如何从angular的json文本中提取类名及其属性？

Question

I am new to angular and my internship demands dealing with a lot of json texts and files. The json i'm currently working on looks like this (it represents a class) :

{
  "name": "client",
  "properties": {
    "firstName": "string",
    "lastName": "string",
    "cin": "string",
    "age": "int"
  }
}

the angular project reads the json text from a textarea therefore the name and the properties can change.

I need to extract the name of the class and its attributes separetly each time i hit the submit button .

        <form  #json="ngForm" >
            <textarea placeholder="paste your json file in here" rows="15" cols="150"></textarea>
            <button (click)='sendJson(json)'> submit </button>
        </form>

Can anyone help me please ?

Hey I'm not entirely sure what your asking but you can simply use and [(ngModel)] to track the changes made and save it to a variable.

.TS

jsonChanges: string;

HTML

<textarea [(ngModel)]="jsonChanges" placeholder="paste your json file in here" rows="15" cols="150"></textarea>
