感觉自己的实现好啰嗦

var s = document.getElementById('test-list');
var x=[], i;
for (i=0; i<s.children.length; i++)
{
    x.push(s.children[i].innerText);
}
x.sort();

var y, z, text, ne;
y = document.createElement('ul');
for (z=0; z < x.length; z++)
{
    text = x[z];
    ne = document.createElement('li');
    ne.id = text;
    ne.setAttribute('class','lang');
    ne.innerText = text; 
    y.appendChild(ne);  
}
s.innerHTML=y.innerHTML;
alert(s)
