JavaScript-da ro'yxatni tekshirish uchun o'chirish va tugatish tugmalari

Oldingi darsda vazifalarni yechgandan so'ng sizda quyidagi kod bo'lishi kerak edi:

html<input id="input">
<ul id="list"></ul>

javascriptlet input = document.querySelector('#input');
let list = document.querySelector('#list');

input.addEventListener('keypress', function(event) {
  if (event.key == 'Enter') {
    let li = document.createElement('li');
    li.textContent = this.value;
    list.appendChild(li);
    
    this.value = '';
  }
});

Keling, endi 'o'chirish' va 'bajarildi' tugmachalarini qo'shamiz. Ushbu tugmachalarni span teglari shaklida bajaramiz. Shuningdek, span tegida ish matnini ham joylashtiramiz:

javascriptinput.addEventListener('keypress', function(event) {
  if (event.key == 'Enter') {
    let li = document.createElement('li');
    
    let task = document.createElement('span');
    task.textContent = this.value;
    li.appendChild(task);
    
    let remove = document.createElement('span');
    remove.textContent = 'oʻchirish';
    li.appendChild(remove);
    
    let mark = document.createElement('span');
    mark.textContent = 'bajarildi';
    li.appendChild(mark);
    
    list.appendChild(li);
    
    this.value = '';
  }
});

Keling, shuningdek, har bir span tegiga CSS klasslarini qo'shamiz, shunda ularga CSS orqali murojaat qilishimiz va kerakli go'zallikni qo'shishimiz mumkin bo'ladi:

javascriptlet input = document.querySelector('#input');
let list = document.querySelector('#list');

input.addEventListener('keypress', function(event) {
  if (event.key == 'Enter') {
    let li = document.createElement('li');
    
    let task = document.createElement('span');
    task.classList.add('task');
    task.textContent = this.value;
    li.appendChild(task);
    
    let remove = document.createElement('span');
    remove.classList.add('remove');
    remove.textContent = 'oʻchirish';
    li.appendChild(remove);
    
    let mark = document.createElement('span');
    mark.classList.add('mark');
    mark.textContent = 'bajarildi';
    li.appendChild(mark);
    
    list.appendChild(li);
    
    this.value = '';
  }
});

Qo'shilgan klasslarga CSS qo'shamiz:

css#list span {
  margin-right: 5px;
}
#list .remove, #list .mark {
  color: blue;
  cursor: pointer;
}
#list .remove:hover, #list .mark:hover {
  text-decoration: underline;
}
