Modernizr.addTest('cssscrollbar', function() {
// Tested Element
var test = document.createElement('div'),
// Fake body
fake = false,
root = document.body || (function () {
fake = true;
return document.documentElement.appendChild(document.createElement('body'));
}()),
property = 'scrollbar{width:0px;}';
// Force scrollbar
test.id = '__sb';
test.style.overflow = 'scroll';
test.style.width = '40px';
// Apply scrollbar style for all vendors
test.innerHTML = '­<style>#'+Modernizr._prefixes.join(property+' #__sb::').split('#').slice(1).join('#')+property+'</style>';
root.appendChild(test);
// If css scrollbar is supported, than the scrollWidth should not be impacted
var ret = test.scrollWidth == 40;
// Cleaning
document.body.removeChild(test);
if (fake) {
document.documentElement.removeChild(root);
}
return ret;
});
如果你添加这个,那么你将拥有对现代化器的 cssscrollbar 支持........
