图片上传后调用javascript函数

Question

java脚本函数，我希望它在上传图像并在数据库中完成新值后显示。 整个页面代码是这样的：

        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>

        <style type="text/css">
        body
        {
            font-family: Helvetica, Arial;
        }

        .backdrop
        {
            position:absolute;
            top:0px;
            left:0px;
            width:100%;
            height:100%;
            background:#000;
            opacity: .0;
            filter:alpha(opacity=0);
            z-index:50;
            display:none;
        }


        .box
        {
            position:absolute;
            top:20%;
            left:30%;
            width:500px;
            height:300px;
            background:#ffffff;
            z-index:51;
            padding:10px;
            -webkit-border-radius: 5px;
            -moz-border-radius: 5px;
            border-radius: 5px;
            -moz-box-shadow:0px 0px 5px #444444;
            -webkit-box-shadow:0px 0px 5px #444444;
            box-shadow:0px 0px 5px #444444;
            display:none;
        }

        .close
        {
            float:right;
            margin-right:6px;
            cursor:pointer;
        }

        </style>

            <script type="text/javascript">

            $(document).ready(function(){

                $('.lightbox').click(function(){

                    $('.backdrop, .box').animate({'opacity':'.50'}, 300, 'linear');
                    $('.box').animate({'opacity':'1.00'}, 300, 'linear');
                    $('.backdrop, .box').css('display', 'block');
                });

                $('.close').click(function(){
                    close_box();
                });

                $('.backdrop').click(function(){
                    close_box();
                });

            });


            function close_box()
            {
                $('.backdrop, .box').animate({'opacity':'0'}, 300, 'linear', function(){
                    $('.backdrop, .box').css('display', 'none');
                });
            }

        </script>

    <!-- <a href="#" class="lightbox">Open Lightbox</a> -->

    <div class="backdrop"></div>
    <div class="box" style="margin: 0 auto; width:100%; height:400px;">

    </div>

<div class="widget">

                } else {
                    $allowed = array('jpg', 'jpeg', 'gif', 'png');

                    $file_name = $_FILES['profile']['name'];
                    $file_extn = strtolower(end(explode('.', $file_name)));
                    $file_temp = $_FILES['profile']['tmp_name'];
                    // u can put one for file size here

                    if (in_array($file_extn, $allowed) === true) {
                        change_profile_image($session_user_id, $file_temp, $file_extn);
                        //header('Location: ' . $current_file);

                        exit();
                    } else {
                        echo 'Incorrect file type. Allowed: ';
                        echo implode(', ', $allowed);
                    }
                }
            }

                if (empty($user_data['profile']) === false){
                    echo '<img src="', $user_data['profile'], '" alt="', $user_data['first_name'] , '\'s Profile Image">';
                }
            ?>
            <iframe id="myIframe" name="myIframe" width="0" height="0" frameborder="0"></iframe>
            <form action="" method="post" enctype="multipart/form-data" target="myIframe" >
            <input type="file" name="profile"> <input type="submit" class="lightbox">
            </form>

        </div>
        <ul>
        <li>
            <a href="logout.php">Log out</a>
        </li>
        <li>
            <a href="<?php echo $user_data['username']; ?>">Profile</a>
        </li>
        <li>
            <a href="changepassword.php">Change password</a>
        </li>
        <li>
            <a href="settings.php">Settings</a>
        </li>
        </ul>
        </div>
</div>

java脚本函数：

$(document).ready(function(){

                $('.lightbox').click(function(){

                    $('.backdrop, .box').animate({'opacity':'.50'}, 300, 'linear');
                    $('.box').animate({'opacity':'1.00'}, 300, 'linear');
                    $('.backdrop, .box').css('display', 'block');
                });

                $('.close').click(function(){
                    close_box();
                });

                $('.backdrop').click(function(){
                    close_box();
                });

            });

在上传代码后显示：

if (in_array($file_extn, $allowed) === true) { change_profile_image($session_user_id, $file_temp, $file_extn);
