Question

I have a little problem with this jquery code:
If I call the openMenu function, directly, it works, but inside the if it does not.

 $(document).ready(function() {

 function checkMenu() {

 if($(this).find('ul').css('display') == 'none') {
    openMenu();
 } else { 
    closeMenu();
 }
 }

 function openMenu() {  
    $(this).find('ul').css({display: "block"});
 }

function closeMenu() {
  $(this).find('ul').css({display: "none"});
 }


 $('ul li:has(ul)').click(checkMenu);
 });

Answer 1

You could make it easy on yourself and use toggle()

$('ul li:has(ul)').click(function(){
    $(this).find('ul').toggle();
});
