Hello Experts,

Probably being thick - but here goes:

I have a few of these html inputs:

<form name="myform">
<input type="file" name="myfile[]" />
<input type="file" name="myfile[]" />
<input type="file" name="myfile[]" />
</form>

Using javascript, how do I output
a) the number of elements (3 in this case)
b) the values assigned to these elements.

I tried:

var files =document.myform.elements["myfile[]"];				
for (i = 0; i < files.length; i++)
{   			
    filename = files[i].value;
}

However, the file length is undefined.
I cannot change the name of the input variable from myfile[] for legacy reasons.

Many Thanks!
