我为它制作了一个上传页面和 php 脚本，它是一个 AJAX 脚本，但是我在 Firebug 中遇到了一些错误，并且我的上传百分比没有被返回，到目前为止，我只能在 firefox 中进行一次上传，并且脚本赢了甚至不能在 chrome 中工作。

Firebug 中的错误

这是我的代码：

<?php 
    session_start();
    include ('../Connect/Connect.php');
    $User = $_SESSION['User'];

    if(isset($User))
    {
    }
    else 
    {
        header("location:../");
    }
    $Connect -> close();
?>

Document.getElementById需要ID的物理字符串，你不需要指定它是一个ID。

您正在混淆 javascript 和 jQuery。在 jQuery 中，它$.("#Progress")会起作用，因为该$函数不知道您是在寻找一个 ID 还是一个类。

这个：

Progress = document.getElementById('#Progress');

应该是这样的：

Progress = document.getElementById('Progress');

或这个：

Progress = $("#Progress");
