遍历 typescript 中的嵌套 JSON 字符串

Question

I have a test nested JSON string.

const testString = `{
  "object1": {
    "5": [
      {
        "id": "A2OKPZ5S9F78PD",
        "rate": "2",
        "item": "item",
        "status": "status"
      }
    ]
  },
  "type": "LIVE_EVENT"
}`;

const model = JSON.parse(testString);
Object.values(model.object1).forEach((obj) =>
  obj.foreach((innerObj) => console.log(innerObj))
);

As you can see above I am trying to parse this as JSON and iterate over. The problem which I am facing during JSON.parse the inner object assumes the type undefined and foreach can not be applied on it. Can some one please help?

Your JSON is was invalid (before an edit) due to an extra comma after the status key/value pair and forEach() has an uppercase E. Also, as discussed in the comments below it seems you need to cast the inner obj to be of a type that understands forEach() :

 const testString = `{"object1":{"5":[{"id":"A2OKPZ5S9F78PD","rate":"2","item":"item","status":"status"}]},"type":"LIVE_EVENT"}`; const model = JSON.parse(testString); Object.values(model.object1).forEach((obj) => (obj as any).forEach((innerObj) => console.log(innerObj)) );
