Hi,

I am try to write some validation script using javascript and prototype.

What I want to do is to loop through all the elements of a form and validate each answer. My code works, BUT the array of DOM elements is unsorted. I would like to sort the elements by their ID.

Here is the my code, which works fine if I comment-out elem.sort(zelementsort);

function zelementsort(a,b) {
    if (a.name > b.name)
    	return -1;
    else if (b.name > a.name)
    	return 1;
    else 
    	return 0;
}   

var elem = document.getElementById('myform').elements;
elem.sort(zelementsort);

for(var i = 0; i < elem.length; i++)
{
     alert("Name = " + elem[i].name);

}

I wonder if the problem might be that some of the elements do not have names. Anyone have another simpler way of sorting an array of DOM elements by their .name?
