Tabia za prototype ya JavaScript Date

Muhtasari na matumizi

prototype Mtofauti wa maadili umekuwa kusaidia kuingiza tabia na maadili mpya kwenye kifaa cha Date().

Kwenye maandiko ya tabia, tabia zote za taarifa za tarehe zitaingizwa tabia na maadili yake, kama thamani ya kuzungumza.

Kwenye maandiko ya mtumishi, tabia zote za taarifa za tarehe zingoweza kutumika hii methodi.

Mafikirio:Date.prototype haaminika kipimo cha tarehe kina, bali kinaaminika kipimo cha kina cha Date() kina.

Mafikirio:Prototype ni kifaa cha ujenzi cha kawaida, kinapatikana kwa madai all ya JavaScript.

Mfano

Votisha mtu mpya wa tarehe, na kufunza kipimo cha tarehe kwa jina la myProp:

Date.prototype.myMet = function() {
  if (this.getMonth() == 0){this.myProp = "January"};
  if (this.getMonth() == 1){this.myProp = "February"};
  if (this.getMonth() == 2){this.myProp = "March"};
  if (this.getMonth() == 3){this.myProp = "April"};
  if (this.getMonth() == 4){this.myProp = "May"};
  if (this.getMonth() == 5){this.myProp = "June"};
  if (this.getMonth() == 6){this.myProp = "July"};
  if (this.getMonth() == 7){this.myProp = "August"};
  if (this.getMonth() == 8){this.myProp = "September"};
  if (this.getMonth() == 9){this.myProp = "October"};
  if (this.getMonth() == 10){this.myProp = "November"};
  if (this.getMonth() == 11){this.myProp = "December"};
};

Votisha kipimo cha Date, na kufanya mtu wa mtu kwa mtu myMet:

var d = new Date();
d.myMet();
var monthname = d.myProp;
