How to use a variable in place of ID in jquery

Question

I have a div in which id is generated with index like gal1,gal2,gal3,gal4....

var clickid="gal" + index;
$('WANT TO PLACE clickid HERE').click();

I want to place the clickid variable inside the jquery selector. How to achieve it. This questions looks silly, but im a beginner eager to learn

Answer 1

Like this:

$('#' + clickid).click();

Since it is an id, you need to prepend # to it so that jQuery is able to find it out. This is similar to CSS :)

For more info, have a look at:

• jQuery ID Selector

Answer 2

$("#" + clickid).click();
