希望我的代码对您有所帮助。如果您有任何疑问，请问我-写评论。

var deletes = document.querySelectorAll('.delete'),
    dones = document.querySelectorAll('.done');
    
//convert NodeList to array for IE
deletes = [].slice.call(deletes, 0);
dones = [].slice.call(dones, 0);

deletes.forEach(function(removeTodo)
{
    removeTodo.addEventListener('click', function()
    {
        var li = removeTodo.parentNode;
        li.parentNode.removeChild(li);
    });
});

dones.forEach(function(doneTodo)
{
    doneTodo.addEventListener('click', function()
    {
        var elStyle = this.previousElementSibling.style,
            value = elStyle.textDecoration;

        elStyle.textDecoration = value == 'line-through' ? 'none' : 'line-through';
        this.title = value != 'line-through' ? 'to do' : 'done';
    });
});

li{margin:5px 0}
li span
{
    display:inline-block;
    white-space:nowrap;
    width:170px;
    overflow:hidden;
    text-overflow:ellipsis;
    vertical-align:middle
}
.delete
{
    border:2px solid #f99;
    color:#f99;
    background-color:#fdd;
}
.done
{
    border:2px solid #6f6;
    color:#6f6;
    background-color:#dfd;
}
.done,.delete
{
    border-radius:50%;
    display:inline-block;
    line-height:12px;
    cursor:pointer;
}

<ul>
    <li><span>Child 1 – "Buy fruits"</span> <b class="done" title="done">&#x2714;</b> <b class="delete" title="delete">&#10799;</b></li>
    <li><span>Child 2 – "Meet parents"</span> <b class="done" title="done">&#x2714;</b> <b class="delete" title="delete">&#10799;</b></li>

    <li><span>Child 6 – "Pay bills"</span> <b class="done" title="done">&#x2714;</b> <b class="delete" title="delete">&#10799;</b></li>
</ul>
