How to dynamically create these HTML elements using JS

enter image description here I want to create this layout, dynamically to create a list of it, getting the data from database and populate.

Here's the layout's code:

<div class="card-body">
  <!-- person -->
  <div class="row" id="img_div">
    <div class="col-12 col-sm-12 col-md-2 text-center">
      <img src="http://placehold.it/120x80" alt="prewiew" width="120" height="80">
    </div>
    <div id="text_div" class="col-12 text-sm-center col-sm-12 text-md-left col-md-6">
      <h4 class="product-name"><strong>Person Name</strong></h4>
      <h4>
        <small>state</small>
      </h4>
      <h4>
        <small>city</small>
      </h4>
      <h4>
        <small>zip</small>
      </h4>
    </div>
    <div class="col-12 col-sm-12 text-sm-center col-md-4 text-md-right row">


    </div>
  </div>
  <!-- END person -->
  <!-- person -->
  <div class="row" id="img_div">
    <div class="col-12 col-sm-12 col-md-2 text-center">
      <img src="http://placehold.it/120x80" alt="prewiew" width="120" height="80">
    </div>
    <div id="text_div" class="col-12 text-sm-center col-sm-12 text-md-left col-md-6">
      <h4 class="product-name"><strong>Person Name</strong></h4>
      <h4>
        <small>state</small>
      </h4>
      <h4>
        <small>city</small>
      </h4>
      <h4>
        <small>zip</small>
      </h4>
    </div>
    <div class="col-12 col-sm-12 text-sm-center col-md-4 text-md-right row">

    </div>
  </div>
  <!-- END person -->
</div>

For recap, I want to replicate the "person" layout dynamically to populate with database data

Is there any library of Javascript that can do the job?

If your data is an array of objects, you can iterate through it to generate the HTML before inserting into the DOM.*

Here I've used a helper function to generate the HTML of each individual person card (personCardHtml). It returns a template literal which fills in the person's details in the correct spot within the HTML.

I've used Array.reduce on the array of people to generate a single string of HTML of all the person cards together.

Then I've used insertAdjacentHTML to insert that html string into <div id="persons-container"></div>

const people = [{"name": "Henrietta Marsh","state": "Northern Mariana Islands","city": "Ernstville","zip": 7226},{"name": "Sandy Copeland","state": "Wyoming","city": "Hobucken","zip": 4594},{"name": "Logan Frank","state": "Puerto Rico","city": "Talpa","zip": 8670}]

const personCardHtml = (person) => {
  return `<div class="card-body">
  <!-- person -->
  <div class="row" id="img_div">
    <div class="col-12 col-sm-12 col-md-2 text-center"><img src="http://placehold.it/120x80?text=${person.name}" alt="prewiew" width="120" height="80"></div>
    <div id="text_div" class="col-12 text-sm-center col-sm-12 text-md-left col-md-6">
      <h4 class="product-name"><strong>${person.name}</strong></h4>
      <h4><small>${person.state}</small></h4>
      <h4><small>${person.city}</small></h4>
      <h4><small>${person.zip}</small></h4>
    </div>
  </div>
  <!-- END person -->`
}
const reducer = (accumulator, currentValue) => accumulator + personCardHtml(currentValue);
const personsHtml = people.reduce(reducer, '')
const container = document.querySelector('#persons-container')
container.insertAdjacentHTML('beforeend', personsHtml);
<div id="persons-container"></div>

* It is best practice to keep DOM manipulations to a minimum if you want your page to be performant.

You can use template literals in js to solve your issue.

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width" />
    <title>JS Bin</title>
  </head>
  <body>
    <div id="root"></div>
    <script>
      let root = document.getElementById("root");
      const persons = [
        {
          name: "person1",
          state: "person1_state",
          city: "person1_city",
          zip: "person1_zip"
        },
        {
          name: "person2",
          state: "person2_state",
          city: "person2_city",
          zip: "person2_zip"
        },
        {
          name: "person3",
          state: "person3_state",
          city: "person3_city",
          zip: "person3_zip"
        },
        {
          name: "person4",
          state: "person4_state",
          city: "person4_city",
          zip: "person4_zip"
        }
      ];

      const renderPerson = persons => {
        let data = ``;
        persons.forEach(person => {
          data += `
            <div class="card-body">
                <!-- person -->
                <div class="row" id="img_div">
                    <div class="col-12 col-sm-12 col-md-2 text-center">

                    <div id="text_div" class="col-12 text-sm-center col-sm-12 text-md-left col-md-6">
                        <h4 class="product-name"><strong>${person.name}</strong></h4>
                        <h4>
                            <small>${person.state}</small>
                        </h4>
                        <h4>
                            <small>${person.city}</small>

                        <h4>
                            <small>${person.zip}</small>
                        </h4>
                    </div>
                <div class="col-12 col-sm-12 text-sm-center col-md-4 text-md-right row">


                    </div>
                </div>
                <!-- END person -->
            </div>`;
        });
        return data;
      };
      
      
      
      root.innerHTML = renderPerson(persons);
      
      
      
    </script>
  </body>
</html>

With pure javascript you can do this. Demo: https://codepen.io/ftj07/pen/KKppeaL

 <div class="row" id="designId"><div>

  <input type="button" onClick="generateList()" value="generateList" /> 
function generateList() {
  var personList = [
     { name: "Abc", state: "41", city: "USA", zip: "124" },
     { name: "Abc", state: "41", city: "USA", zip: "124" },
     { name: "Abc", state: "41", city: "USA", zip: "124" },
     { name: "Abc", state: "41", city: "USA", zip: "124" },
     { name: "Abc", state: "41", city: "USA", zip: "124" }
  ]
  let design = "";
  for(let item of personList){
    design += `
  <div class="col-12 col-sm-12 col-md-2 text-center">
   <img src="http://placehold.it/120x80" alt="prewiew" width="120" height="80">
  </div>
  <div id="text_div" class="col-12 text-sm-center col-sm-12 text-md-left col-md-6">
   <h4 class="product-name"><strong>${item.name}</strong></h4>
   <h4>
    <small>${item.state}</small>
   </h4>
   <h4>
    <small>${item.city}</small>
   </h4>
   <h4>
    <small>${item.zip}</small>
   </h4>
  </div>  `
  }
  console.log("da",design)
  document.getElementById("designId").innerHTML  = design;
}

Use the following code for creating dynamic element and add attribute to that element.

<!DOCTYPE html>
<html>
<head>
<style>
#myDIV {
  border: 1px solid black;
  margin-bottom: 10px;
}
</style>
</head>
<body>

<p>Click the button to create a P element with some text, and append it to DIV.</p>

<div id="myDIV">
A DIV element
</div>

<button onclick="myFunction()">Try it</button>

<script>
function myFunction() {
  var para = document.createElement("P");
  para.innerHTML = "This is a paragraph.";
  document.getElementById("myDIV").appendChild(para);
}
</script>

</body>
</html>

I Will generate design the same as you mention in the above image. add CSS in your file. dynamically javascript creates multiple data.

$(document).ready(function(){
  
  for(i=0;i<10;i++){
  $("#allPerson").append(`<div class="row" id="img_div">
    <div class="col-12 col-sm-12 col-md-2 text-center person">
      <img src="http://placehold.it/120x80" alt="prewiew" width="120" height="80">
    </div>
    <div id="text_div" class="col-12 text-sm-center col-sm-12 text-md-left col-md-6 div">
      <h4 class="product-name"><strong>Person Name</strong></h4>
      <h4>
        <small>state</small>
      </h4>
      <h4>
        <small>city</small>
      </h4>
      <h4>
        <small>zip</small>
      </h4>
    </div>
    <div class="col-12 col-sm-12 text-sm-center col-md-4 text-md-right row">
  </div>
  </div>`);
  }
  
});
.person{
  float:left;
  margin-right:10px;
}
#img_div{
  width:100%;
  margin:10px;
  float:left;
}
h4{
  margin:0;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>
<div class="card-body" id="allPerson">
  <!-- person -->

  <!-- END person -->
  <!-- person -->

  <!-- END person -->
  
</div>

You can use a for loop to append the HTML to the element of your choice. The i in the loop is the size of the elements received from the database

for(let i=1;i<10;i++)
{
document.querySelector('.card-body').innerHTML+=`<div class="row" id="img_div">
    <div class="col-12 col-sm-12 col-md-2 text-center">
      <img src="http://placehold.it/120x80" alt="prewiew" width="120" height="80">
    </div>
    <div id="text_div" class="col-12 text-sm-center col-sm-12 text-md-left col-md-6">
      <h4 class="product-name"><strong>Person`+i+`</strong></h4>
      <h4>
        <small>state</small>
      </h4>
      <h4>
        <small>city</small>
      </h4>
      <h4>
        <small>zip</small>
      </h4>
    </div>
    <div class="col-12 col-sm-12 text-sm-center col-md-4 text-md-right row">
    </div>
  </div>
 `
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
<div class="card-body">
  <!-- person -->
  </div>
