JavaScript da mahsulotlar kalkulyatorida qayta hisoblash bilan tahrirlash

Keling, endi allowEdit funktsiyasini oldingi darsda tavsiflangan qayta hisoblash bajariladigan qilib takomillashtiramiz.

Hozircha sizning funktsiya kodingiz taxminan shunday ko'rinishda bo'lishi kerak:

javascriptfunction allowEdit(td) {
  td.addEventListener('dblclick', function() {
    let text = td.textContent
    td.textContent = '';
    
    let input = document.createElement('input');
    input.value = text;
    input.focus();
    td.appendChild(input);
    
    input.addEventListener('keydown', function(event) {
      if (event.key == 'Enter') {
        td.textContent = this.value;
      }
    });
  });
}

Keling, narx va miqdor kataklari uchun qayta hisoblashni bajaradigan kodni qo'shamiz:

javascriptfunction allowEdit(td) {
  td.addEventListener('dblclick', function() {
    let text = td.textContent
    td.textContent = '';
    
    let input = document.createElement('input');
    input.value = text;
    input.focus();
    td.appendChild(input);
    
    input.addEventListener('keydown', function(event) {
      if (event.key == 'Enter') {
        td.textContent = this.value;
        
        if (td.classList.contains('price') || td.classList.contains('amount')) {
          // qayta hisoblashni bajaramiz
        }
      }
    });
  });
}
