You need to use and &&

instead of to check if the element exists. The jQuery selector returns an object, even the selector returns an item None . Thus, using .length will return zero if no element is returned by the selector and is greater than zero when an element is returned by the selector.AND

length 



if($("#one").length && $("#two").length) {
