How to exit editing state in IText using FabricJS?

FabricJS Javascript HTML5 Canvas

In this tutorial, we are going to learn about how to exit editing state in IText using FabricJS. The IText class was introduced in FabricJS version 1.4, extends fabric.Text and is used to create IText instances. An IText instance gives us the freedom to select, cut, paste or add new text without additional configurations. There are also various supported key combinations and mouse/touch combinations which make text interactive which are not provided in Text.

Textbox, however, which is based on IText allows us to resize the text rectangle and wraps lines automatically. This is not true for IText as height is not adjusted based on the wrapping of lines. We can manipulate our IText object by using various properties. Likewise, we can exit the editing state by using the exitEditing method.

Syntax

exitEditing(): Itext.IText

Example 1

Using the isEditing property only

Let’s see a code example to see how the IText object looks like when the isEditing property is used by itself and a true value is passed to turn on the editing mode. Since we have not used the exitEditing() method, our IText object will be in editing mode.

   <canvas id="canvas"></canvas>
   
   <script>
      // Initiate a canvas instance
      var canvas = new fabric.Canvas("canvas");
      canvas.setWidth(document.body.scrollWidth);
      canvas.setHeight(250);

      // Initiate an itext object
      var itext = new fabric.IText("Add sample text here.", {
         width: 300,
         left: 60,
         top: 70,
         fill: "red",
         isEditing: true,
      });

      // Add it to the canvas
      canvas.add(itext);
   </script>
</body>
</html>

Example 2

Using the exitEditing method along with the isEditing property

Let’s see a code example to see how the IText object looks like when the exitEditing method is used in conjunction with the isEditing property. Since we are passing the isEditing property a true value, the IText object should be in editing mode. However, as soon as we use the exitEditing method, the editing mode is exited.

      // Initiate a canvas instance
      var canvas = new fabric.Canvas("canvas");
      canvas.setWidth(document.body.scrollWidth);
      canvas.setHeight(250);

      // Initiate an itext object
      var itext = new fabric.IText("Add sample text here.", {
         width: 300,
         left: 60,
         top: 70,
         fill: "red",
         isEditing: true,
      });

      // Add it to the canvas
      canvas.add(itext);

      // Using the exitEditing method
      itext.exitEditing();
   </script>
</body>
