Issues with jplayer integration

[strawberry 3.141]

@aries1984 In general adding a script in the getDom function isn’t good. It should be done in getScripts similar too:

Module.register("MMM_Webradio", {
	defaults: {
		text: "Playing Radio!"
	},

        getScripts: function() {
                return [
                        "http://code.jquery.com/jquery-1.11.1.min.js",
                        "http://jplayer.org/latest/dist/jplayer/jquery.jplayer.min.js",
                        this.file("jPlayer.js");
                ];
        },

	getDom: function() {
		var wrapper = document.createElement("div");

		var displayedText = document.createElement("div");
		displayedText.innerHTML = this.config.text;
		displayedText.setAttribute("id", "jquery_jplayer_1");
		displayedText.setAttribute("class", "jp-jplayer");
		wrapper.appendChild(displayedText);

		return wrapper;
	}
});

Be aware of that you most likely need to init your player after the getdom function was executed. Otherwise the player will not find your wrapper. Also as soon as the module gets rerendered, The player most likely need to reinitialized.

@aries1984 I would open the debug console and see if there are any errors.

Ctril-shift-i (letter i)

Select the console table

Also look at the scripts tab to make sure things are loaded like u expect

Thanks for your hint. I do have indeed errors:

jplayer.org/latest/dist/jplayer/jquery.jplayer.min.js:2 Uncaught TypeError: Cannot read property 'fn' of undefined
  at jplayer.org/latest/dist/jplayer/jquery.jplayer.min.js:2    
  at jplayer.org/latest/dist/jplayer/jquery.jplayer.min.js:2    
  at jplayer.org/latest/dist/jplayer/jquery.jplayer.min.js:2

:8080/modules/MMM_Webradio/jPlayer.js:1 Uncaught ReferenceError: $ is not defined    
  at :8080/modules/MMM_Webradio/jPlayer.js:1

as I said…it is really strange that exactly the same DOM works in a plain HTML-file perfectly.

Thanks for that, too. I’ve tried it in the getScripts function already as well. That was my first try. But the 2 scipts need to be loaded before the main script gets excecuted. But I’ll give it another shot.

@aries1984 the getScripts method is called before getDom(), so they are ‘loaded’ into the browser space.

you should be able to check that they are loaded with the scripts tab of the debug console window

@sdetweil
jep…got it now via the getScripts method. They are now even loaded in the right order: first jQuery, then jPlayer, then my own script -> leads me to exactly the same errors in the console window.

jplayer

still stuck with the same errors. Replacing ‘$’ with ‘jQuery’ throws the same error saying “jQuery is not defined”.
Scripts are definitely loaded in the correct order, too.

What really confuses me is that the simple HTML page works perfectly. Any other thoughts? I’ve searched the web for the last 2hrs and could not find a solution, yet…will keep looking, though.

Right…I’ve downloaded jPlayer now locally and I’m loading the scripts locally. Now the errors are gone but it looks like I’ve made a mistake before when loading them online.

Anyway, the errors are now gone but there is still no sound output. As mentioned initially I am quite new to developing a module so I’m really sorry if things seem obvious for you…but belive me, they’re not so obvious for me. But I’m very keen to learn!

The jPlayer script I’ve wrote myself looks like this:

$(document).ready(function() {

    var stream = { mp3: "http://media-ice.musicradio.com/CapitalSouthCoastMP3" },
    ready = false;

    $("#jquery_jplayer_1").jPlayer({
        ready: function(event) {
		ready = true;
		$(this).jPlayer("setMedia", stream);
		$(this).jPlayer("play", 1);
        },

	pause: function() {
		$(this).jPlayer("clearMedia");
	},

	error: function(event) {
		if(ready && event.jPlayer.error.type ===$.jPlayer.error.URL_NOT_SET) {
			// Setup the media stream again and play it.
			$(this).jPlayer("setMedia", stream).jPlayer("play");
		}
	},

        swfPath: "http://jplayer.org/latest/dist/jplayer",
        supplied: "mp3",
	preload: "none",
	volume: 1,	
	wmode: "window",
	useStateClassSkin: true,
	autoBlur: false,
	keyEnabled: true,

    });
});

@strawberry-3-141, @sdetweil
Thanks for your help and pointing me into the right directions. In the last 2 weeks I made massive steps forward with my first ever module. You’ve helped to get my head round havascript and to understand it better. Thanks!

End result can be found here.
