有一个弹出式锁定屏幕，直到时间的页面被完全加载弹出式、有一个、加载、屏幕
我的页面需要相当长的一段时间来加载各种控制和菜单的图像。我想说明一个弹出窗口，上面有进度条。用户必须不能够访问在网页浏览器的原始页面时该弹出显示。
My page takes quite sometime to load a variety of controls and menu images. I want to show a popup window with progress bar on it. The user must not be able to access the original page on the web-browser when this popup is showing.
在页面完全加载，这个弹出必须消失。如何做到这一点？
When the page has loaded completely, this popup must disappear. How to do this?
推荐答案
要做到这一点是与覆盖最简单的方法 - 一个绝对定位的＆LT; DIV＆GT; 覆盖整个页面，并具有较高的的z-index 。一旦你的页面加载完（即加载事件触发），那么你可以删除＆LT; DIV＆GT;
The easiest way to do this would be with an overlay -- an absolutely-positioned <div> that covers the entire page and has a high z-index. Once your page has finished loading (i.e. the loaded event fires) then you can remove the <div>.
一个粗略的例子造型用途：
A rough example for styling purposes:
<html>
<head>
<style type="text/css">
#loading-overlay { position: absolute; top: 0; left: 0; right: 0; bottom: 0; background-color: #000; opacity: 0.7; }
#loading-message { position: absolute; width: 400px; height: 100px; line-height: 100px; background-color: #fff; text-align: center; font-size: 1.2em; left: 50%; top: 50%; margin-left: -200px; margin-top: -50px; }
</style>
</head>
<body>
<div id="loading-overlay"></div>
<div id="loading-message">Loading page, please wait...</div>
<!-- rest of page -->
<p>The rest of the page goes here...</p>
</body>
</html>
注意控制可能有自己的装事件（如＆LT; IMG＆GT; 标签做），这可能会发生火灾后的页面已经完全结束。你将不得不尝试是肯定的。
Be aware that controls may have their own "loaded" event (e.g. <img> tags do), which may fire after the page has completely finished. You would have to experiment to be certain.
