jQuery appendTo DIV然后动画

当我按下“new”按钮启动jQuery动作时：

1.)创建DIV并将addClass“block”创建到DIV

2.)appendTo“.container”

3.)将容器中的DIV从不透明度0设置为1

JsFiddle Example

HTML

<div class="panel">
   <button class='new'> + </button>
</div>
<div class="container">
</div>

CSS

.block {
   margin: 0px;
   width: 200px;
   display: inline-block;
   border-right:thin dashed #aaa;
   opacity: 0;
}
.panel {
   position: absolute;
   top: 100px;
   padding: 5px;
   color: #FFF;
   font-size: 15px;
   background: #d30;
   height: 30px;
   cursor:pointer;
}
.container {
   position: absolute;
   top: 145px;
   left: 0px;
}
button{
   font-size: 20px;
   padding: 0px;
}

jQuery的

function createChatBox(title) {
   $(" <div />" ).attr("id","block_"+title)
    .addClass("block")
    .html('<div class="title">text1 '+title+'</div>')
    .appendTo($( ".container",{
        css: {
            display: 'inline-block',opacity: 0
        }
    }).animate({ opacity: 1  }) );
}

$(".new").click(function(){
     createChatBox('text2');
 });

解决方法

您需要将appendTo部分更改为：

.appendTo(".container",opacity: 0
        }
    }).animate({ opacity: 1  });
