<!DOCTYPE html>
<html>
<head>
<!-- Adding the Fabric JS Library-->
<script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/510/fabric.min.js"></script>
</head>
<body>
<h2 id="Default-style-of-controlling-corners">Default style of controlling corners</h2>
<p>Click on the rectangle to see the default style of its controlling corners.</p>
<canvas id="canvas"></canvas>
<script>
// Initiate a canvas instance
var canvas = new fabric.Canvas("canvas");
canvas.setWidth(document.body.scrollWidth);
canvas.setHeight(250);
// Initiate a rectangle object
var rect = new fabric.Rect({
left: 125,
top: 90,
width: 170,
height: 70,
fill: "#cf1020",
borderColor: "black",
borderScaleFactor: 3,
cornerColor: "#3b7a57",
});
// Add it to the canvas
canvas.add(rect);
</script>
</body>
</html>Copy after loginExample
Passing cornerStyle as key with value "circle"
We can specify the actively selected control horn
Object by passing the value as a "circle" or "rectangle". Passing the value as a "circle" will make

Demystifying JavaScript: What It Does and Why It Matters
Apr 09, 2025 am 12:07 AM
JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
