Creating JavaScript Objects with Variable Class Names
You're attempting to create a JavaScript object using a variable string to define the class name. Here's an adjusted version of your code that should work:
// Define the class
var MyClass = class { };
// Store the class name in a variable
var classNameString = 'MyClass';
// Instantiate the object
var myObject = new window[classNameString];
The adjustment is made in the object instantiation line, where we use the window[classNameString] notation to access the class object dynamically. This works because JavaScript classes are assigned to the global window object when defined.
However, note that this approach requires the class to be defined before creating the object. If you want to create an object before defining its class, you'll need to use a different approach, such as dynamically evaluating the code that defines the class based on the variable string.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
