Button class= xxx12

Can i click button automaticly with jquery?

i tried these;

Code:

$("#xxx12").click();

Code:

$("#xxx12").trigger('click');

Code:

$(".xxx12").click();

Code:

$(".xxx12").trigger('click');

Code:

$(document).ready(function() {
$("#xxx12").click();
});

 

Is there supposed to be a space at the beginning of that class?

Code:

$('[class=" xxx12"]').click();
