How to display item of nested json array in component using Angular 7 – Photoshop

How can I display “empName” and other details of this JSON in my table component in loop?

I’m using a third party API which provides a nested JSON object in return when I send employerID to the API URL.

After subscribing I’m storing the response in a var “AllPostedJobs”

{
    "status": "All Jobs",
    "result": [
        {
            "_id": "5c90fd3cfc7f3b0017803319",
            "job_title": "Web Designer",

    You can bind display data by binding controls in an HTML template to properties of your component.

    The easiest way to display a component property is to bind the property name through interpolation. With interpolation, you put the property name in the view template, enclosed in double curly braces:{{AllPostedJobs.status}}.

    <div  id="result-container" *ngFor="let record of AllPostedJobs.result">
   <another-component [record]= "record"></another-component>
</div>

    Or depending on your need you can hand over entire result data to another-component.

    Now your another-component, should have @Input defined to handle the incoming data:

    export class AnotherComponent {
    @Input() record: Array<any>;

    In your another-component template:

    <div *ngFor="let student of record?.AppliedStudentDetails">
      <span>{{student.empName}}</span>
      <span [innerText]="student.job_title"></span>
    </div>

    The simplest way is when you receive data from api then send it to a
    function then apply multiples loop alter your data by add keys in
    front of data and that values for example

    var data = [{"id":1, "name":"smith","applicant":{"roll": 32,"class":10}}];
data[0].applicantRoll = data[0].applicant.roll;
data[0].applicantClass = data[0].applicant.class;

    now you can apply *ngfor easily, try this.
