How do I add textboxes dynamically in Javascript?

By default I have 5 textboxes. When a user clicks on a button, one textbox should be added.

How could I do this?

The best I can help is with this code
<html>
  <head>
  </head>
    <body>
      <input type=text id="chat" placeholder="Enter a message..." maxlength="120">
      <input type=Button id="Button" value="Test" onClick="T()">
      <h1 id="message"></h1>

    <script>
    function T() {
      var m = document.getElementById("chat").value
      document.getElementById("message").innerHTML = m
    }
    </script>
    </body>
</html>

by change for loop values we can generate textboxes dynamically 

function addFunction() {
  var table = document.getElementById("textbox");
  var rowlen = table.rows.length;
  var row = table.insertRow(rowlen);
  row.id = rowlen;
  var arr = ['textboxfiledname'];
  for (i = 0; i < 2; i++) {
    var x = row.insertCell(i)
    if (i == 1) {
      x.innerHTML = "<input type='button' onclick='removeCell(" + row.id + ")' value=Delete>"
    } else {
      x.innerHTML = "<label>" + arr[i] + ":</label><input type='textbox' name='" + arr[i] + "'>"
    }
  }
}

function removeCell(rowid) {
  var table = document.getElementById(rowid).remove();
}
input[type=text] {
  width: 100%;
  height: 50%;
  padding: 15px;
  border: 1px solid #ccc;
  border-radius: 4px;
  resize: vertical;
}

label {
  padding: 12px 12px 12px 0;
  display: inline-block;
  font-family: sans-serif;
}

input[type=button] {
  background-color: #4CAF50;
  border: none;
  color: white;
  padding: 6px 20px;
  text-decoration: none;
  margin: 4px 2px;
  cursor: pointer;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<fieldset style="margin-left:20%;margin-right:20%;font-family:sans-serif;padding:15px;border-radius:5px;background:#f2f2f2;border:5px solid #1F497D">
  <legend style="background:#1F497D;color:#fff;padding:5px 10px;font-size:22px;border-radius:5px;margin-left:20px;box-shadow:0 0 0 5px #ddd">DynamicTextbox</legend>
  <table id="textbox">
    <tr>
      <td>
        <input type="button" onclick="addFunction()" value="AddTextbox" />
      </td>
    </tr>
  </table>
</fieldset>

Javascript Function 

function add() {

//Create an input type dynamically.
var element = document.createElement("input");

//Create Labels
var label = document.createElement("Label");
label.innerHTML = "New Label";     

//Assign different attributes to the element.
element.setAttribute("type", "text");
element.setAttribute("value", "");
element.setAttribute("name", "Test Name");
element.setAttribute("style", "width:200px");

label.setAttribute("style", "font-weight:normal");

// 'foobar' is the div id, where new fields are to be added
var foo = document.getElementById("fooBar");

//Append the element in page (in span).
foo.appendChild(label);
foo.appendChild(element);
}

Html part,

<button id="button" value="Add" onClick:"javascript:add();">

And, Its done!

If you replace the innerHTML, the previously entered values will be cleared, to avoid that, you can append the input elements programmatically:

var input = document.createElement('input'); 
input.type = "text"; 
//...    
container.appendChild(input);

Check this example.

Best would be to attach an event on to the onclick of the button, that will set a div's visibility to inline. This is about the best way I can see for this, considering flexibility and robustness.

Have a look here for example code.
