There is a problem with this. *Names* of input controls are only
meaningfull in the scope of the form they are in. Two different forms
can have controls with the same names. That means that a *name* is not
necessarily unique for elements in a page. The id attribute should
give unique identifiers, but you don't always use those on input elements.

With that in mind, here is a function:
---
function setReadOnly(names,scope) {
scope = scope || document; // default to document
var hasGEBN = Boolean(scope.getElementsByName);
for (var i=0;i<names.length;i++) {
var elems = hasGEBN?scope.getElementsByName(names):
scope.all[names];
for (var j=0;j<elems.length;j++) {
elems[j].readOnly = true;
}
}
}
