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 tried morewry answer but it does not work for me. I had trouble to have the same clientWidth with safari comparing to others browsers and this code solved the problem:

var get_safe_value = function(elm,callback){
    var sty = elm.style
    sty.transform = "translateZ(1px)";
    var ret = callback(elm)//you can get here the value you want
    sty.transform = "";
    return ret
}
// for safari to have the good clientWidth
var $fBody = document.body //the element you need to fix
var clientW = get_safe_value($fBody,function(elm){return $fBody.clientWidth})

It is really strange because if I try again to get the clientWidth after get_safe_value, I obtain a bad value with safari, the getter has to be between sty.transform = "translateZ(1px)"; and sty.transform = "";

The other solution that works definitively is

var $fBody = document.body //the element you need to fix
$fBody.style.display = 'none';
var temp = $.body.offsetHeight;
$fBody.style.display = ""
temp = $.body.offsetHeight;

var clientW = $fBody.clientWidth

The problem is that you lose focus and scroll states.
