How do I declare a public enum in typescript?
提问by David Thielen
For the following class:
对于以下课程：
module LayoutEngine {
enum DocumentFormat {
DOCX = 1
};
export class DocHeader {
public format : DocumentFormat;
}
}
I have two questions:
我有两个问题：
- The above has a compile error where it says "Public property 'format' of exported class has or is using private type 'DocumentFormat'." but a declaration of public before the enum is also an error. So how do I do this?
- Is there a way to place the enum declaration inside the class? Just a module name isn't great for namespacing as I have a lot of classes in that module.
- 上面有一个编译错误，它说“导出类的公共属性‘格式’具有或正在使用私有类型‘文档格式’。” 但是在枚举之前声明 public 也是一个错误。那么我该怎么做呢？
- 有没有办法将枚举声明放在类中？仅仅一个模块名称并不适合命名空间，因为我在该模块中有很多类。

上面有一个编译错误，它说“导出类的公共属性‘格式’具有或正在使用私有类型‘文档格式’。
Simply export :
只需导出：
module LayoutEngine {
export enum DocumentFormat {
DOCX = 1
};
export class DocHeader {
public format : DocumentFormat;
}
}
Is there a way to place the enum declaration inside the class?
有没有办法将枚举声明放在类中？
the enumtypescript type needs to be at a module level (a file or inside a module). Of course if you want it inside the class just use a json object
所述enum打字稿类型需要处于一个模块级（文件或模块内）。当然，如果您想在类中使用它，只需使用 json 对象
module LayoutEngine {
export class DocHeader {
DocumentFormat = {
DOCX: 1
};
public format : number;
}
}
