jquery - 在页面Jquery上制作透明叠加

Question

嘿，我怎样才能做到基本上只有半透明的颜色覆盖整个页面，除了 1 个 div(这将是一条消息)

基本上，页面加载背景被半透明的黑色覆盖，但某个 div(在本例中为消息框)保持正常。

谢谢

你可以尝试 blockUI http://malsup.com/jquery/block/

The jQuery BlockUI Plugin lets you simulate synchronous behavior when using AJAX, without locking the browser^[1]. When activated, it will prevent user activity with the page (or part of the page) until it is deactivated. BlockUI adds elements to the DOM to give it both the appearance and behavior of blocking user interaction...

[1] Using the XMLHttpRequest object in synchronous mode causes the entire browser to lock until the remote call completes. This is usually not a desirable behavior.
