Two outputs at a time with button click

Question

I have made a three fields form using html code. Name, email & phone number. And i created Login button. I linked that login button to go to external webpage. What I need is at the same time when user clicks Login button, the filled fields name, email & number should be received through mail to me. And also that Login button takes user to another webpage. How to do this simply ? How to get mail with filled fields & also how to redirect user to another webpage just by clicking Login button. With single action clicking Login button, i should receive mail of filled details & user should go to next webpage. What's the exact script i should write ?? Where to insert the script exactly ??

You should use JS for this. But you need API or other tool for backend process.
