Force rendering a DOM element when Webkit is acting up

gistfile1.coffee

forceRerenderOnWebkit: ->
  @el.parentNode.style.cssText += ';-webkit-transform:rotateZ(0deg)'
  @el.parentNode.offsetHeight
  @el.parentNode.style.cssText += ';-webkit-transform:none'   

Have you tried modifying the class name and/or id? It worked for me on several occasions, eg. forcing iOS 5 to render position:fixed iframes whine scrolling. Any change triggered a rerender, so appending a bogus class or assigning to the id worked.

Should be enough to get the computed style of the element to force a repaint.

I don't have a better solution, but your suggestion just fixed a bug I had in Opera. Thanks :-)

I also found this plugin:
http://plugins.jquery.com/files/jquery.forceredraw-1.0.3.js_.txt

It confirms @KrofDrakula's suggestion for most cases but also has a "brutal" fallback where it changes CSS as you do in your suggestion, just using a 1ms timeout before it changes it back

@gr2m: It would seem the "brutal" version here changing the padding seems a bit overkill; I use the following code for a rock solid repaint:

function forceRedraw(el) {
  var t = el.ownerDocument.createTextNode(' ');
  el.appendChild(t);
  setTimeout(function() { el.removeChild(t); }, 0);
}

@gr2m damn, i just suggested a class named "repaint", not "redraw" ;)

but i still favor a solution which doesn't need to touch the dom at all

Hi guys! Thanks to all for the suggestions... So, anyone know what is the most optimal way to force a reflow? Any jsPerf there? :)

I'll add this one to the pile https://gist.github.com/digitalicarus/c83d9b4c80ab35f7452a
