有个显示层，z-index已经很大了，可是下拉菜单还是在它之上，谁能帮忙解答啊？下拉菜单的z-index负值也不

Answer 1

我以前也经常遇到这个问题，后来我直接用js给每个div加上z-index,就不会出现这个问题了，呵呵……
给你个jquery的代码做这件事的。

//This code will start with a z-index of 10000, and decrement the z-index for each DIV element of the page by 10, giving the first DIV a z-index of 10000, the second, 9990, the third 9980, and so on. Notice that the selector will find all DIV elements with the code "$('div')", using the same syntax as CSS selectors.
$(function() {
var zIndexNumber = 10000;
$('div').each(function() {
$(this).css('zIndex', zIndexNumber);
zIndexNumber -= 10;
});
});
