Question

我的网站出了问题。我添加了一个预加载器，假设在页面之前加载，但实际上它在整个页面之后开始几毫秒，所以它给出了一个非常不愉快的效果（页面显示一毫秒而预加载器失去了他的主要目的）。

到目前为止，我的代码如下（它是一个wordpress网站）：HTML

<body>
<header>Stuff in the header</header>
    <div class="loader-wrapper">
        <div class="loader"></div>
        <div class="loader-section section-left"></div>
        <div class="loader-section section-right"></div>
    </div>
</body>

JQUERY：

$(document).ready(function() {
    setTimeout(function(){
        $('body').addClass('loaded');
    }, 3000);
    var carousel = $("#carousel").flipster({
        style: 'carousel',
        spacing: -0.3,
        nav: false,
        buttons: true,
        scrollwheel: false,
    });
    $(".rotator").rotator();
});

更新：

CSS：

.loader-wrapper, .rotator {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;

任何提示？

Answer 1

为了使其正常工作，您需要添加如下所示的样式，

body {
    visibility: hidden;
}
.loader-wrapper {
    z-index: 99;
    display: block;
}

然后在窗口加载时，

$(window).load(function() {
    $('.loader-wrapper').hide();
    $('html, body').css('visibility', 'visible');
});

预加载器在页面后面开始
