JavaScript-da URLSearchParams yordamida AJAX orqali ma'lumotlarni yuborish

Query String-ni qo'lda shakllantirish har doim qulay emas. Buni URLSearchParams orqali amalga oshirish ancha qulay:

public/client.jsbutton.addEventListener('click', function() {
  let searchParams = new URLSearchParams();
  
  searchParams.set('num1', '1');
  searchParams.set('num2', '2');
  
  let promise = fetch('/handler/', {
    method: 'post',
    body: searchParams,
  });
});
