Flash/actionscript 3 open url into an iframe

I just got an alert about this post where guys discussing open URL into an iframe. Yea, thing will work, but as long as you doing just one URL per time.

My recommendation, - don't use this navigateUrl method, instead "talk" to your JavaScript, like I do in following example:

for (var i:Number = 0; i<listRates.dataProvider.length; i++)
{
    if (listRates.dataProvider[i].selected == true)
    {
        trace("url:" + listRates.dataProvider[i].url + "&checkin=" + 
dateArrival.text + "&checkout=" + dateDeparture.text);
        ExternalInterface.call("window.open", listRates.dataProvider[i].url + 
"&c1=" + date1.text + "&c2=" + date2.text, "checkProvider" + i);                
    }
}

Want to know why? Simple, Once you trying to do navigateUrl within a loop you application might accidentally lose the action and "forget" to open some of the browser windows your requested in this loop. So once you do it via ExternalInterface, you won't have problems anymore, leave some work to do for the browser as well, don't be greedy.
