divs  = $('.testimonial')
for(ind in divs){
  div = divs[ind];
  //do whatever you want
}

试试这个…

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


    if(condition){

    }


 });

我可能忽略了部分问题，但我相信你可以简单地这样做:

$('.testimonial').each((index, element) => {
    if (/* Condition */) {
        // Do Something
    }
});

这使用jQuery的每个方法:https://learn.jquery.com/using-jquery-core/iterating/

divs  = $('.testimonial')
for(ind in divs){
  div = divs[ind];
  //do whatever you want
}

使用简单的for循环:

var testimonials= $('.testimonial');
for (var i = 0; i < testimonials.length; i++) {
  // Using $() to re-wrap the element.
  $(testimonials[i]).text('a');
}

试试这个例子

Html

<div class="testimonial" data-index="1">
    Testimonial 1
</div>
<div class="testimonial" data-index="2">
    Testimonial 2
</div>
<div class="testimonial" data-index="3">
    Testimonial 3
</div>
<div class="testimonial" data-index="4">
    Testimonial 4
</div>
<div class="testimonial" data-index="5">
    Testimonial 5
</div>

当我们想要访问那些数据索引大于2的div时，我们需要这个jquery。

$('div[class="testimonial"]').each(function(index,item){
    if(parseInt($(item).data('index'))>2){
        $(item).html('Testimonial '+(index+1)+' by each loop');
    }
});
