我试图隐藏并显示页脚导航栏,但是我想更改人字形图标,当导航栏隐藏时人字形向上显示,当导航栏显示人字形向下显示时,因此我尝试删除类.bottom-action并添加一个类.bottom-action2并单击第二个按钮时,将所有设置反向,但无法正常工作。


$(document).ready(function(){
    $(".bottom-action").click(function(){
        $(".bottom-navbar").slideToggle("slow");
       $(".down").css("display","none");
       $(".up").css("display","block");
       $(".bottom-action").removeClass('bottom-action').addClass("bottom-action2");

    });

$(".bottom-action2").click(function(){
        $(".bottom-navbar").slideToggle("slow");
       $(".up").css("display","none");
       $(".down").css("display","block");
       $(".bottom-action2").removeClass('bottom-action2').addClass("bottom-action");

    });



});

.bottom-navbar{
  position: fixed;
width: 100%;
bottom: 0px;
left: 0px;
background: #E4E4E4;
padding-top: 3px;
border-top: 1px solid #C9C9C9;
z-index: 7000;
}

.bottom-navbar .item{

  margin-left: 22px;
margin-right: 22px;
display: inline-block;
border-bottom: 2px solid transparent;
cursor: pointer;
}

.bottom-action{position: fixed;
bottom: 0px;
right: 10%;
background-color: #EEE;
color: #000;
z-index: 7002;
background: transparent;

}

.bottom-action2{position: fixed;
bottom: 0px;
right: 10%;
background-color: #EEE;
color: #000;
z-index: 7002;
background: transparent;

}

.bottom-action .down{}
.bottom-action .up{display: none;}

<div class='bottom-action'><span class='glyphicon glyphicon-chevron-down down'></span> <span class='glyphicon glyphicon-chevron-up up'></span></div>

最佳答案

尝试:

$(document).on('click', '#myButton', function(e){
    //jour code
});


代替 :

$('myButton').click(...)
