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

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

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

let 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:

input.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:

let 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:

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