TypeScript，通过字典循环 [英] TypeScript, Looping through a dictionary

问题描述

在我的代码中，我有几个字典（正如建议这里），它是String索引的。由于这是一种即兴类型，我想知道是否有任何关于如何能够遍历每个键（或值，我需要键的所有内容）的建议。任何帮助赞赏！

  myDictionary：{[index：string]：any; } = {}; 
  

解决方案

要循环使用键/值， code $ for循环：

$ p $ for（let key in myDictionary）{
let value = myDictionary [key];
//使用`key`和`value`
}


In my code, I have a couple of dictionaries (as suggested here) which is String indexed. Due to this being a bit of an improvised type, I was wondering if there any suggestions on how I would be able to loop through each key (or value, all I need the keys for anyway). Any help appreciated!

myDictionary: { [index: string]: any; } = {};

解决方案

To loop over the key/values, use a for in loop:

for (let key in myDictionary) {
    let value = myDictionary[key];
    // Use `key` and `value`
}
