The above codes explain for only front end

let us now talk how codes in javasceript, this will explain how we can preview an ID.
Students Full Name:
Stuedents Year of Studies:
Students Date of Birth:
Students ID Number:

Below are the codes for javascript

const preview = document.getElementById("preview");
preview.addEventListener("click", prev);

function prev(){
const inName = document.getElementById("inName").value;
const inBirth = document.getElementById("inBirth").value;
const inField = document.getElementById("inField").value;
const inYear= document.getElementById("inYear").value;
const inNum= document.getElementById("inNum").value;

const name = document.getElementById("name");
const birth = document.getElementById("birth");
const fieldYear = document.getElementById("fieldYear");
const num = document.getElementById("num");

name.innerHTML = inName;
birth.innerHTML = inBirth;
fieldYear.innerHTML = inField + "0" + inYear;
num.innerHTML = inNum;

}

function loadImage(event){
const image = document.getElementById("imgDisplayed");
image.src = URL.createObjectURL(event.target.files[0]);

}

Explainatiob below:
getElementById() is the method returns an Element object representing the element whose id property matches the specified string, so we are graping the id of all the element(students details)

The second codes of getElementById() grasp element to display
after graping you create the varibles comparing the values of the students data.

lastly, the function of onclick the preview
