i需要以下查询帮助。

I am trying below javascript but it didnt work for me

<script language="javascript" type="text/javascript">
    function validate() {



           re= /^([a-zA-Z+]+[0-9+]+[&@!#+]+)$/ ;
        if (!re.test(document.getElementById("txtNewPassword").value)) {
            alert("Your new password does not comply with the password policy" + '\n' + "" + '\n' +  "-must contain at least 6 characters" + '\n' + "-must contain at least one number (0-9)" + '\n' + "-must contain at least one character" + '\n' + "-must contain at least one special character (@#$%)");
                       document.getElementById("txtNewPassword").focus();
            return false;
        }


        else {
            return true;
        }
    }
</script>
