#1

Hi!
I use the dhtmlxCombo script with the xml loading :

var z=new dhtmlXCombo("combo_zone2","alfa2",194, 'image'); z.loadXML("../myxml.xml");
Everything works fine, but I want to select a certain item with javascript…how can I do that?
This should works…

z.setComboValue(<?php echo $status;?>); but indeed not!

Thanks for your help!

Hello

setComboValue method should be called after xml loading - the second parameter of the loadXML method:

z.loadXML("…/myxml.xml",function(){

 z.setComboValue(<?php echo $status;?>);

})

Hello,

when the groups extension is used, the xml depends on selection in parent combo. Instead of using groups you may try to use onChange event. Here is the full answer:
