javascript - 一段时间后消息消失

Question

对于其中一个项目，我准备了一个 HTML 表单并且代码运行良好。我需要的是错误或成功消息应在几秒钟后消失。任何机构都可以帮助我更正代码。代码如下。

HTML 格式

<div class="form">
<form id="form" name="form" method="post" action="  ">
<div id="fc">
<div id="error"></div>
<label>Name: </label>
<input type="text" name="name" id="name" />
<label>Place: </label>
<input type="text" name="name" id="place" />
</div>
<div id="btn">
<input type="submit" id="submit" value="SUBMIT" onClick="Submit(event)" />
</div>
</form>
</div>

CSS 代码

.form{ margin:0 auto;width:280px;
         padding:10px;border:solid 2px #b7ddf2;
         background:#f5fffa;
         }
   #fc{
         font-family:"Lucida Grande", "Lucida Sans Unicode", 
         Verdana, Arial, Helvetica, sans-serif; font-size:12px;
         }

   #fc label{display:block;font-weight:bold;
         text-align:right; width:120px;float:left;
         font-size:14px;
         }

   #fc input{float:left;font-size:12px;
         padding:3px 3px; border:solid 1px #aacfe4;
         width:130px; margin:2px 0 10px 10px;
         }

   #btn{clear:both;font-size:13px;font-weight:bold;
         text-align:center; margin-bottom: 2px;
         }
#error{  font-weight:bold;
         text-align:left; 
         height: 20px;
         color: red;font-size:15px;
         }

JS 代码

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

<script>
function Submit(e){
    e.preventDefault();

    var name       = $("#name").val();
    var place      = $("#place").val();

       if($("#name").val() == "" ){
            $("#name").focus();
                $("#error").html("Enter the Name.");
                return false;
        }
        else if($("#place").val() == "" ){
                $("#place").focus();
                $("#error").html("Enter the Place.");
                return false;
        }

                else if($(name != '' && place != '' )){
                $("#error").html("Form submitted successfully.")
                $("#form")[0].reset();

              // Returns successful data to php.
               $.post(" ", {name: name, place: place}, 
             function(data) 
                {
                        $("#form").append(data); 
                    });
              }
     }
</script>

添加:

setTimeout(function(){
    $('#error').hide()
}, 3000) // time in millisecond for as long as you like
