Am gasit pe net un select destul de bun si util , l`am modificat cat am putut dar intampin o problema destul de dubioasa. Copiati codul intr`o pagina simpla htm si veti vedea ca totul functioneaza mai putin o categorie si anume "Desktop". daca se sterg ultimile 4 randuri de la array merge si categoria respectiva. are cineva idee cam care este cauza? si acum sa postez taota polologhia:

Incearca sa faci testul de la linia 170 :
if(field1.options[field1.selectedIndex].value >= catlist[loop_start+Math.round((loop_end-loop_start)/2)][1]) {

sincer..nu am inteles maim nimik. Poti fi mai explicit?

[humeniuc]

testul respectiv, cum il faci tu, e doar cu ">".
si se intampla ca pentru sectiunea pe care o cauti care are id = 3 testul sa nu se comporte cum trebuie.
fa testul cu ">=" si o sa functioneze. la mine a functionat.

dar oricum, algoritmul de selectie a subelementelor e destul de ciudat.

vezi cum merge la http://humeniuc.go.ro/test.html

[Mascka]

Multumesc foarte mult.. da merge...
