Hello,
I see that you are looking for a piece of code that will trigger a pop up when a user from within the website tries to navigate out of the website
I am a web developer and have been developing websites for the past 4 years now.
I assure you that if you award me the project, I will complete it within the specified time meeting all your project requirements.
I invite you to further discuss your project with me.
Do consider my bid for this project.
I will be waiting for a reply.
Regards,
Morfsys
