Dobry den.

function popsel2(choice,id){
var value_options=new Array();

value_options[1]="58".split(',');
name_options[1]="Bosna a Hercegovina".split(',');
value_options[3]="60".split(',');
name_options[3]="Nikózia".split(',');
value_options[4]="61".split(',');
name_options[4]="Santo Domingo".split(',');
value_options[18]="75".split(',');
name_options[18]="Praha".split(',');
value_options[5]="62".split(',');
name_options[5]="Káhira".split(',');
value_options[6]="63".split(',');
name_options[6]="Atény".split(',');
value_options[8]="65".split(',');
name_options[8]="Jeruzalem".split(',');
value_options[10]="67".split(',');
name_options[10]="Valleta".split(',');
value_options[11]="68".split(',');
name_options[11]="Rabat".split(',');
value_options[19]="76".split(',');
name_options[19]="Varšava".split(',');

name_options[17]="Bratislava".split(',');
value_options[12]="69".split(',');
name_options[12]="Belehrad".split(',');
value_options[13]="70".split(',');
name_options[13]="Rím".split(',');

name_options[14]="Tunis".split(',');
value_options[15]="72".split(',');
name_options[15]="Ankara".split(',');
value_options[16]="73".split(',');
name_options[16]="Londýn".split(',');
value_options[9]="66".split(',');
name_options[9]="Madrid".split(',');
document.forms[0].id.options.length=0;
topop=value_options[choice];
topop2=name_options[choice];
document.forms[0].id.length=topop.length;
for (i=0;i<topop.length;i++){
document.forms.example.id.options[i].text=topop2[i];
}
}

volanie v HML:
<select name='ID_stat' id='ID_stat' onchange="popsel2(this.options[this.selectedIndex].value,'IDM_odchod') ">
<option value='0' selected='selected'>------------------------------</option>
<option value='1'>Bosna a Hercegovina</option>
<option value='2'>Bulharsko</option>
<option value='7'>Chorvátsko</option>

<option value='16'>Veľká Británia</option>
<option value='9'>Španielsko</option>
</select>
</td>
<td><label for='IDM_odchod'>Odchodu(Mesto)</label><br />

<select name='IDM_odchod' id='IDM_odchod'>
</select></td>

Dakujem velmi by mi to pomohlo.

Ono mi to funguje aj teraz a aj predtym, data som vsetky neudaval, ale prave to ID, ktore som chcel predavat, bolo ID objektu na stranke...cize IDM_odchod a ta ista funkcia, a naplnenie tymi istymi datama pre select IDM_prichod vid. html:

<td><label for='IDS_odchod'>Odchod(Štát)</label><br />
<select name='IDS_odchod' id='IDS_odchod' onchange="popsel4(this.options[this.selectedIndex].value)">
<option value='0' selected='selected'>------------------------------</option>
<?php
foreach ($stat as $key => $value)
{ ?>
<option value='<?php echo $key; ?>'><?php echo $value?></option>
<?php } ?>
</select>
</td>
<td><label for='IDM_odchod'>Odchod(Mesto)</label><br />
<select name='IDM_odchod' id='IDM_odchod'>
<option id='option'>------------------------------</option>
</select>
</td>
<td><label for='IDS_prichod'>Príchod(Štát)</label><br />
<select name='IDS_prichod' id='IDS_prichod' onchange="popsel4(this.options[this.selectedIndex].value)">>
<option value='0' selected='selected'>------------------------------</option>
<?php
foreach ($stat as $key => $value)
{ ?>
<option value='<?php echo $key; ?>'><?php echo $value?></option>
<?php } ?>
</select>
</td>
<td><label for='IDM_prichod'>Príchod(Mesto)</label><br />
<select name='IDM_prichod' id='IDM_prichod'>
<option id='option'>------------------------------</option>
</select>
</td>
