How append classes dynamically in jquery

Question

Hi All, in one of my variable i have something like var x='.myclass'. Now I want to append this var x while traversing the dom in jQuery.What should be the exact format for that.

Lets say I want to write

$("div.myclass a").someoperation();

now this .myclass has to dynamic, so I am trying something like

$("div"+x+"a").someoperation()

but this is not working, any clue.

Answer 1

var x = '.myclass';
$('div' + x + ' a').someoperation();

is equivalent to:

$('div.myclass a').someoperation();

so if the first doesn't work as the second it is because the value of x is not .myclass.

Answer 2

$("div"+x+" a").someoperation();

Just missing a space?

Answer 3

I think you missed a space here:

$("div"+x+" a").someoperation()

Answer 4

Here is another alternative

where x is ".myclass"

$('div').find(x).find('a')

Answer 5

x='.'+var_className
$("div"+x+" a").someoperation();
