jQuery 如何通过属性和值获取元素是变量？

Question

I defined a variable comment_id , it is the value of comment_id attribute of a form tag:

var comment_id = '44';

so can I insert the value of the variable into the following:

$( "div[comment_id = comment_id ]" )

so that I can locate the element that. with the attribute value.

I tried something like:

$( "div[comment_id = $comment_id ]" )

but not work.Any friend can help,I'm a Python guy and I'm very frustrated by JS it is very complicated and need code lots of code to do simple function.

Answer 1

try using the backtick character instead of the double quote

$(`div[comment_id = ${comment_id} ]`)
