Sweet Alert JS library - beautiful replacement of JavaScript Alert

You may think JS alert is boring and less flexible. You can use Sweet Alert. You can download and see the demo of sweet alert from:
Then initialize the plugin by referencing the necessary files (js and css):
<script src="sweetalert.min.js"></script>
<link rel="stylesheet" type="text/css" href="sweetalert.css">
Example 1: error message:
sweetAlert("Not Allowed", "Average of Chair's Recommended Step  exceeds 1.25!", "error"); 

Example 2: error message:
                            title:" Are you sure?",
                            text:"You will not be able to edit.",
                            confirmButtonClass: "btn-danger",
                            confirmButtonText: "Yes, Submit & Lock",
                            confirmButtonColor: "#DD6B55",
                            cancelButtonText: "Cancel",
                            closeOnConfirm: true,
                            if(response == true){

Bootstrap Datepicker on change firing 3 times

I used Bootstrap Datepicker in js and it fires three times in post
               format: "yyyy-mm-dd",
                autoclose: true

       $('.date-picker').change(function() {
                         var row = $(this).parent().parent();
                         var stakeholder_id =row.find(".sid").val();
                         var salutation =  $(this).val();
                         var postdata = {stakeholder_id:stakeholder_id,salutation:salutation};
                         var url = '/tracs/ajax/salaryReview_chair_ajax/update_salaryreviewchair';
                         $.post(url, postdata, function(data) {
                                 $("div#notice").html('Salutation is updated.');
                                 $("div#notice").css('display', 'block');

bootstrap-datepicker.js needs to be fixed, the new version can be found:
or used

If you still used old bootstrap-datepicker.js, you can use
var datePicker = $('.date-picker').datePicker().on('changeDate', function(ev) {
    //Functionality to be called whenever the date is changed
var c=0;var send=false;
    $(document).ready(function() {
        jQuery( ".ed" ).datepicker({ 
            format: "yyyy-mm-dd",
        }).on('change',function() {

Make bootstrap Modal dialog draggable, move up and change header/footer style

I have Modal code:

<!-- Universal Modal -->
<div class="modal fade" id="universalModal"  style="margin-top:-150px;" tabindex="-1" role="dialog" aria-labelledby="universalModalLabel" aria-hidden="true">
  <div class="modal-dialog" style="width:1000px;">                                    
    <div class="modal-content">
      <form role="form" id="universalModalForm">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only"> Close</span></button>
          <h4 class="modal-title" id="universalModalLabel"><span class="glyphicon glyphicon-pencil"></span> Edit<span class="modal-title">.model-title</span></h4>
        <div class="alert alert-danger fade in" id="universalModal-alert" style="display: none;">
          <span class="alert-body"></span>
        <div class="modal-body">.modal-body</div>
        <div class="modal-footer">
          <input type="hidden" id='stakeholder_id' name='stakeholder_id'>
          <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
          <button type="submit" class="btn btn-primary" id="submitBtn"></button>

<!-- End Universal Modal -->
 1) To move  bootstrap Modal dialog up, I used style="margin-top:-150px;" for my id in top div including modal class.
2) To make   bootstrap Modal dialog draggable via modal header, body and footer
                $('#universalModal .modal-dialog').draggable({
                  handle: ".modal-header, .modal-body, .modal-footer"

3) To change header and footer style
  .modal-header  {
      background-color: #5cb85c;
      color:white !important;
      text-align: center;
      font-size: 20px;
  .modal-footer {
      background-color: #5cb85c;;
