I鈥檝e found the following code on the net that is a basic example of using the sharedObject method to allow users to save data, however I want to enhance this same example so that in the text area, the user can enter different urls and then when each url that the user has entered is clicked it will navigate to that specific page.
I know that allowing a user to merely enter a url into a single text box and then have it link to the relevant site once clicked is a simple process but I want to achieve this within the following example so that users can save their url list, reset their entire list back to blank or perhaps delete each link individually by clicking on it then clicking a delete button.
My main problem is that it seems the selectedItem.text property can鈥檛 be accessed within a text area's click command and it doesn't seem the itemClick function is available in a text area like it can in a TileList for example so I鈥檓 not sure how I can get it to navigate to the contained url of each item when each item is actually clicked. Would the text area need to be changed to another type of component to incorporate this?:-

Saveable List of User-Entered urlsIf this post answers your question or helps, please mark it as such.
You should use a List instead of a TextArea. I've created a custom component to get the URL from the user, and the URLs are displayed in the main app are launchable, and deletable.
I still have to get loading the SharedObject working right, but here is the code so far:

Okay. The shared object works correctly now.Only the main app file had to change. The AddURL component above is fine as is:

Excellent. That's even better than I thought.
I tried for hours to get it done myself but it works great now. Thanks a lot.
I have a strange problem after I've changed this application into an AIR application. When I run it and click the 'Go' button on any of the added urls the site doesn't open. Internet Explorer doesn't even open at all.
The strange thing is this works fine if it's ran as an Flex application so I just can't figure out why it would'nt as an AIR app
I can't look at this right now, but you might want to consider using the HTML control as a popup.
It's ok no worries. I've managed to get it fixed by changing the gotoURL function to:-
聽
public function gotoURL(evt:MouseEvent):void{
{navigateToURL(new URLRequest('http://' + urlList.selectedItem.url))};
}
聽
Works fine now. Cheers.
