Enable/Disable checkbox

Pozdrav.
Imam textfield i pokraj njega checkbox, i htio bi da mi checkbox bude disabled sve dok ne upisem bar jedno slovo ili broj u taj textfield. Ako netko zna kako se to radi? Hvala

Evo npr. ovako nekako mi to izgleda:

Code:

<td><input name="ime" type="text" /></td> 

<td><input type="checkbox" name="checkbox1" disabled/></td>

RE: enable checkbox

U head dio:

Code:

function vrijednost(tekst)

       {

        if(tekst=="") 

        {

                cbox = document.getElementById("checkbox");

                cbox.checked = false;

        }

        else 

        {

                cbox.checked=true;

        }

      }

A u body dio:

Code:

<td><input name="ime" type="text" id="polje" onBlur="vrijednost(this.value);"/></td>

<td><input type="checkbox" name="checkbox1" id="checkbox"></td>

RE: enable checkbox

<html>

<head>

<script type="text/javascript">

function vrijednost(tekst)

       {

        if(tekst=="")

        {

                cbox = document.getElementById("checkbox");

                cbox.checked = false;

        }

        else

        {

                cbox.checked=true;

        }

      }

</script>

</head>

<body>

<table>

<tr>

<td><input name="ime" type="text" id="polje" onBlur="vrijednost(this.value);"/></td>

<td><input type="checkbox" name="checkbox1" id="checkbox"></td>

</tr>

RE: enable checkbox

Nisi, sorry, ja sam krivo razumio pitanje.... Stavio sam ti checkiranje umjesto enable/disable. Evo koda.

Code:

<html>

<head>

<title> www.tutorijali.net </title>

<script type="text/javascript">

function vrijednost(tekst) 

    {

        if(tekst!="") 

        {

                cbox = document.getElementById("checkbox");

                cbox.disabled = false;

        }

        else 

        {

            cbox.disabled = true;

        }

    }

</script>

</head>

<body>

<td><input name="ime" type="text" id="polje" onBlur="vrijednost(this.value);" /></td>

<td><input type="checkbox" name="checkbox1" id="checkbox" disabled="true" /></td>

</body>

</html>

<head>

<title> www.tutorijali.net </title>

<script type="text/javascript">

function promijeni(broj) 

    {

        polje = document.getElementById("polje" + broj).value;

        cbox = document.getElementById("checkbox" + broj);

        if(polje!="") 

        {

            cbox.disabled = false;

        }

        else 

        {

            cbox.disabled = true;

        }

    }

</script>

</head>

<body>

<input name="ime" type="text" id="polje1" onChange="promijeni('1');" />

<input type="checkbox" name="checkbox1" id="checkbox1" disabled="true" />
