<Form ondblclick = "" name = "form1">
<Input type = "text" name = "AB/cd" id = "bt"> <input type = "button" value = "Click" onclick = "setValue (); ">
</Form>

Function setValue ()

// Document. form1. AB/cd. value = "1234"; in this case, an error is returned.
Document. getElementById ("bt"). value = "123 ";
}
</Script>
