JQuery Animate Z-Index？

Question

在我的页面中,我有不同的菜单项,可以触发不同的相应图片.将z-index相应的图片切换到顶部.这是代码:

$(document).ready(function(){

var doorOpen = false;

$("a[href=#andrew]").click(function() {

    if (doorOpen) { // set animation duration for door close, based on actually needed to animate the door closed or not
        var duration = 1500;
    } else {
        var duration = 0;
    }

    $("#rightdoor,#leftdoor").animate(
        {"marginLeft":"0px"},
        {duration:duration,
            complete:function() {
                $('.pic2 .pic3 .pic4 .pic5').css('zIndex', 1);  //puts wrong pics in back
                $('.pic1').css('zIndex', 2);  //brings right pic into view
                $('#rightdoor').animate({  //opens doors again
                 marginLeft: "150px",
                }, 1500);
                $('#leftdoor').animate({
                 marginLeft: "-150px",
                }, 1500);
            }
        }
    );

    doorOpen = true;


});

$("a[href=#bugz]").click(function() {

    if (doorOpen) { // set animation duration for door close, based on actually needed to animate the door closed or not
        var duration = 1500;
    } else {
        var duration = 0;
    }

    $("#rightdoor,#leftdoor").animate(
        {"marginLeft":"0px"},
        {duration:duration,
            complete:function() {
                $('.pic1 .pic3 .pic4 .pic5').css('zIndex', 1);  //puts wrong pics in back
                $('.pic2').css('zIndex', 2);  //brings right pic into view
                $('#rightdoor').animate({  //opens doors again
                 marginLeft: "150px",
                }, 1500);
                $('#leftdoor').animate({
                 marginLeft: "-150px",
                }, 1500);
            }
        }
    );

    doorOpen = true;    
});
});

问题是,z-index每个菜单项似乎只有一次工作.如果你最初点击#andrew,它会将pic1带到顶部,如果你点击#bugz它会将pic2带到顶部.但是,如果#andrew再次单击它会在.css(z-index)更改之前和之后为代码设置动画,但不会更改z-index以使pic1返回到顶部.

我是Javascript/JQuery的新手所以请原谅我,如果我遗漏了一些明显的东西

你的选择器是错误的:$('.pic2 .pic3 .pic4 .pic5')寻找的后代.pic2.

您可以使用逗号分隔这些类而不是空格,但使用该.siblings方法更简单:

$('.pic1').css('zindex',2).siblings().css('zindex',1);
