Date.prototype.setDate() | دالة تعيين التاريخ

دالة setDate() تقوم بتعين يوم من الـ Date المحدد نسبه إلي الشهر المحدد.

بنية الجملة

dateObj.setDate(dayValue [رقم اليوم])

المعاملات (Parameters)

dayValue
يجب أن يكون عدد صحيح يمثل يوم من الشهر. علي سبيل المثال setDate(15) .

القيمة العائدة

عدد المللي ثانية بين تاريخ 1 يناير 1970 00:00:00 UTC والتاريخ المحدد (يتغير الـ Date أيضا بتغير المكان [المنطقة الزمنية]).

الوصف

إذا كان dayValue [رقم اليوم] خارج نطاق قيم الشهر المحدد لهذا التاريخ، فأن دالة setDate() ستقوم بتحديد الـ Date [اليوم] وفقاً لذلك. علي سبيل المثال، إذا تم تحديد dayValue [رقم اليوم] إلي 0 فسيتم تعيين التاريخ إلي أخر يوم في الشهر السابق.

أمثلة

استخدام setDate()

var theBigDay = new Date(1962, 6, 7); // 1962-07-07
theBigDay.setDate(24);  // 1962-07-24
theBigDay.setDate(32);  // 1962-08-01
theBigDay.setDate(22);  // 1962-08-22
theBigDay.setDate(0); // 1962-06-30
theBigDay.setDate(98); // 1962-10-06
theBigDay.setDate(-50); // 1962-08-09
