Creating Svg Elements In Javascript

How to create svg elements with Javascript Code Zero

Are you ready to take your JavaScript skills to the next level? Creating SVG elements in JavaScript can seem like a daunting task at first, but it is actually quite simple. In this tutorial, we’ll walk you through the basics of creating SVG elements in JavaScript and provide some helpful tips to get you up and running.

SVG stands for Scalable Vector Graphics and is an XML-based vector image format for two-dimensional graphics. SVG images can be created and modified using JavaScript, which makes them ideal for creating interactive and dynamic web applications. In this tutorial, we’ll focus on creating SVG elements with JavaScript.

Getting Started with SVG in JavaScript

Before we dive into creating SVG elements, let’s take a look at the basics of SVG in JavaScript. The first step is to create an SVG element in your HTML. This is done using the tag, which will create a new SVG element and add it to your page. For example:

This will create a new SVG element with the specified width and height. You can add additional attributes to customize the SVG element, such as adding a background color or stroke width. However, this is not necessary for creating an SVG element in JavaScript.

Creating SVG Elements with JavaScript

Now that we have an SVG element on our page, we can start creating SVG elements with JavaScript. The first step is to get a reference to the SVG element on our page. We can do this using the getElementById() method, which will return a reference to the element with the specified ID. For example:

var svg = document.getElementById('svg');

Next, we can create a new SVG element using the createElementNS() method. This method takes two arguments: the namespace of the element and the name of the element. For example, we could create a new element by passing in the SVG namespace and the element name:

var circle = document.createElementNS("http://www.w3.org/2000/svg", "circle");

Once we have a reference to our SVG element and a new SVG element, we can add the new element to our SVG element using the appendChild() method. For example:

svg.appendChild(circle);

Once we have added the element to our SVG element, we can start setting attributes on the element. We can do this using the setAttribute() method. This method takes two arguments: the attribute name and the attribute value. For example, we could set the cx attribute to 50:

circle.setAttribute("cx", "50");

We can continue setting attributes until our element is configured how we want it. Once we are done, we can add the element to the page using the appendChild() method. For example:

document.body.appendChild(svg);

Conclusion

In this tutorial, we learned how to create SVG elements in JavaScript. We started by creating an SVG element in our HTML. Then, we used the getElementById() method to get a reference to the SVG element. Next, we used the createElementNS() method to create a new SVG element. We then used the appendChild() method to add the element to our SVG element. Finally, we used the setAttribute() method to set attributes on the element. We then added the SVG element to the page using the appendChild() method.

Creating SVG elements in JavaScript is a great way to create interactive and dynamic web applications. In this tutorial, we covered the basics of creating SVG elements in JavaScript. With a bit of practice, you’ll soon be creating awesome SVG elements in JavaScript!
