change value of text using getElementsByName

I have firstName text that I want to change his value but it not work - 

<input type="text" name="firstName" />
<script LANGUAGE="JavaScript" TYPE="text/javascript">
      document.getElementsByName("firstName").[0].value = "New Value " ;
</script>

How can I change this value ?

Solution

  • That's not syntactically valid JS. Remove the extra .:

    //                                    ↓↓
document.getElementsByName("firstName")[0].value = "New Value " ;
//                                    ↑↑

    and the rest will work.
