Building `Drag-and-Drop` DIVs: Developing a Basic Script

Conventional pop-up windows in JavaScript applications may work for some things, but they can be annoying, and many people use pop-up blockers. There is an alternative: drag-and-drop DIV elements. In this article, Alejandro Gervasio gets you started with the basics.

Building `Drag-and-Drop` DIVs: Developing a Basic Script - Gluing the pieces together: defining the complete DIV dragging script
(Page 5 of 5 )

As I mentioned earlier, here is the complete DIV dragging script, along with some sample “drag-and-drop” DIVs:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script language="javascript">
// start dragging
function startDrag(e){
 // determine event object
 if(!e){var e=window.event};
 // determine target element
 var targ=e.target?e.target:e.srcElement;
 // calculate event X,Y coordinates
 // assign default values for top and left properties
 // calculate integer values for top and left properties
 // move div element
// continue dragging
function dragDiv(e){
 if(!e){var e=window.event};
 var targ=e.target?e.target:e.srcElement;
 // move div element
   return false;
// stop dragging
function stopDrag(){
<style type="text/css">
.draggable {
 position: relative;
 width: 250px;
 height: 200px;
 background-color: #ccc;
 border: 1px solid #000;
<div class="draggable">


    This is a dragging DIV element

<div class="draggable">

    This is a dragging DIV element


If you wish to use the above script and tweak its code, you can either copy it or download the sample file from here (which is also available at the beginning of this article). 

Bottom line

In this tutorial, I’ve provided you with a basic (yet functional) DIV dragging script, which can be easily included as part of your JavaScript applications. Of course, this is only a basic example, and it’s not intended to be used in production environments.

However, all isn’t lost. If you’re looking for a more robust and flexible method for building “drag-and-drop” DIVs, you’ll have to wait until the next article, where I’ll use a powerful, cross-browser library, in order to encapsulate most of the complexities involved in creating a DIV dragging JavaScript program. You won’t want to miss it!
