z索引无法在Chrome浏览器中使用？

Question

z-index无法在Chrome浏览器中运行，它会弹出容器后面。如果我更改菜单的z-index，则“链接按钮”可以单击。

$(function() {
      $('.ui-323 ul.ui-nav > li').tooltip();
    });

    $(document).ready(function() {

      $(".ui-323 ul.ui-nav > li > a").click(function(e) {
        e.preventDefault();
        if (!($(this).parents(".ui-323").hasClass("active"))) {
          //$(this).parents(".ui-323").addClass("active");		//Add Class Active
        } else {
          $(this).parents(".ui-323").removeClass("active"); //Remove Class Active
        }
      });

      $(".ui-323 ul.ui-nav > li > a").mouseleave(function(e) {
        e.preventDefault();
        $(this).parents(".ui-323").addClass("active");
      });
    });

Answer 1

试试这个：

.tab-content{
    z-index: 999;
    position: absolute; /*position has to be absolute*/
}

Answer 2

您的父容器.ui-323的位置为：fixed和z-index：auto（默认情况下） ＆安培; child .tab-content有z-index：999;哪个不行。

你应该给.ui-323 z-index：-1; ＆安培; child z-index：1;使它工作。

Answer 3

只需将z-index提交给.ui-323即可。

因为.tab-content的父容器position:fixed需要比z-index更高的bg_ctr类才能显示在顶部。

.ui-323{
    max-width: 310px;
    margin: 40px auto;
    padding:0px 20px;
    overflow: hidden;
  z-index:1; // Here given z-index
}

要解决链接可点击问题，请添加以下css：

.ui-323.active{
    z-index:-1;
}

Answer 4

您只需在正确的元素上放置正确的位置和z-index。

我假设您希望左子菜单（.ui-323）超过其他元素：

.ui-323 {
  z-index: 10;
}
