E.g. I want to find a the div which has the attribute data-divNumber=\
div
data-divNumber=\
You need to do some string addition to get the number into your selector and the value needs to be quoted.
var number = 6; var myDiv = $('[data-divNumber="' + number + '"]');
What you're trying to produce after the string addition is this result:
$('[data-divNumber="6"]');
