سلام
من هیچی از جاوا نمیدونم
یه کد mp3 player گرفتم . این فایل JS هست .. مشکل اینجاست که Autoplay نیست
میخوام کاری کنم که به محض لود شدن فایل اتوماتیک آهنگ پخش بشه
ممنون
اینم کد :
/*global $, document, alert*/

1) این کد شما ند جی اس نیست... بلکه جاوا اسکریپته. توی انجمن مربوط به خودش بپرسید....
2) به جای دستکاری این کد می تونید از یکی ازپلیر های موجود که قابلیت هایی که میخواین رو داره استفاده کنید... سرچ کنید توی نت پره

درود
حتما باید روی همین پلیر باشه !
