1 00:00:00,420 --> 00:00:06,480 With Jake Query we can create Dragonball elements in this example you can see when we click and hold 2 00:00:06,510 --> 00:00:12,720 our mouse button down on the div element we can reposition it anywhere in the browser's content area 3 00:00:16,340 --> 00:00:20,240 in order to do this we'll be working with J query user interface. 4 00:00:20,600 --> 00:00:27,890 As per the J query Web Site J query UI is a widget and interaction library built on top of the J. 5 00:00:27,890 --> 00:00:35,280 Query javascript library it can be used to create highly interactive web applications. 6 00:00:35,370 --> 00:00:39,990 Let's take a look at the script to see how this effect was created. 7 00:00:40,110 --> 00:00:48,210 The first important thing to note is that we've included D.J. query dot UI dot J.S. 8 00:00:50,760 --> 00:00:55,650 script in our head take and this is in addition to our normal J query source script 9 00:00:58,580 --> 00:01:05,160 the UI script is required if you intend to use any of the J query UI interactions as we will be doing 10 00:01:05,160 --> 00:01:16,210 in this lesson next we've created a div element in our body take it did element I has the idea drag 11 00:01:17,660 --> 00:01:20,070 we've created a style sheet in our head take 12 00:01:22,900 --> 00:01:28,600 this defines the appearance of the drag div and you can see it has a with in height of one hundred and 13 00:01:28,600 --> 00:01:31,840 fifty pixels in the background color is blue 14 00:01:37,170 --> 00:01:45,490 our script starts with the document ready function we've also applied the Dragonball perimeter to the 15 00:01:45,490 --> 00:01:55,870 drag div as you can see here this is the perimeter that allows the div to be Dragonball the drag interaction 16 00:01:55,870 --> 00:02:02,380 is only recognized if the J query UI JavaScript file is referenced in the head dead 17 00:02:10,780 --> 00:02:11,540 and so that's all. 18 00:02:11,740 --> 00:02:16,450 That's all that's involved in creating this effect.
