Dambudziko guru neTora zvisina kurongeka boolean nderekuti haina kuchengetedzeka. Chero ani zvake ane mukana kune sevha anogona kuburitsa zvimiro zveboolean.
var randomBoolean = Math.random() >= 0.5;
Iyi kodhi mutsara inopa yakasarudzika boolean kukosha kune "randomBoolean" chinja. The boolean value ichokwadi kana nhema, uye inogadzirwa neMath.random() basa. Iri basa rinodzosa nhamba isina kurongeka pakati pa 0 na 1, uye kana nhamba iyi yakakura kupfuura kana kuenzana na 0.5, ipapo kukosha kwe boolean kuchava kwechokwadi. Zvikasadaro, zvinenge zviri zvenhema.
Chii chinonzi kirasi
?
Kirasi muJavaScript template yekugadzira zvinhu.
Wedzera Makirasi
Kuwedzera makirasi chinhu cheJavaScript chinokutendera kuti ugadzire makirasi echivanhu anogona kushandiswa mukodhi yako. Izvi zvinogona kubatsira kana iwe uchida kugadzira yakasarudzika mhando kana kana iwe uchida kuwedzera chaiyo mashandiro kune iripo mhando.
Kuti ugadzire kirasi yekuwedzera muJavaScript, iwe unofanirwa kutanga wagadzira faira nyowani inonzi extend.js uye wowedzera inotevera kodhi:
var MyClass = function(){}; MyClass.prototype = {}; MyClass.extend = basa(zvimwe){this.prototype = other.prototype; };
Tevere, iwe unofanirwa kutsanangura zvivakwa uye nzira dzekirasi yako nyowani. Iwe unoita izvi nekuwedzera zvivakwa uye nzira kune MyClass chinhu prototype chinhu. Heino muenzaniso:
MyClass.prototype._myMethod = basa(){}; MyClass.prototype._anotherMethod = basa(){}; MyClass.extend({ _myMethod : function(){}, _anotherMethod : function(){}});
Chekupedzisira, unofanirwa kunyoresa kirasi yako nyowani neJavaScript compiler nekuwedzera mutsara unotevera kune yako kodhi:
MyClass._register = function(){};
