jQuery to loop through elements with the same class

try this...

$('.testimonial').each(function(){
    //if statement here 
    // use $(this) to reference the current div in the loop
    //you can try something like...


    if(condition){

    }


 });

Use each: 'i' is the postion in the array, obj is the DOM object that you are iterating (can be accessed through the jQuery wrapper $(this) as well).

$('.testimonial').each(function(i, obj) {
    //test
});

Check the api reference for more information.

It's pretty simple to do this without jQuery these days.

Without jQuery:

Just select the elements and use the .forEach() method to iterate over them:

const elements = document.querySelectorAll('.testimonial');
Array.from(elements).forEach((element, index) => {
  // conditional logic here.. access element
});

In older browsers:

var testimonials = document.querySelectorAll('.testimonial');
Array.prototype.forEach.call(testimonials, function(element, index) {
  // conditional logic here.. access element
});
