Hi,
i’m using a grouplist to navigate a drive where some music files are stored.
I generate an xml with a php script with all the info i need:

The tree is perfectly shown: directories,sub directories and files. Folders are shown first.
I’m now tryng to play all the files in sequence, one after the other.

Problems start when, from within a folder I have to go one level up (->root) and then one level down (->next directory) and start playing the first track of the next directory…
I’m trying to use this code:

    function play_next()
    {
	current_music_id = music_id;
        next_music_id = (parseInt(music_id)+1).toString();
                    
        if($$(\"music\").item(next_music_id)!=undefined)
        {
        	next_music_level = $$(\"music\").item(next_music_id).\$level;

		if(next_music_level==current_music_level)
		{
			current_folder = $$(\"music\").item(current_music_id).fullname.substr(0,$$(\"music\").item(current_music_id).fullname.length-$$(\"music\").item(current_music_id).name.length);
				next_folder = $$(\"music\").item(next_music_id).fullname.substr(0,$$(\"music\").item(next_music_id).fullname.length-$$(\"music\").item(next_music_id).name.length);
				if(next_folder!=current_folder)
				{
					$$('music').on_click.dhx_list_item.call($$('music'),{},$$(\"music\").item(current_music_id).\$parent);
					$$('music').on_click.dhx_list_item.call($$('music'),{},$$(\"music\").item(next_music_id).\$parent);
				}
			}
			else
			{
				if(next_music_level<current_music_level)
					$$('music').on_click.dhx_list_item.call($$('music'),{},$$(\"music\").item(current_music_id).\$parent);
				if(next_music_level>current_music_level)
					$$('music').on_click.dhx_list_item.call($$('music'),{},$$(\"music\").item(next_music_id).\$parent);
			}

            $$('music').on_click.dhx_list_item.call($$('music'),{}, next_music_id);

            // and then i call the "play" method on my player
    	} 
    }

The result is that the next track correctly starts playing BUT no visual feedback is provided to the user…I’m only able to go up from the current folder to the root but could not manage to go down and select the current track…

Any help???

Hi,

Could you attach a demo and explanation how to reproduce the issue in it ? (the demo should not contain server-side scripts).

Dear Alexandra,
the situation is depicted in the image below:

The Folder structure I have is shown in “1”.
What I’m trying to do is:
I’m in the first folder (see 2 in picture above) and listen to the last song in the folder. What I expect next is that once the last song is over, the first track of the next folder starts playing: 3 in picture above.
I’ve successfully managed to obtain this behaviour, that is the first track of the next folder starts playng, BUT I cannot show the user the new track playing (the current track should be highlighted), What I show to the user is “1” again…while I’d like to show him “3”.

Hope to have been clearer this time

Hello,

Unfortunately, the pictures did not make the issue clearer. However, you mentioned that you want to show an item. There is showItem(id) in grouplist. This method opens a folder with an item and scrolls to item position.

$$(“yourList”).showItem(id);

I tried this method last week with no success… :confused: I’ve just tried it again and it works like a charm!!!

Thank you! :mrgreen:
