HTML table is stylized to have left column with content, main table and message line. Elements on the left side (green and orange) should be placed to the coloured table cells. After elements are correctly sited, appropriate message will be displayed.

This post describes how to maintain vertical scroll position after form submission or clicking on the link. Script will read vertical scroll position and append scroll value to the URL. After page is loaded, JavaScript function will search for the scroll parameter in the URL and set the scroll position.

If you need JavaScript dialog box, and you aren't satisfied with prompt, confirm, alert or window.open, then this page is right for you. Dialog box is emulated with two DIVs. First DIV will overlay whole page (transparency is styled to 60%) while second DIV will be positioned to the page center. That's nothing new but JavaScript code is short, well commented and closed in own namespace (for easier integration with other frameworks).

I was surprised when length of collected elements in DOM changed after new node was added. It seems that getElementsByTagName() doesn't return static collection of found elements but a kind of reference to the node list. No, this is not a bug, it's a feature and it has a name: "Live node list".
