As of TypeScript 2.4, it is now possible to define string enums, or more precisely, enums with string members. Just like any other numeric enum, string enums can be made constant using theconstmodifier so that they disappear entirely from the generated JavaScript; in this case, all enum ...
typescript enum Color { Red, Green, Blue } 字符串到枚举的转换:使用枚举的反向映射特性,可以通过枚举类型名加上方括号和字符串值来访问对应的枚举成员。 typescript function stringToEnum(enumType: any, enumString: string): any { return enumType[enumString]; } const colorString = "Green"; const...
在TypeScript中,可以使用枚举的[枚举名][字符串]语法来获取对应的枚举成员。下面是一个简单的示例: enumDirection{Up,Down,Left,Right,}functiongetDirectionFromString(str:string):Direction{returnDirection[str];}constdirection=getDirectionFromString("Up");console.log(direction);// 输出:0 1. 2. 3. 4. ...
