Implement Basic Animation in JavaScript
To implement basic Animation in JavaScript, use the DOM object properties and JavaScript. The following list contains different DOM methods.
- We are using the JavaScript function getElementById() to get a DOM object and then assigning it to a global variable imgObj.
- We have defined an initialization function init() to an initialize imgObj where we have to set its position and left attributes.
- We are calling an initialization function at the time of window load.
- Finally, we are calling moveRight() function to increase the left distance by 10 pixels. You could additionally set it to a negative value to move it to the left side.
<html>
<head>
<title>JavaScript Animation</title>
<script>
<!--
var imgObj = null;
function init() {
imgObj = document.getElementById('myImage');
imgObj.style.position= 'relative';
imgObj.style.left = '0px';
}
function moveRight() {
imgObj.style.left = parseInt(imgObj.style.left) + 10 + 'px';
}
window.onload =init;
//-->
</script>
</head>
<body>
<form>
<img id="myImage" src="/https/www.tutorialspoint.com/images/html.gif" />
<p>Click button below to move the image to right</p>
<input type="button" value="Click Me" onclick="moveRight();" />
</form>
</body>
</html>
