HTML ondrag Event Attribute
The HTML ondrag event attribute is triggered when the user drags an HTML element in an HTML document. The HTML image and link elements are dragged by default so there is no need to specify ondrag attribute on them.
Syntax
Following is the syntax −
<tagname ondrag=”script”></tagname>
Example
Let us see an example of HTML ondrag event Attribute −
<!DOCTYPE html>
<html>
<head>
<style>
body {
color: #000;
height: 100vh;
background-color: #FBAB7E;
background-image: linear-gradient(62deg, #FBAB7E 0%, #F7CE68 100%);
text-align: center;
}
.drop-target {
display: inline-block;
width: 150px;
height: 150px;
border: 2px solid #FFF;
margin: 1rem;
vertical-align: middle;
padding: 20px;
}
.circle {
background: #db133a;
height: 40px;
width: 40px;
border-radius: 50%;
}
.show {
color: #fff;
font-size: 1.2rem;
}
</style>
</head>
<body>
<h1>HTML ondrag Event Attribute Demo</h1>
<div class="drop-target" ondrop="drop(event)" ondragover="allowDrop(event)">
<p ondragstart="dragStart(event)" ondrag="dragging(event)" draggable="true" class="circle"></p>
</div>
<div class="drop-target" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
<p>Now try to drag and drop the red circle</p>
<div class="show"></div>
<script>
function dragStart(event) {
event.dataTransfer.setData("Text", event.target.id);
}
function dragging(event) {
document.querySelector(".show").innerHTML = "Circle is being dragged";
}
function allowDrop(event) {
event.preventDefault();
}
function drop(event) {
event.preventDefault();
event.target.appendChild(document.querySelector('.circle'));
document.querySelector(".show").innerHTML = "Circle was dropped";
}
</script>
</body>
</html>Output
Now try to drag and drop the red circle between the two boxes to observe how ondrag event attribute works.
