How to Loop Through Elements with the Same Class in jQuery Using \'each\' Function?

Looping Through Elements with the Same Class Using jQuery

Often, developers encounter the need to iterate through a collection of elements sharing a particular class attribute. This requirement arises when specific actions or tests need to be performed on each element individually.

In jQuery, the efficient and concise way to loop through elements with the same class is by using the "each" function. The "each" function takes two parameters: a callback function and the selector (in this case, ".testimonial").

Example:

<code class="javascript">$('.testimonial').each(function(i, obj) {
  // Test and perform action
});</code>

Within the callback function, the parameters "i" and "obj" are provided. "i" represents the current element's index in the matched set, while "obj" represents the DOM element itself. You can use jQuery's wrapper function "$(this)" to access the DOM object more easily.

This technique allows you to perform any necessary tests or actions on each element meeting the specified class criteria. For further details and usage examples,refer to the jQuery API reference.
