jQuery CSS to pure Javascript

Question

I am trying to use jQuery as little as possible and I would like to translate some jQuery code to pure JS.

I have this:

$(".myDiv").css({"width": 500});

What is the pure JS equivalent of the code above?

Answer 1

var els = document.querySelectorAll('.myDiv');

// If you want to get elements using its class name
// var els = document.getElementsByClassName('myDiv');

for(var i = 0, length = els.length; i < length; i++) {
   els[i].style.width = '500px';
}

By using forEach:

var els = document.querySelectorAll('.myDiv');

els.forEach(function(el, ind) {
  el.style.width = '500px';
});
