javascript - 删除溢出类时在标题上制作 slideDown()

Question

我有一个弹出窗口，在单击时会滑入 View 。我制作标题的方式是使用以下 css:

.ellipsis {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
  -o-text-overflow: ellipsis;
}

我使用 jQuery 根据点击添加/删除。
但是当ellipsis 类被移除时，标题只是“POPS”进入 View 。

所以我的问题是:是否可以使用 jquery 或 css 简化从 hidden 到 not 的转换？

检查这个

 $(document).ready(function(){
       
      
 var havePoppedUp = 0;      
 $(window).on('scroll', function() {
   var st = $(this).scrollTop();
   var wh = $(document).height() - $(window).height();
   var perc = (st*100)/wh;
   
   if(perc > 50 && havePoppedUp == 0)
       {
           havePoppedUp = 1;
            $(".popupContent").css("display", "inline");
            $('.popupHeader h7').removeClass("ellipsis");  
           
       }
});


    $(".closepopup").click(function(){
        $(".popupContainer").fadeOut()
    });
      
    $(".closepopupBtn").click(function(){
        $(".popupContainer").hide()
    });


    $(".popupHeader").click(function(){
        if($('.popupContent:visible').length == 0)
            {
            $(".popupContent").slideDown(600);
           $('.popupHeader p').toggleClass( "ellipsis", 600 );
            }
        else {
            
            $(".popupContent").slideUp(600);
            $('.popupHeader p').toggleClass( "ellipsis", 600 );
            
        }    
            
    });        
                
});

.popupContainer {
    padding: 5px 15px 0 15px;
    position: fixed; 
    background-color: #718F97;
    bottom: 0;
    right: 50px;
    max-width: 300px;
    color: white;

}
.popupHeader {
    width: 100%;
    height: auto;
}
.popupHeader p {
    max-width: 85%;
    float: left;
    margin-bottom: 5px;
}

.ellipsis {
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
    -o-text-overflow: ellipsis;
}

.popupHeader button {
    float: right;
    text-decoration: none;
    border: none;
    background-color: #718F97;
    color: white;
    margin-bottom: 5px;
}

.popupContent {
    display: none; 
}

.popupContent p {
    max-width: 100%;
    clear: both;
}

.popupContent button {
    width: 100%;
    margin-bottom: 10px;
}
