问题描述
我正在尝试遍历打字稿图，但是我一直遇到错误，而且对于这种琐碎的问题，我还找不到任何解决方案.
I'm trying to iterate over a typescript map but I keep getting errors and I could not find any solution yet for such a trivial problem.
我的代码是:
myMap : Map<string, boolean>;
for(let key of myMap.keys()) {
console.log(key);
}
我得到了错误:

Error: Typescript found the following errors:

我正在使用angular-cli beta5和打字稿1.8.10，我的目标是es5.有人遇到这个问题吗?
I'm using angular-cli beta5 and typescript 1.8.10 and my target is es5.Has anyone had this Problem?
推荐答案
您可以改用Map.prototype.forEach((value, key, map) => void, thisArg?) : void
像这样使用它:
myMap.forEach((value: boolean, key: string) => {
console.log(key, value);
});
