Listbox unselect

[tjbarr]

Simple Question
How do I allow the user to unclick a choice on a listbox?

If they click on it again it should unselect it.

It doesn't. Here is my code - this is on a php page.

<p align="left"><font face="Arial, Helvetica, sans-serif" color="#0000A0">Please
select the States of your interest: </font><br>
<select name="cbostate[]" size="auto" multiple class="listbox">
<?php

/
Create your SQL statement
/

$sql="SELECT fip_code, fip_name from tbl_fip_codes WHERE reg_id =2 Order by fip_name;";
$result_set = pg_Exec ($conn, $sql);
$rows = pg_NumRows($result_set);

if ((!$result_set) || ($rows < 1)) {
//No connection or no rows returned, so print an error
echo "<H1>ERROR - no rows returned</H1><P>";
exit; //exit the script
}

for ($j=0; $j < $rows; $j++) {
echo "<option value=".pg_result($result_set, $j, "fip_code")."> ".pg_result($result_set, $j, "fip_name")."</option>";
} }

?></select>

Must click+CTRL

Is there a way to make this automated without the ctr key?

mh 😕 ,
try this little javascript:

for (var i = 0; i < select.options.length; i++) 
{ 
  if (select.options[i].selected)select.options[i].selected=false;
}

but must link this to an event such click on a link, paragraph, button, etc..

See you

p.s: because you use "cbostate[]" as name you must access this object through
form[] array or "this" object...
