i've developed audio player plays radio station's stream. host audio on streamon , when click play button in player in lower right of streaming widget audio, after buffering, plays via inserting iframe styled invisible. however, people on staff have complained if click on play button multiple times whilst it's loading, play multiple streams (as can seen here: glitched page ). so, on test page attempted below code prevent such scenarios occuring. however, audio isn't being loaded on requested (as can seen here: test page ). appreciated. <script> $playing = 0; $(document).on("click", "button#mute", function(){ $('iframe#audiostreamon').remove(); $playing = 0; }); if ($playing =0) { $(document).on("click", "button#play", function(){ $(this).after('<iframe id=...

i want upload files ajax. in past accomplished using magical jquery form plugin , worked great. i'm building rails app , trying things "the rails way" i'm using form helper , paperclip gem add file attachments. the rails docs warn form helper not work ajax file uploads: unlike other forms making asynchronous file upload form not simple providing form_for remote: true. ajax form serialization done javascript running inside browser , since javascript cannot read files hard drive file cannot uploaded. common workaround use invisible iframe serves target form submission. it seems clear there's no off-the-shelf solution. i'm wondering what's smartest thing do. seems have several options: use form helper , iframe trick. use form helper + load jquery form plugin submit file (not sure if play nice rails's authenticity token, etc) use form helper + paperclip + [some other gem] extend it's functionality allow ajax form submissi...
