jQuery $(window).resize is not working consistently.


I am trying to use jQuery to make mobile drop down menu, but it only works sometimes. Does anyone know what I am doing wrong?

Here is the temporary url: www.nmvwebdesign.us

Here is the java code:

//Create mobile drop down menu
function toggleMenu(){
    if ($('#sidebar').width() < 200 ){
        //initially hide navigation
        $("#sidebar ul").hide();

        //toggle navigation when menu is clicked
        $("#menu").click(function() {
            $("#sidebar ul").toggle();
    }else $("#sidebar ul").show();

//call function on load and page resize

I would appreciate any help!

Thanks! Nicole

OK - I think I've worked out the issue.

It revolves around your if statement. If we read it carefully, it says IF the sidebar's width is less than 200 px, than 1) hide it and 2) bind the click event to it.

It looks to me like this only happens when the page LOADS with the menu width less than 200px, and if the page loads with a menu wider than this the click event doesn't get bound.

Thank you for looking in to this so thoroughly! Here is a little more about what is going on. I only have one media query (768px) in which the menu is set to a width of 200px. Any screen smaller than that, the menu comes out to a width of 169px.

Toggling seems to work when: The page is loaded as a large screen and then restored down or dragged to a small screen.

Toggling seems to not work when: The page is loaded as a small screen and then re-sized.

Do you know what could be causing this?

I am still having the issue. Sometimes the menu doesn't toggle when you click on it.

Might an alternative solution be to use responsive CSS to have your menu minimised, always bind the click event to the menu button and then simply set it to display none on screens larger than a certain width?

Thank you for your help Cian! I just replaced

  if ($('#sidebar').width() < 200 ){


 if ($(window).width() < 768 ){

Now it seems to work! :)

Great! Thanks for following up with what your fix is. Hopefully it will help others who face similar issues!
