Hi Mark.
I need you to know that I am not expecting you to help me, but I greatly appreciate any bit of your help very much. HTML5 Music Player is a free 3rd part plugin that has no support. Before joining this forum I contacted the developer and this is what he wrote:
You're correct, I don't provide support for these resources.
I don't know the answer to your question, I would need to do some research, but
I believe your intuition is correct. You probably just need to call
jPlayer('play') on the specific jplayer instance. I would imagine I'm
initializing jPlayer something like $myJPlayer.jPlayer(), so you would need to
do something like $myJPlayer.jPlayer('play').
I originally thought that it will take no time to make it work, that is why I tried to contact Saleem and now I am on this forum talking to you.
Now back to your message. I have tried to use onClick=$('jquery_jplayer').jPlayer('play'); but it does not work. Also as per developer guide I was wondering if there should be "#" before the player's id like this onClick=$('#jquery_jplayer').jPlayer('play');. Anyway I have tried both options and they don't work. You said that this plugin is using the older version of jPlayer 2.0.9. I was wondering if I should forget about the plugin I am using right now (it would be hard because I have spent many hours tweaking it) and try to do it from scratch with newly download jPlayer, or should I pursue and try to find this magic formula that will make this player PLAY. Can you tell me how easy it is to create a simple skin like this (see the picture) for a guy like me that does not know Java, jQuery, but can copy, paste the necessary code and tweak things in CSS and HTML:

I just need a simple player (see the picture) with PREV, PLAY/PAUSE, NEXT buttons, progress bar and support for a playlist, and that it will work well on PC, Android and iOS devices. Maybe you can suggest a solution that I am not aware of. I have spent days in looking for a friendly, simple music player that will meet my simple demands and the only solution was the HTML5 Music Player (with no support). I don't mind donating if I get what I need.
Thank you again for your valuable time.
