How to stop the posting process in a client side script
I wrote a small client-side script, which checks
on a regular expression, and if it contains certain words, displays a recommendation to the user to avoid them.
The script is activated by clicking on the post button of the post / topic.
The question is is it possible to stop the publication of the post along with the presentation of the recommendation (I present the recommendation via app.alert)? Let there be a recommendation, and the post not be published? I want something on the client side, not a server side extension
