摘要： function P() {};P.prototype.show = function() {};function C() {};C.uber = function() {};function I(C,P){ var F = function() {}; F.prototype = P.prototype; C.prototype = new F(); C.uber =P.prototype; };I(C,P);var k = new C();绕丫绕！ 阅读全文

摘要： var C = (function() { var count = 0; return function() { return (count++); }}());var c1 = new C(); //0--count的值var c2 = new C(); //1var c3 = new C(); //2var D= function() { var count = 0; return count++;};var d1 = new D(); //0 --count的值var d2 = new D(); //0var d3 = new D(); //0这个问题是闭包closure原因造成的，但是 阅读全文
