How to Iterate Through Elements with the Same Class Using jQuery and Perform Conditional Actions?

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...
});
Copy after login

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...
    }
});
Copy after login

The jQuery documentation provides detailed information and examples for the .each() method, which you can reference for more advanced usage scenarios.
