<div class="main">

      Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. 
     </div> 
    </div> 
    <button class="addDiv">Add open Div</button> 
</div> 

Jetzt bin ich Anfügen der neuen div mit folgenden Code

         typesetting industry. Lorem Ipsum has been the industrys \n\ 
         standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type \n\ 
         specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining \n\ 
         essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, \n\ 
         and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</div>'; 
       $('.user').append(html); 
      }); 
     });

$(".open_div").animate({height:0},1500); 

Aber seine nicht funktioniert well.Can Sie mir vorschlagen, was ich tue falsch.

Answer 1

Hier ist eine Implementierung, die die Funktionen jQuery slideUp und slideDown verwendet. Ich entferne die Divs, die hochgeschoben sind. Höhe: 100% ist manchmal das Problem mit der Animation.

let counter = 0; 
 

 
$('.addDiv').click(function() { 
 
    var html = $('<div class="closed_div">Lorem Ipsum is simply dummy text of the printing and \n\ 
 
         typesetting industry. Lorem Ipsum has been the industrys \n\ 
 
         standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type \n\ 
 
         specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining \n\ 
 
         essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, \n\ 
 
         and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.' + counter++ + '</div>'); 
 
    $('.user div').slideUp(300, function() { 
 
    $(this).remove(); 
 
    });    
 
    $('.user').append(html); 
 
    html.slideDown(); 
 
    
 
});

.closed_div { 
 
    display: none; 
 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<div class="main"> 
 
    <div class="user"> 
 
    <div class="open_div" style="display:none;">

$(".closed_div").animate({height:'100%','opacity':1},1500); 
 
    $(function() {

    }); 
 
});

    <button class="addDiv">Add open Div</button> 
 
</div>

Answer 3

Sie benötigen Anzeige keine Eigenschaft auf den neu open_div beigefügten einzustellen, fügen Sie closed_div Klasse mit der zuletzt geöffneten div. Verstecken Sie dann das letzte closed_div mit slideUp. Innerhalb des Rückrufs des SlideUp, slideDown der letzte open_div.

Und in Ihrem CSS, müssen Sie display: none Eigenschaft open_div

$(document).ready(function(){ 
 
      $('.addDiv').click(function(){ 
 
       var html = '<div class="open_div">Lorem Ipsum is simply dummy text of the printing and \n\ 
 
         typesetting industry. Lorem Ipsum has been the industrys \n\

         and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</div>'; 
 
       $('.open_div:last').addClass('closed_div'); 
 
       $('.user').append(html); 
 
       $('.closed_div:last').slideUp("slow", function() { 
 
       \t $('.open_div:last').slideDown("slow"); 
 
       }); 
 
      }); 
 
     });

.open_div { 
 
    display: none; 
 
}
