In this article, we are going to see how to toggle the visibility of a text canvas using FabricJS. The canvas means text written is movable, rotatable, resizable, and can be stretched. But in this article, we will toggle the visibility of the text. Further, the text itself cannot be edited like a textbox.
Approach: To make it possible, we are going to use a JavaScript library called FabricJS. After importing the library using CDN, we will create a canvas block in the body tag which will contain our text. After this, we will initialize instances of Canvas and Text provided by FabricJS and use the visible property to toggle visibility and render the Canvas on the Text as given in the example below.
Syntax:
fabric.text(text :string, visible: boolean);
Parameters: This function accepts two parameters as mentioned above and described below:
- text: It specifies the text.
- visible: It specifies the visibility of the text content. It contains a boolean value.
Program: This example uses FabricJS text visible property to make the visibility of text.
