As noted above in the code comments, the act of settinggk.raceto some value did NOT overwrite the privateracevariable. Although it would be a dumb idea, you can have both private and public variables with the s
它可以使用:this.特权函数() 方式来调用特权函数,使用 :私有函数()方式来调用私有函数。 公共属性通过this.variableName来定义而且在对象外部是可以读写的。不能被私有函数所调用。 公共方法通过ClassName.prototype.methodName=function(){...}来定义而且可以从对象外部来调用。 原型属性通过ClassName.prototype.property...
Private Members in JavaScript 在该文章中指出,在对象内部使用 var 创建的变量属于私有变量、这个是外部无法访问的。 在这里var的变量我们换一种说法就是局部变量。...事实上不能算是真正的私有属性。我们知道在面向对象编程中,一个类的属性、方法如果能够被其他类访问
gk.showLegs(); lk.showLegs(); //Both share the common 'Person.prototype.legs' variable when looking at 'this.legs' gk.race = "hispanic"; //Sets a public variable, but does not overwrite private 'race' variable. alert(gk+"'s real race is "+gk.getRace()); //Returns 'caucasian' ...
Person = function(name,sex){ this.name = name; this.sex = sex; var _privateVariable = ...
公共属性通过this.variableName来定义而且在对象外部是可以读写的。不能被私有函数所调用。 公共方法通过ClassName.prototype.methodName=function(){...}来定义而且可以从对象外部来调用。 原型属性通过ClassName.prototype.propertyName=someValue来定义。 静态属性通过ClassName.propertyName=someValue来定义。

In JavaScript, developers often hide a lot more than just “methods”. Modules, classes, and even entire programs can all be private. In fact, it’s not uncommon to see a library that doesn’t expose a single global variable. Due to the nature of the browser environment, code is kept ...
