select child element using parent class

Question

In jquery we put select child element using like this

$('.parentClass .childClass')....

is there any way to select child class using parent class in javascript

Answer 1

For Javascript try this

document.querySelectorAll('.parentClass .childClass')

You can use css selector as argument in this function. This function not supported in lower version of IE

Answer 2

html:

<ul class="example">
  <li class="child">Coffee</li>
  <li class="child">Tea</li>
</ul>

javascript:

var list = document.getElementsByClassName("example")[0];
list.getElementsByClassName("child")[0].innerHTML = "Milk";

Answer 3

The question is not clear but if you want to get all nested child elements which has class, this can be work:

$("parentElementSelector").find("[class]")

But if you want to just next child elements you can use this:

$("parentElementSelector").children("[class]")
