In this tutorial, we are going to learn how to lock the vertical scaling of a Textbox using FabricJS. Just as we can specify the position, colour, opacity and dimension of a textbox object in the canvas, we can also specify whether we want to stop scaling an object vertically. This can be done by using the lockScalingY property. Syntax new fabric.Textbox(text: String, { lockScalingY : Boolean }: Object) Parameters text − This parameter accepts a String which is the text string that we want to display inside our textbox. options (optional) − This parameter is an Object ...

In this tutorial, we are going to learn how to lock the vertical movement of a Textbox using FabricJS. Just as we can specify the position, colour, opacity and dimension of a textbox object in the canvas, we can also specify whether we want it to move only in the X-axis. This can be done by using the lockMovementY property. Syntax new fabric.Textbox(text: String, { lockMovementY: Boolean }: Object) Parameters text − This parameter accepts a String which is the text string that we want to display inside our textbox. options (optional) − This parameter is an Object ...

In this tutorial, we are going to learn how to lock the rotation of a Textbox using FabricJS. Just as we can specify the position, colour, opacity and dimension of a textbox object in the canvas, we can also specify whether we want to allow rotation or not. This can be done by using the lockRotation property. Syntax new fabric.Textbox(text: String, { lockRotation : Boolean }: Object) Parameters text − This parameter accepts a String which is the text string that we want to display inside our textbox. options (optional) − This parameter is an Object which provides ...

In this tutorial, we are going to learn how to lock the horizontal skewing of a Textbox using FabricJS. Just as we can specify the position, colour, opacity and dimension of a textbox object in the canvas, we can also specify whether we want to stop skewing an object horizontally. This can be done by using the lockSkewingX property. Syntax new fabric.Textbox(text: String, { lockSkewingX : Boolean }: Object) Parameters text − This parameter accepts a String which is the text string that we want to display inside our textbox. options (optional) − This parameter is an Object ...

In this tutorial, we are going to learn to change strings to be displayed as a superscript using JavaScript. As the name suggests, the superscript string is displayed at the half-height of the normal string. Also, characters of the superscript string are smaller than the normal string characters.There are a lot of uses of the superscript string while writing the mathematical formulas. For example, A2, B2, 105, etc. Also, we can use the superscript to show the chemical formulas such as O22-, H-, etc.Here, using HTML or JavaScript, users can learn to display string as a superscript.Display string as subscript ...

In this tutorial, we will learn to change the string displayed as a subscript using JavaScript. The meaning of the subscript string is a string that displays right after the string with a small letter and hangs below. For example, In the Astart, ‘start’ is the subscript string shown in the small letter right after A and hangs below. The substring uses in many fields such as Mathematics, chemicals, etc. It is useful to represent the chemical name. For example, H2, N2, O2, etc. Also, we can use it in mathematics to show the symbols such as X2, A2, etc. ... Read More
In this tutorial, we will learn to change the button label in the confirm box using JavaScript. The confirm box is useful for taking the confirmation from the user. For example, when you try to delete something from your account on some websites, they show you a popup box containing a message like “Are you sure to delete ….?”.

Programmers often need to open a new popup window to show another webpage without redirecting the user to the other webpage. In this situation, developers use the window.open() method to open the new browser window. Also, we can style the popup window and set the height and width. Also, we can change the position of the popup window to look it better. Sample Popup Window In this section, we will create a sample popup window to get familiar with the how window.open() method works. ... Read More
