Question

我有一个JQuery下拉列表，它隐藏在J here下面的JQuery幻灯片后面。

我需要将下拉列表放在首位...我已经尝试过z-index无效。

从我从研究中看到的这是一个相当普遍的问题......任何人都可以帮忙吗？

代码：

#nav {
width:800px;
margin:0px auto 0px;
height:25px;
}

#nav ul {
height:25px;
margin:0 0px 0 0;
padding:0;
list-style:none;
}

#nav ul li {
background:#76bf43;
padding:5px 0px 0px 0px;
margin:0 10px 0 0;
color:#ffffff;
border-top-left-radius: 5px;
border-top-right-radius: 5px;
width:100px;
text-align:center;
height:20px;
float:left;
}

#nav ul li:hover {
cursor:pointer;
}

#nav ul li ul {
margin:0;
padding:0;
}

#nav ul li ul li {
padding:0;
margin:0;
border-top-left-radius: 0px;
border-top-right-radius: 0px;
height:25px;
}

$(document).ready(function(){

//This keeps track of the slideshow's current location
var current_panel = 1;
//Controlling the duration of animation by variable will simplify changes
var animation_duration = 2500;

$.timer(6000, function (timer) {
    //Determine the current location, and transition to next panel
    switch(current_panel){
        case 1:
            $("#slideshow").stop().animate({left: "-800px", top: "0px"}, {easing: 'easeOutBack', duration: animation_duration});
            current_panel = 2;
        break;
        case 2:
            $("#slideshow").stop().animate({left: "0px", top: "-210px"}, {easing: 'easeOutBack', duration: animation_duration});
            current_panel = 3;
        break;
        case 3:
            $("#slideshow").stop().animate({left: "-800px", top: "-210px"}, {easing: 'easeOutBack', duration: animation_duration});
            current_panel = 4;
        break;
        case 4:
            $("#slideshow").stop().animate({left: "0px", top: "0px"}, {easing: 'easeOutBack', duration: animation_duration});
            current_panel = 1;
        break;
        timer.reset(12000);
    }
});

});
</script>

Answer 1

我只能猜测你在错误的元素上尝试z-index。放手一搏。

#nav {
    position: relative;
    z-index: 40000;
}

您应该会发现这将解决您的问题。

Answer 2

#nav ul添加position:relative;z-index:1;

z-index始终适用于定位元素，因为css文档告知我们。
