建造者模式（Builder Pattern）及应用场景 建造者模式是一种创建型设计模式，它允许你分步骤地构建复杂对象。这种模式特别适用于需要创建具有多个可选配置参数的对象，或者当对象的构造过程非常复杂时。在JavaScript中，建造者模式可以帮助我们更清晰地组织代码，提高代码的可读性和可维护性。下面我们将通过具体的例子来探讨...
1.首先要定义builder的接口 2.然后各个concretebuilder类去实现这个接口 3.director中接收一个builder实例作为参数,最后返回一个一类车的实例 示例代码 function Director() {this.construct = function (builder) { builder.step1(); builder.step2();returnbuilder.get(); } }//由于js不支持接口,我个人认为其实...

在鸿蒙系统中,UI 的构建主要通过 XML 布局文件和 Java/Kotlin(对于 HarmonyOS 应用开发来说,实际上是 Java/JavaScript/eTS - Extensible TypeScript)代码来实现。但是,为了回答你的问题,我可以提供一个基于“构建器模式”(Builder Pattern)的概念性示例,用于在代码中动态构建和传递 UI 组件的参数。 示例:使用构建器...
