i want use jquery select button , click on it? tried using : jquery(".btn btn-primary").click() not working

you trying select element both classes, therefore selector should .btn.btn-primary.

$('.btn.btn-primary').click(); 

you trying select element class .btn-primary descendant of .btn element.
