I cannot apply js color set (jscolor.js) in input field

Below is the html code of the code code

   <head>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
     <script src="jscolor-2.0.4/jscolor.js"></script>
      <body>

        <script>
      $(document).ready(function() {
      var max_fields      = 10; 
       var wrapper         = $(".input_fields_wrap");
          var add_button      = $(".add_field_button"); 

       var x = 1; 
         $(add_button).click(function(e){ 
         e.preventDefault();
          if(x < max_fields){ 
        x++; 
        $(wrapper).append('<div>Case :<input type="text" name="mytext"> Color Picker :  <input class="jscolor" name="c_picker"><br><a href="#" class="remove_field">Remove</a></div>');
    }
});

$(wrapper).on("click",".remove_field", function(e){ 
    e.preventDefault(); $(this).parent('div').remove(); x--;
})
  });
  </script>


        <form>
    DB-URl  :
    <input type="text" name="firstname"><br/>
      Username:
    <input type="text" name="lastname"><br/>
    Password:
   <input type="password" name="Password"><br>
    Table Name:
    <input type="text" name="t_name"><br>
    Color column:
   <input type="text" name="c_column"><br>
  <div class="input_fields_wrap">
    <button class="add_field_button">Add More Fields</button>
    <div>Case :<input type="text" name="mytext">  Color Picker :  <input  class="jscolor" name="c_picker"><br></div>
      </div>
   <input type="submit" value="Update" id="updating">  
 </form>

The first js color selection is applied in the input field, but when I add more color selection field, dynamic js color selection is not applied in the next input field. Can someone explain to me why this is happening?

Use jscolor()to the bindnewly added item:

    $(document).ready(function () {
                var max_fields = 10;
                var wrapper = $(".input_fields_wrap");
                var add_button = $(".add_field_button");

                var x = 1;
                $(add_button).click(function (e) {
                    e.preventDefault();
                    if (x < max_fields) {
                        x++;
                        $(wrapper).append('<div>Case :<input type="text" name="mytext">Color Picker : <input class="jscolor" name="c_picker"><br><a href="#" class="remove_field">Remove</a></div>');
                        var color = new jscolor($(wrapper).find('input.jscolor:last')[0]);
                        //$(wrapper).find('input.jscolor:last').each(function () {
                            //var color = new jscolor($(this)[0]);

                    //});


                    }
                });

                $(wrapper).on("click", ".remove_field", function (e) {
                    e.preventDefault();
                    $(this).parent('div').remove(); x--;
                });
            });

You can initialize jsColor on the added input using:

new jscolor($('.jscolor').last()[0]);

NOTE: You do not have to go through all the inputs.

$(document).ready(function() {
  $('.add_field_button').click(function(e){
    e.preventDefault();

    $('form').append('<div>Case :<input type="text" name="mytext">        Color Picker :  <input class="jscolor" name="c_picker"><br><a href="#" class="remove_field">Remove</a></div>');

    new jscolor($('.jscolor').last()[0]);
  });
});

<form>
  <div class="input_fields_wrap">
    <button class="add_field_button">Add More Fields</button>
    <br><br>
    <div>Case :<input type="text" name="mytext">  Color Picker :  <input  class="jscolor" name="c_picker"><br></div>
  </div>  
</form>

If you insert a new HTML element after loading the document, you will need to assign a unique identifier to each new element and attach it manually using this code:

$("#idOfNewElement").colorpicker();

This is solved in this stackoverflow question:
using jscolor.js for dynamic input

The solution was to add:

$(document).ready(function() {
  jscolor.installByClassName("jscolor");
});
