我正在使用类似脚本创建一个类,该类具有ES6(ECMAscript 2016)Map的属性,如下所示:

class Item {
  configs: ????;
  constructor () {
    this.configs = new Map();
  }
}

如何在打字稿中声明ES6 Map类型？

如何将这些类序列化为JSON？

从下面的示例中可以看出,JSON.stringify()没有序列化对象Cache_Backend_LocalStorage_Tag内部的列表Cache_Backend_LocalStorage_TagThree.

我错过了什么？

interface Cache_Backend_LocalStorage_Tag_Interface {
    _tag : string;
    _keys : string[];
}

class Cache_Backend_LocalStorage_Tag implements Cache_Backend_LocalStorage_Tag_Interface {

    public _tag : string;
    public _keys : string[];

    constructor(tag : string) {
        this._tag = tag;

        this._keys = [];
    }

    public add(key : string) : void {
        this._keys.push(key);   
    }

    public remove(key : string): boolean {
        // Get the index of the key
        var index = this._keys.indexOf(key, 0);

        // Check if we found the keys index
        if (index …

我在c#中有字典对象.但我需要迁移到打字稿.我是打字稿的新手.我真的不知道,如何在打字稿中使用字典.

C#:

 LengthsByCountry = new Dictionary<string, int>
            {
                {"AD", 24}, {"AL", 28}, {"AT", 20}, {"BA", 20}, 
                {"BE", 16}, {"BG", 22}, {"CH", 21}, {"CY", 28}, 
                {"CZ", 24}, {"DE", 22}, {"DK", 18}, {"EE", 20}, 
                {"ES", 24}, {"FI", 18}, {"FO", 18}, {"FR", 27}, 
                {"GB", 22}, {"GE", 22}, {"GI", 23}, {"GL", 18}, 
                {"GR", 27}, {"HR", 21}, {"HU", 28}, {"IE", 22}, 
                {"IL", 23}, {"IS", 26}, {"IT", 27}, {"LB", 28}, 
                {"LI", 21}, {"LT", 20}, {"LU", 20}, {"LV", 21}, 
                {"MC", 27}, {"ME", 22}, {"MK", 19}, {"MT", 31}, …

我想为这样的json结构声明一个TypeScript接口:

{ 
404: function() { alert( "page not found" ); }, 
400 : function() {...} 
}

键是数字,值是函数,你知道如何在TypeScript中声明这样的数据约束的接口吗？

是否可以在angular 2 Map <String,List <String >>中创建？
