Problem med select, PHP, Javascript
HejJeg har et problem med en side hvor jeg ved valg i en select liste for 1 af 3 valgmuligheder frem, men hvis jeg ved 2 af mulighederne vil se nogle flere numre så skifter den ikke til de næste 20 numre frem eller tilbage men den bliver ved de samme 20 numre. Er der en der kan se en løsning på dette problem.
<table border="0">
<tr>
<td align="center" class="normal"><b>Vælg Nummer</b></td>
</tr>
<tr>
<td align="center" class="normal">
<script language="JavaScript" type="text/javascript">
<!--
var array_map=new Array();
array_map[0]='extra[nummer]0';//...de cea de-a treia optiune din select
array_map[1]='extra[nummer]14';//id divului afisat de prima optiune din select
array_map[2]='extra[nummer]15';//...de cea de-a doua optiune din select
array_map[3]='extra[nummer]16';//...de cea de-a treia optiune din select
function showhide(){
var array_key=document.menu.extranummer_TYPE.options.selectedIndex;//obtine indexul:0, 1 sau 2 - sunt 3 elemente option
var id_selectat=array_map[array_key];//obtine id-ul div-ului in functie de index
document.getElementById(id_selectat).style.visibility='visible';
//ascunde toate divurile mai putin cel selectat din index
for(var i=0;i<document.menu.extranummer_TYPE.length;i++){
var id_menu=array_map[i];
if(id_menu==id_selectat) continue;//sari peste div-ul selectat
document.getElementById(id_menu).style.visibility='hidden';
}
}

Vælg almindeligt nummer, guld nummer, eller Nummerportering
