الزيارات: أكواد الآلات الحاسبة لمدونة البلوجر

السلام عليكم ورحمة الله تعالى وبركاته

اليوم سوف نعرض كيفية عمل آلة حاسبة إلكترونية باستخدام أكواد الجافا سكربت.

تعتبر الجافا سكربت من اقوى اللغات فى تطوير الويب ومن اكثرها سهولة، وفي هدا الدرس سنعرض مجموعة من الألات حاسبة قمت بنسخ اكوادها من مواقع اجنبية بحيت نقوم بوضع الاكواد في القالب الا اني طورتها وقمت بتجميع اكواد Css، HTML، JS ووضعتها في كود واحد يسهل على المدون او الزائر بوضعها داخل Java Script او داخل المنشور في جهة HTML او في الصفحة، عوض عن وضعها في القالب في الجهات المخصصة.

سنعرض الان اكواد الالات الحاسبة، على بركة الله.

طريقة التركيب:
1- لوحة التحكم بلوجر.
2- تخطيط.
3- إضافة أداة HTML/JavaScript .
4- ثم ضع الأكواد المختارة في الحقل

أو

1- مشاركة.
2- تحرير.
3- انتقال من خانة تأليف الى خانة HTML.
4- ثم ضع الأكواد المختارة.

أو

1- صفحات.
2- صفحة جديدة.
3- خانة HTML.
4- ثم ضع الأكواد المختارة.

بالنسبة الى طريقة التركيب تبقى لصاحب المدونة طريقته الخاصة اما بالنسبة للمحترفين فيمكن تركيبها حتى في القالب.

اتمنى ان تنال اعجابكم
