Javascript: add attribute in for ... in statement
When I use here the direct ".attribute" form in the inner for-loop (commented line) it doesn't work. How do I have to rewrite the commented line to get the direct ".attribute" form working?

Your question is a bit unclear, but I think you just need to use bracket notation, as you do elsewhere:
for (attr in data[name])
{
input[attr] = data[name][attr]; // <---
input.setAttribute( attr, data[name][attr] );
}
