bootstrap中有javascript插件modal也就是对话框，加入拖拽功能，具体内容如下

在使用modal时首选需要引用js

<link href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.css" rel="stylesheet">
<script src="//cdn.bootcss.com/jquery/2.1.4/jquery.js"></script>
<script src="//cdn.bootcss.com/jqueryui/1.11.4/jquery-ui.js"></script> // 完成拖拽功能
<script src="//cdn.bootcss.com/bootstrap/3.3.5/js/bootstrap.js"></script> // 完成Modal

编辑Html代码

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>BootStrap Modal</title>
 <link href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.css" rel="external nofollow" rel="external nofollow" rel="stylesheet">
 <script src="//cdn.bootcss.com/jquery/2.1.4/jquery.js"></script>
 <script src="//cdn.bootcss.com/jqueryui/1.11.4/jquery-ui.js"></script>
 <script src="//cdn.bootcss.com/bootstrap/3.3.5/js/bootstrap.js"></script>
</head>
<body>
 <button class="btn btn-default">显示Modal</button>
 
 <div class="modal fade">
 <div class="modal-dialog">
 <div class="modal-content">
 <div class="modal-header">
 <button type="button" class="close" data-dismiss="modal" aria-label="Close">
 <span aria-hidden="true">&times;</span>
 </button>
 <h4 class="modal-title">Modal title</h4>
 </div>
 <div class="modal-body">
 <p>One fine body&hellip;</p>
 </div>
 <div class="modal-footer">
 <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
 <button type="button" class="btn btn-primary">Save changes</button>
 </div>
 </div>
 <!-- /.modal-content --> 
 </div>
 <!-- /.modal-dialog --> 
 </div>
 <!-- /.modal -->
<script type="text/javascript">
 var $button = $('.btn-default'),
 $modal = $('#myModal');
 $(function(){
 $button.on('click',function(event) {
 event.preventDefault();
 /* Act on the event */
 $modal.show(
 '500',
 function() {
 var modal = $(this);
 modal.find('.modal-title').text('New message to ');
 $.ajax({});
 });
 $modal.modal('show');
 });
 });
 </script>
 
</body>
</html>

要完成拖拽功能需要修改一下javascript

<script type="text/javascript">
 var $button = $('.btn-default'),
 $modal = $('#myModal');
 $(function(){
 $button.on('click',function(event) {
 event.preventDefault();
 /* Act on the event */
 $modal.show(
 '500',
 function() {
 var modal = $(this);
 modal.find('.modal-title').text('New message to ');
 $.ajax({});
 });
 /* 完成拖拽 */
 $modal.draggable({
 cursor: "move",
 handle: '.modal-header'
 });
 $modal.modal('show');
 });
});
</script>
