使用jquery淡出div

Question

我有问题我使用bootstrap（模态）来显示我的表单。我想要做的是当我提交addemployee div时，调用（result）会出现消息。 我想要做的是课后结果出现我想在5s后做出淡出; 这是我的源代码

<div id="content">
                <div class="container">
                    <div class="data">
                       <?php
                                                 if(isset($_POST['addemployee'])){
                                                    //collect data
                                                    $name=$_POST['name'];
                                                    $salary=$_POST['salary'];
                                                    if($name== null){
                                                        echo ' <div class="result btn-success "><span class="center-block"> please insert the value of name </span></div>';
                                                     }elseif (is_numeric($name)) {
                                                        echo ' <div class="result btn-success "><span class="center-block">the value of name must be acharacter </span></div>';  

                                                     }elseif (strlen($name)>20) {
