i tried making a class to create some transactions. I wanted to fill out the values. whenever the button was clicked it would trigger the this.handleClick function to create a new transaction and log this to the console. however, the page automatically reloads whenever i submit the values. what am i doing wrong? here is code used.
class Transaction {
constructor(getal, afzender, ontvanger) {
this.getal = getal;
this.afzender = afzender;
this.ontvanger = ontvanger;
// Set the clicker
this.button = document.getElementById('clicker');
this.button.addEventListener('click', this.handleClick.bind(this));
}
print() {
console.log(`${this.afzender} sent ${this.getal} bits to ${this.ontvanger}`);
}
emptyInputs() {
document.querySelector('#bedrag').value = '';
document.querySelector('#verzender').value = '';
document.querySelector('#ontvanger').value = '';
}
handleClick(event) {
event.preventDefault();
const p = document.querySelector('.confirmation');
p.style.color = 'green';
const bedrag = document.querySelector('#bedrag').value;
const verzender = document.querySelector('#verzender').value;
const ontvanger = document.querySelector('#ontvanger').value;
const transaction = new Transaction(bedrag, verzender, ontvanger);
transaction.print(); // Optionally, print the transaction details
transaction.emptyInputs(); // Clear the input fields
p.innerText = "Transaction made!";
}
