How to pass inputs from one function to another using .apply method?

Question

For my assignment, I have to read 3 inputs. Once I have the input, I have to pass them as arguments to the addNewPost function. I understand that I have to use the .apply function, however, I am confused on how to do this even after looking at various sources online.

function handleFormSubmit() {



    var username = document.getElementById("input-username").value,

        password = document.getElementById("input-password").value,

        picture = document.getElementById("input-picture").value;



    addNewPost.apply(this, arguments);

}



function addNewPost(username, img_src, caption) {



}

Am I correctly reading the inputs, and if I am, how do I pass them as arguments to addNewPost?

If using apply is not a requirement, you can simply pass them into the function;

addNewPost(username, password, picture);
