$('.child_1').closest('.parent').find('.child_2');

closest() will get you the first parent that matches the given query string.

OP is asking how to do this in javascript – Carsten Løvbo Andersen Sep 14 '17 at 11:23
It is javascript of course, and he also included the `jquery` tag, so I think this is appropriate. – Catalin Iancu Sep 14 '17 at 11:26

"How do I call the above JQuery syntax using Javascript syntax?" The question is clear – SilverSurfer Sep 14 '17 at 11:26
By JS, he means vanilla JS – Deepansh Sachdeva Sep 14 '17 at 11:27
In my case, i can only provide ID to child_1, and it has to call to child_2 using a parent, both not having any ID – Atul Kumar Sep 14 '17 at 11:35
Then a class approach when the `id` is unknown is correct, like `$('#child_1').closest('.parent').find('.child_2');`, with `#` denoting the id and `.` denoting a class. – Catalin Iancu Sep 14 '17 at 11:38

You can do like this:

$('.child_1').parents('.parent:first').find('.class:eq(1)');

First notice that I have used :first to determine the proper parent of the child_1. Then, I have put in eq(1) because child counting starts from 0;

Refer to this answer to Get parents of element in JS and then iterate over the parents to get their child using querySelector

var parents = getParents( document.getElementByClassName('.child_1')[0]);
var children = [];

parents.forEach(function (parent) {
    children.push(parent.querySelector('.child_2'));
});

This example was not entirely clear to me. In my case, i can only provide ID to child_1, and it has to call to child_2 using a parent, both not having any ID – Atul Kumar Sep 14 '17 at 11:34
@AtulKumar didn't get what you require – Deepansh Sachdeva Sep 14 '17 at 11:37
The answer is almost complete, but I think you also need a way to specify which parent, by using a class maybe `.parent`, if the id is not available. – Catalin Iancu Sep 14 '17 at 11:45
@CatalinIancu Yes, but according to jQuery provided in question, it is asking for parents, not parent – Deepansh Sachdeva Sep 14 '17 at 11:47
@DeepanshSachdeva close to what you suggested. Yes, I do have to specify which parent I need to go. I guess it is close, but gives an error, parents is not a function. – Atul Kumar Sep 14 '17 at 11:49
I think the function `getParents()` is not a JS standard function, so you need to define what it does. – Catalin Iancu Sep 14 '17 at 11:52
@Catalinlancu that function is from the answer I mentioned in mine answer. – Deepansh Sachdeva Sep 14 '17 at 11:56
@AtulKumar edit the question with the details about what you want to do along with an example. It would help in resolving your issue more quickly. – Deepansh Sachdeva Sep 14 '17 at 13:24
