classUser{constructor(name){this.name=name;}} User的构造函数有一个参数name,用于设置字段this.name的初始值 在构造函数中,this值等于新创建的实例。用于实例化类的参数成为构造函数的参数: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 classUser{constructor(name){name;// => '前端小智'this.name=n...
但是,如果我们试图在 User 主体之外访问私有字段#name,则会抛出一个语法错误:SyntaxError: Private field '#name' must be declared in an enclosing class。 3.3 公共静态字段 我们还可以在类本身上定义字段:静态字段。这有助于定义类常量或存储特定于该类...
name;// => '前端小智'this.name= name; } }constuser =newUser('前端小智'); 构造函数中的name参数的值为'前端小智'。如果没有定义该类的构造函数,则会创建一个默认的构造函数。默认的构造函数是一个空函数,它不修改实例。 同时,一个JavaScript 类最多可以有一个构造函数。
类语法不会为JavaScript引入新的面向对象的继承模型。 class类概念与语法 ES5之前不存在类的概念,创建对象使用的构造函数,通过new操作符来创建; 为使JS更像面向对象,ES6版本引入class概念,其基本语法: class Cat{ constructor(name,age){ this.name = name; ...

Theclassattribute is often used to point to a class name in a style sheet. It can also be used by a JavaScript to access and manipulate elements with the specific class name. In the following example we have threeelements with aclassattribute with the value of "city". All of the three...
