window.opener with <select>

[John]

Hi

There is a <select name='city'> item with <option> in the HTML <form
name='france'>
I have tried using the following in a JS routine:
<a
href="javascript:window.opener.document.france.city.options[21].selected=true;
window.close();"></a>

I get
Error Line 0
'window.opener.document.france.city.options.21 is null on not an object

Is the syntax correct?

I have tried the following on an <input type='text' and it works OK.
<a href="javascript:window.opener.document.france.industry.value='iron';
window.close();"></a>

Regards
John

probably you haven't 22 options in this select ?

href="javascript:if(window.opener.document.france.city.options[21])
window.opener.document.france.city.options[21].selected=true"

href="javascript:if(window.opener.document.france.city.length>21)
window.opener.document.france.city.options.selectedIndex=21"

Je pense que vous avez trouve la reponse. If me faut verifier le nombre des
<option>s qui existent.
Merci.
