have an issue with Inject JS myself.
I dragged the activity inside an Open Browser and added “alert(‘test’)” in the ScriptCode field. The error thrown is “TypeError: Object expected”.
I tried indicating a random element in the page and also leaving the Selector field empty - none worked.

Can anyone advise how to inject javascript code directly without using a js file?

Hi @aksh1yadav ,

It seems to be working in Chrome but not IE. Will investigate the security settings.

Thanks a lot!

I have tried with your example…It is working fine with chrome browser but not with IE. Is there any setting that need to be changed in IE…?


CHrome browser some selectors will very so :slight_smile:
