arrived here while investigating why mask code causing errors in ie8.
again, parser doesn't closing curly of block:
$.mask = { //predefined character definitions definitions: { '9': "[0-9]", 'a': "[a-za-z]", '*': "[a-za-z0-9]" }, dataname: "rawmaskfn", placeholder: '_', }; any appreciated!
maybe because of additional comma after placeholder: ... line?
