Problem with a code, Hope you can help me with that

You didn’t check if this element exists:

$('.widget:last-child', $(sidebarElement));

Mmmm,

Where do I paste it?

Can you paste all the code together for me?

Thank you

Oh, if you don’t know what that means then you need to link us the Webpage with the problem.

Ok

I would like it to appear in the last widget of the #widgets sidebar.

You can see the sidebar here

Thank you very much

You have no elements on that page with the ID of “sidebar”, I don’t understand how that’s going to work in the first place

I followed the tutorial here.

The div of my sidebar is #widgets

I need to change:
var sidebarElement = $(‘div#secondary’);
to this:
var sidebarElement = $(‘div#widgets’);

Well, I did so, but the only problem is line 17

Do you know what I mean?

Then again, you have no elements with the class of “widget” inside your sidebar

var lastWidget = $('.widget:last-child', $(sidebarElement));

Ohh OK

are you able to generate me the right code?

I just want to make my last widget in the sidebar to fade in.

Thank you for the help man

jQuery(document).ready(function($) {

    // Fade in the last sidebar widget

    var sidebarElement = $('#widgets'),
        widgetDisplayed = false,
        lastWidget,
        lastWidgetOffset; 

    // Check if the sidebar exists
    if (sidebarElement.length > 0) {

        // Get the last widget in the sidebar, and its position on screen

        lastWidget = $('> div:last-child', sidebarElement);
        lastWidgetOffset = lastWidget.offset().top - 100;

        // Hide the last widget
        lastWidget.hide();

        // Check if user scroll have reached the top of the last widget and display it
        $(document).scroll(function() {

            // If the widget has been displayed, we don't need to keep doing a check.

            if (!widgetDisplayed) {
                if ($(this).scrollTop() > lastWidgetOffset) {
                    lastWidget.fadeIn('slow').addClass('wpbstickywidget');
                    widgetDisplayed = true;
                }
            }
        });
    }
});

It’s more appealing for someone to help when they’re not doing all the work for you.

Works like a charm
Thank you very much!
