One DROPDOWN SELECT control can it fill in 2 textboxes?

[Erwin Radermacher]

Hello dear PHP users,
I have a form with text boxes and a dropdown menu with names of cities
The adjacent textbox fills by the help of a Javascript function.
My question is, how to realize the purpose of filling the adjacent texbox
for zip values.

Or say it otherwise: how to transfer an array, filled with php to a
Javascript function.
<code>

<table>
<form name="form1" action="saved.php" method="POST">
<tr><td>Name</td><td><input type="text" name="LastName" value="<? echo
$LastName ?>"></td></tr>
<tr><td>Vorname</td><td><input type="text" name="Firstname" value="<?
echo $FirstName ?>"></td></tr>
<tr><td>Address</td><td><input type="text" name="Address" value="<? echo
$Address ?>"></td></tr>
<tr><td>ZIP</td><td><input type="text" name="ZIP" value=""></td></tr>
<tr><td>&nbsp;</td><td>

<select size="5" name="ListofCities" onChange="GiveCity()">

<?
for ($i=0; $i<$countcities; $i++)

{
echo "<option
value="."'"."$arraycities[$i]"."'"."</option>$arraycities[$i]";
}
?>

</select></td></tr>";

<tr><td>City</td><td><input type="text" name="City" value="" ></td></tr>

</code>

and the Javascript function is:
function GiveCity()
{
mycity=
document.form1.ListofCities.options[document.form1.ListofCities.options.sele
ctedIndex].value;
document.form1.City.value = mycity;

}
What I want is how to fill in by the same function the zip-textbox with the
corresponding value of the zip

Or how to fill it in with a twodimensional array

as

by example $locations = array("1000", "Brussels", "3000", "Leuven", "4000",
"Liege");

may I give an array in php to a Javascript function?
Thanks for helping.
