How can I force WebKit to redraw/repaint to propagate style changes?

Question

I have some trivial JavaScript to effect a style change:

sel = document.getElementById(\'my_id\');
sel.className = sel.className.replace(/item-[1-9]-selected         


        

Answer 1

I came up here because I needed to redraw scrollbars in Chrome after changing its css.

If someone's having the same problem, I solved it by calling this function:

//Hack to force scroll redraw
function scrollReDraw() {
    $('body').css('overflow', 'hidden').height();
    $('body').css('overflow', 'auto');
}

This method is not the best solution, but it may work with everything, hiding and showing the element that needs to be redraw may solve every problem.

Here is the fiddle where I used it: http://jsfiddle.net/promatik/wZwJz/18/
