jQuery to loop through elements with the same class

I have a load of divs with the class testimonial and I want to use jquery to loop through them to check for each div if a specific condition is true. If it is true, it should perform an action.

Does anyone know how I would do this?

Answer

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.

Answer

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){

    }


 });
Answer

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:

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

Try this example

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>

When we want to access those divs which has data-index greater than 2 then we need this jquery.

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

Answer

you can do it this way

$('.testimonial').each(function(index, obj){
    //you can use this to access the current item
});
Answer
divs  = $('.testimonial')
for(ind in divs){
  div = divs[ind];
  //do whatever you want
}
Answer

You can do this concisely using .filter. The following example will hide all .testimonial divs containing the word "something":

$(".testimonial").filter(function() {
    return $(this).text().toLowerCase().indexOf("something") !== -1;
}).hide();
Answer

With a simple for loop:

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

I may be missing part of the question, but I believe you can simply do this:

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

This uses jQuery's each method: https://learn.jquery.com/using-jquery-core/iterating/

Without jQuery updated

document.querySelectorAll('.testimonial').forEach(function (element, index) {
    element.innerHTML = 'Testimonial ' + (index + 1);
});
<div class="testimonial"></div>
<div class="testimonial"></div>

Answer
$('.testimonal').each(function(i,v){
  if (condition) {
    doSomething();
  }
});
Answer

More precise:

$.each($('.testimonal'), function(index, value) { 
    console.log(index + ':' + value); 
});
Answer

In JavaScript ES6 .forEach() over an array-like NodeList collection given by Element.querySelectorAll()

document.querySelectorAll('.testimonial').forEach( el => {
  el.style.color = 'red';
  console.log( `Element ${el.tagName} with ID #${el.id} says: ${el.textContent}` );
});
<p class="testimonial" id="1">This is some text</p>
<div class="testimonial" id="2">Lorem ipsum</div>

Answer

You could use the jQuery $each method to loop through all the elements with class testimonial. i => is the index of the element in collection and val gives you the object of that particular element and you can use "val" to further access the properties of your element and check your condition.

$.each($('.testimonal'), function(i, val) { 
    if(your condition){
       //your action
    }
});
Answer

jQuery's .eq() can help you traverse through elements with an indexed approach.

var testimonialElements = $(".testimonial");
for(var i=0; i<testimonialElements.length; i++){
    var element = testimonialElements.eq(i);
    //do something with element
}
