Moving and Editing Text on a Canvas with Fabric.js
Guide to Designing an Interactive Text Box on a Fabric.js Canvas
Hey there, folks! Today, we're going to learn how to create a movable and editable textbox on a canvas using the Fabric.js library.
Let's Get Started!
First, we'll need the Fabric.js library. We'll import it via a CDN.
```html
```
Now, let's create a canvas block within the tag. After that, we'll initialize instances of and provided by Fabric.js and render the Canvas on the Textbox.
```html
```
Designing Our Textbox
In this section, we'll design the pre-created structure and add JavaScript functionality to move the text around the canvas.
```javascriptlet textbox = new fabric.Text('Hello World', { left: 50, top: 50, selectable: true, editable: true, originX: 'center', originY: 'center', lockMovementX: false, lockMovementY: false, maxWidth: 200, maxHeight: 200,});
canvas.add(textbox);```
Making Our Textbox Interactive
Now, let's handle textbox movement inside the with these simple functions:
And that's it! You've created a movable and editable textbox on a canvas with Fabric.js.

_Enrichment Data:
To disable the selectability of a canvas object, such as a circle, using Fabric.js, you can set the property of the object to .
Using Fabric.js in JavaScript
```javascript// Import Fabric.jsimport { fabric } from 'fabric';
// Create a new canvaslet canvas = new fabric.Canvas('canvasElement');
// Create a circle objectlet circle = new fabric.Circle({ radius: 50, fill: 'blue', left: 100, top: 100, // Disable selectability selectable: false});
// Add the circle to the canvascanvas.add(circle);```
Using HTML
First, ensure you have an HTML element for your canvas:
```html
```
Then, use the JavaScript code above to create and configure the Fabric.js canvas and its objects.
Explanation
- Property: Setting to prevents the object from being selected (e.g., by clicking on it) but does not prevent events from firing on it[1][4].
- Canvas Element: Ensure your canvas element is correctly referenced in the DOM using its ID ( in the example).
- Fabric.js Version: Ensure you are using a compatible version of Fabric.js, as functionality might change between versions.
Additional Notes
If you are working with groups or multiple objects, you might need to apply this setting to each object individually. Additionally, if you have grouped objects, you might need to set , , and other lock properties to prevent movement within the group without affecting selectability[3].
