Creating The Interface

This is where we will create a simple interface for our application. This code will only display the html form and button. To create this simply copy and write it into your text editor, then save it as index.html.
  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
  6. </head>
  7. <nav class="navbar navbar-default">
  8. <div class="container-fluid">
  9. <a class="navbar-brand" href="">Sourcecodester</a>
  10. </div>
  11. </nav>
  12. <div class="col-md-3"></div>
  13. <div class="col-md-6 well">
  14. <h3 class="text-primary">How to Dynamically Add new Textbox using jQuery</h3>
  15. <hr style="border-top:1px dotted;"/>
  16. <div class="col-md-4">
  17. <form>
  18. <div class="form-group">
  19. <input type="text" id="input" class="form-control"/>
  20. </div>
  21. <button type="button" id="add" class="btn btn-primary">Add Input</button>
  22. <br /><br />
  23. <div id="input_container"></div>
  24. <button type="button" style="display:none;" id="submit" class="btn btn-success">Submit</button>
  25. </form>
  26. </div>
  27. </div>
  28. <script src="js/jquery-3.2.1.min.js"></script>
  29. <script src="script.js"></script>
  30. </body>
  31. </html>

Creating JavaScript Function

This is where the main function of the application is. This code will add new textbox dynamically when the buttons is clicked. To do this just copy and write these block of codes inside the text editor and save it as script.js.
  1. $(document).ready(function(){
  2. $('#add').on('click',function(){
  3. var input = $('#input').val();
  4. if(input != ""){
  5. $('#submit').show();
  6. var newInput = $(
  7. '<div class="form-group">'
  8. +'<input type="text" placeholder="'+input+'" class="form-control newInput" required="required"/>'
  9. +'</div>'
  10. );
  11. newInput.appendTo('#input_container');
  12. $('#input').val('');
  13. }else{
  14. alert("Please enter something");
  15. }
  16. });
  18. $('#submit').on('click', function(){
  19. var list=[];
  20. $('.newInput').each(function(){
  21. list.push($(this).val());
  22. });
  24. alert(list.join(', '));
  25. });
  26. });

In the given code we first call the basic jQuery ready event to signal that the DOM of the page is now ready to be use. In this code we just simply bind the button to trigger the event for adding new textbox. The function includes some variables and a certain function that will add new textbox using the append function of jQuery.
