使用jquery隐藏所有排序内容

Question

我试图在拖动或排序列表时仅隐藏所有内容。请帮我解决这个问题，这是我的working fiddle。这是我在小提琴中使用的jquery代码：

$( function() {
$( "#sortable" ).sortable();
$( "#sortable" ).disableSelection();
} );

提前致谢

使用启动和停止回调处理程序，您可以这样做。除了脚本之外，所有内容都与代码相同，只需看看脚本即可

/*$( function() {
    $( "#sortable" ).sortable({ 
         start: function (event, ui) {
            ui.item.find(".content").hide();
         },
         stop: function (event, ui) {
          ui.item.find(".content").show();
         }
    });
    $( "#sortable" ).disableSelection();
    
  } );*/ // this is to hide only dragging element content
  
 $( function() {
    $( "#sortable" ).sortable({ 
         start: function (event, ui) {
            $(".content").hide();
         },
         stop: function (event, ui) {
         $(".content").show();
         }
    });
    $( "#sortable" ).disableSelection();
    
  } ); // this is to hide all elements contents

#sortable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
  #sortable li { margin: 0 3px 3px 3px; padding: 0.4em; padding-left: 1.5em; font-size: 1.4em; height: 18px; }
  #sortable li span { position: absolute; margin-left: -1.3em; }
  h1{
    font-size:12px;
  }
  .content{
    font-size:10px;
  }

如果要在拖动时隐藏内容。

$( function() {
    $( "#sortable" ).sortable({
  start: function( event, ui ) {
    ui.item.find("div.content").hide();
  },
   stop: function( event, ui ) {
    ui.item.find("div.content").show();
  }
});
    $( "#sortable" ).disableSelection();


  } );
