Show Hidden javascript breaking forms

[OverlordQ]

here it is edited for readability:

javascript:(
function(){
	var i,f,j,e,div,label,ne; 
	for(i=0;f=document.forms[i];++i)
		for(j=0;e=f[j];++j)
			if(e.type==%22hidden%22){ 
				D=document; 
				function C(t){
					return D.createElement(t);
				} 
				function A(a,b){
					a.appendChild(b);
				} 
				div=C(%22div%22); 
				label=C(%22label%22); 
				A(div, label); 
				A(label, D.createTextNode(e.name + %22: %22)); 
				e.parentNode.insertBefore(div, e); 
				e.parentNode.removeChild(e); 
				ne=C(%22input%22);
				ne.type=%22text%22; 
				ne.value=e.value; A(label, ne); 
				label.style.MozOpacity=%22.6%22; 
				--j;
			}
}
)

That's what I found somewhere, the problem is, all the hidden fields, after running this java script, dont get submitted with the form anymore. Any help would be most appreciated.

That's because it removes them, I think

e.parentNode.removeChild(e);

Yea but right after that is:

				ne=C(%22input%22);
				ne.type=%22text%22; 
				ne.value=e.value; A(label, ne);

the C function creates a new 'input' element changes the type to text and then set's the value of the old element to the new element . . .
