**value **数据结构约定:value值部分约定text为文本描述,type为样式类别(elementUI中的状态type:success/info/warning/danger),其他可随意。 参数keyParseFunc为key的转换函数,默认key为字符串,keyParseFunc默认值为null(不转换),如果key为整数,则需要传入转换函数(传入JS内置parseInt即可)。 返回值继承自参数enumObj,...
设计一个枚举工厂 EnumFactory(enumFactory.js),统一创建枚举所需的属性和方法: 参数enumObj为要传入的枚举基础定义:标准模式(key:{text:'',type:''})示例:{ 1: { text: '男', type: 'priary' }, 2: { text: '女', type: 'warning' }}简写模式(key:text),会被自动转换为标准模式,示例:{ left...
letvalues = [], texts = [], entries = []; constvobjs =Object.values(enumObj); if(typeofvobjs[0] ==='string') { texts = vobjs; vobjs.forEach((item, index) =>{ entries.push({key:this.keys[index],text: texts[index] }); }) } else{ vobjs.forEach((item, index) =>{ t...
Enums or enumerations are a new data type supported in TypeScript. Most object-oriented languages like Java and C# use enums. This is now available in TypeScript too. In simple words, enums allow us to declare a set of named constants i.e. a collection of related values that can be...

This is useful for building data structures, for enumerating all assigned code points, etc. For each contiguous range of code points with a given general category ("character type"), the callback function is called. Adjacent ranges have different types. The Unicode Standard guarantees that the...
In TypeScript, it is common to need to convert between enums and string values, particularly when working with external data sources like databases or APIs, where data is usually serialized as strings. Because string enums naturally map to string values, converting an enum to a string is simp...
Only a constructor function can have the same name as the class it appears in. MustImplementMethod 1128 The class must provide an implementation of the method.
