Javascript DOM ondrag Event via HTML Tag ondrag function

Introduction

In JavaScript: 

object.ondrag = function(){
       myScript};

This example uses the HTML DOM to assign "ondragstart", "ondrag", "ondragover" and "ondrop" events to the document object.

Drag the p element back and forth between the two rectangles:

View in separate window 

<!DOCTYPE HTML>
<html>
<head>
<style>
.droptarget {//from  w  w  w. j  a v a  2s  .  c o  m
  float: left;
  width: 100px;
  height: 35px;
  margin: 15px;
  padding: 10px;
  border: 1px solid #aaaaaa;
}
</style>
</head>
<body>
<div class="droptarget">
  <p id="dragtarget" draggable="true">Drag me!</p>
</div>

<div class="droptarget"></div>
<p id="demo"></p>
<script>
/* Events fired on the drag target */
document.ondragstart = function(event) {
  event.dataTransfer.setData("Text", event.target.id);
};

document.ondrag = function(event) {
  document.getElementById("demo").innerHTML = "The p element is being dragged";
};

/* Events fired on the drop target */
document.ondragover = function(event) {
  event.preventDefault();
};

document.ondrop = function(event) {
  event.preventDefault();
  if ( event.target.className == "droptarget" ) {
    var data = event.dataTransfer.getData("Text");
    event.target.appendChild(document.getElementById(data));
    document.getElementById("demo").innerHTML = "The p element was dropped";
  }
};
