getElementsByTagName
The getElementsByTagName() method accesses all elements with the specified tagname.
Example:
// Get the list items and setup an array for sorting
var lis = ul.getElementsByTagName(“LI”); var vals = [];
// Populate the array
for(var i = 0, l = lis.length; i < l; i++)
vals.push(lis[i].innerHTML);
// Sort it
vals.sort();
// Sometimes you gotta DESC if(sortDescending) vals.reverse();
// Change the list on the page
for(var i = 0, l = lis.length; i < l; i++) lis[i].innerHTML = vals[i];
