Force repaint after resizing window

repaint.js

(function(window) {
    var resizeTimeoutId;

    // instead replacing event attach
    // if you want to consider other browsers use if (window.addEventListener)
    // window.onresize = window_resize;
    if (window.attachEvent) {
        window.attachEvent('onresize', function() {
            window_resize(e);
        });
    }

    function repaint () {
        // console.log('resizeTimeoutId',resizeTimeoutId);
        // force repaint i.e. IE7 bug
        document.body.className = document.body.className;
    }

    function window_resize(e) {
        // console.log('window_resize');
        window.clearTimeout(resizeTimeoutId);
        resizeTimeoutId = window.setTimeout(repaint, 100);
    }
})(window);
