我有一个网站here。
当您打开网站时,2秒后,您会在后台看到一些文字。这是JavaScript弹出窗口的一部分。我试图让它保持在其他一切的顶部。当有人到达网站时,它会自动出现。它只显示我对网站所做的更新。
正如你所看到的,它显然不是最重要的。这是一个表格弹出窗口。没有我可以应用的z-index。我试过的一件事没有效果就是。
<body onblur="self.focus();">
我的jQuery会妨碍吗?

function popup(windowname) {
blanket_size(windowname);
window_pos(windowname);
toggle('blanket');
toggle(windowname);
}
一旦所有这些代码都正确插入,每次用户重新刷新页面时,您都会在页面上获得居中的弹出窗口(onload)。 HTML内容可以放在弹出窗口中,这将增加更多的可用性。
这是一个jsfiddle(我已经在jsfiddle中添加了用于外观的图像。更改它们并且你很高兴。)

为什么不使用像fancybox这样的插件?
