</select>





</br>
BLA BLA BLA test font




<input type=button value="Go!" onClick="javascript:changeBG(this)">

</form>

</body>

</html>

the only one that works just the background color

can u guys help me with this?

thank you

well since background works, why not use the same location.href? You are also making use of deprecated code, you might want to rethink how you are changing the properties.

it is not working
i can change the font type using button click
but i cannot use combo box

<a onClick=document.getElementById('hey').style.fontFamily='verdana'> Make it VERDANA!!!</a>

this code change the text with <body id=hey>

and then the text inside body change

but i cannot get the font style into the combobox(listbox)

what makes you think there is such a thing as document.fontFamily?
as I said, make sure you are using up-to-date and correct properties.

You can try this one...
