JQuery :: Create A Small Input Box That Changes The Form Action?

I've been trying to create a small input box that changes the form action based upon what the user enters. I can get these two options to work:

1. If value IS NOT 123456code, then action should be search-results.html.

$("form.filterform").keyup(function(){
if($("input.searchbox_resources").val()!="123456code"){
$("form.filterform").attr("action","search-results.html");
}
});

2. If value IS 123456code, then action should be search-results.html.

$("form.filterform").keyup(function(){
if($("input.searchbox_resources").val()==="123456code"){
$("form.filterform").attr("action","error.html");
}
});

I want to replace option 2 with a variation... where the user gets the error.html page if what they typed contains 123456code. As it stands currently, option 2 requires that a person types in that code exactly with no differences at all.

I was thinking it should look like this:

$("form.filterform").keyup(function(){
if($("input.searchbox_resources").val()*="123456code"){
$("form.filterform").attr("action","error.html");
}
});

But that does not seem to work.
