我正在尝试防止FF＆IE中的FOUC。加载我的css异步，（可以理解）会导致它。设置隐藏功能，然后显示正文可以在Chrome上使用，但不能在IE / FF上使用。
我已经尝试了在线显示的所有解决方案，这些解决方案应该都能正常工作，而且没有。想知道我的代码中是否有一些东西被忽略了；或其他人知道的解决方案？

最佳答案
所有CSS完成加载后，我将删除display：none样式，如下所示
window.onload = function(){
var resources = [
{ url: "//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css", type: "css"},
{ url: "/css/main-min.css", type: "css"},
{ url: "//ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js", type: "js"},
{ url: "//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js", type: "js"},
{ url: "/js/main-min.js", type: "js"}
];
var head = document.getElementsByTagName("head")[0];
var cssToLoad = 0;
var loadOrError = function (e) {
cssToLoad -= 1;
if (cssToLoad < 0) { // prevent early trigger
document.body.style.removeProperty('display');
}
};
resource.forEach(function(resource) {
var element;
if (resource.type == "js") {
element = document.createElement('script');
element.setAttribute("type", "text/javascript");
element.setAttribute("src", resource.url);
} else if (resource.type == "css") {
cssToLoad += 1;
element = document.createElement("link");
element.setAttribute("rel", "stylesheet");
element.setAttribute("type", "text/css");
element.setAttribute("href", resource.url);
element.addEventListener('load', loadOrError);
element.addEventListener('error', loadOrError);
}
if (typeof element != "undefined") {
head.appendChild(element);
}
});
loadOrError(); // end prevent early trigger
};
