Vifungo vya Kufuta na Kukamilisha kwenye Orodha ya Ukaguzi kwenye JavaScript

Katika somo lililopita baada ya kutatua matatizo unapaswa kuwa na mifuatayo ya msimbo:

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 = '';
  }
});

Sasa tuongeze vibonye 'futa' na 'imekamilika'. Tutafanya vibonye hivi kwa kutumia vitambulisho span. Pia kwenye kitambulisho span tutaweka maandishi ya kazi:

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 = 'futa';
    li.appendChild(remove);
    
    let mark = document.createElement('span');
    mark.textContent = 'imekamilika';
    li.appendChild(mark);
    
    list.appendChild(li);
    
    this.value = '';
  }
});

Tutaweka pia madarasa ya CSS kwenye kila kitambulisho span, ili tuweze kuzirejea kupitia CSS na kuongeza urembo unaohitajika:

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 = 'futa';
    li.appendChild(remove);
    
    let mark = document.createElement('span');
    mark.classList.add('mark');
    mark.textContent = 'imekamilika';
    li.appendChild(mark);
    
    list.appendChild(li);
    
    this.value = '';
  }
});

Tuongeze CSS kwa madarasa yaliyowekwa:

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