How to Use jQuery to Iterate Through Elements with the Same Class
When working with multiple elements of the same class, it becomes necessary to access and manipulate them individually. jQuery provides an efficient way to loop through these elements using the .each() method.
Question:
I have a collection of divs with the class "testimonial" and I need a way to iterate through them using jQuery to check if a particular condition is met. If the condition is true, I want to perform a specific action.
Answer:
To achieve this, you can use the .each() method as follows:
$('.testimonial').each(function(i, obj) {
// Your code here...
});
Within the .each() callback function, you have access to the index of the current element within the array (i) and the DOM object of the element (obj). You can use the jQuery wrapper $(this) to access the DOM object directly.
For example, if you want to check if the current div has a specific class and perform an action if it does, you could use the following code:
$('.testimonial').each(function() {
if ($(this).hasClass('active')) {
// Perform your action here...
}
});
The jQuery documentation provides detailed information and examples for the .each() method, which you can reference for more advanced usage scenarios.

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.
