jQuery selectors with variables

How to mix variables with selectors?

I have ID variable.

I want to select image with this id from div #one.

jQuery('#one img .id') is the selector. I've tried $('#one img .'+id) but doesn't work.

Edit: Based on your comment below, you would use this:

$('#one img.'+id)

In your question you have a space between img and the .class, I've simply removed that so you get img.className or img.'+className

With the introduction of template literals in ECMAScript 2015, you can also do

$(`#one img.${id}`)
