chodzi o fragment:
- Kod: Zaznacz cały
this.xmlHttp.onreadystatechange = function()
{
tmpObj.getResponse();
}
Działa pod FF, IE (6 i 7), ale pod SM nie chce, siedzę nad tym już sporo czasu i nie wiem czemu, nie rozumiem
jakby ktoś miał jakiś pomysł to byłbym wdzięczny
cała biblioteka wygląda tak

a jej użycie wygląda tak
- Kod: Zaznacz cały
var url ='http://localhost/projekt/index.php?action=action1';
var ajaxObj = new Ajax();
ajaxObj.sendRequest(url,'','GET',false);
var ajaxRetVal = ajaxObj.getAjaxResult();
if(ajaxRetVal==1)
{
var ajaxRet = ajaxObj.getRequestResult();
//i tutaj z rezultatem mozna zrobić co się chce
}
