显示基于百分比的进度条是棘手的工作。如果您对此主题的了解有限,则显示装载状态或旋转图标会更好。

不是最漂亮的方法,但为我和其他许多人创造了奇迹。

CSS:

#uploadFrame { 
    height:1px; 
    width:1px; 
    visibility:hidden; 
} 

HTML:

// hide this on your page somewhere. It's only 1x1 pixels, so should be simple. 
<iframe src="zip_upload.php" name="uploadFrame" id="uploadFrame"></iframe> 

// your upload form 
<form enctype="multipart/form-data" method="post" action="zip_upload.php" target="uploadFrame"> 
    // form content 
</form> 

的jQuery:

$(form).submit(function() { 
    $('#loading-spinner').show(); 
}); 

$("#uploadFrame").load(function() { 
    $('#loading-spinner').hide(); 
}); 

当提交表单时,一显示加载图标,当上传和提取过程完成时(加载iFrame),加载图标消失。这一切都发生,无需重新加载页面。

使用它的好处是,如果稍加修改(将jQuery转换为Javascript),您不需要任何外部库或插件即可使用它。此外,这是非常简单和可以理解的。

ANOTHER OPTION ------------------------------------------- -

更高级一点,包含jQuery库&插件是必需的,但具有百分比功能。

检查出http://malsup.com/jquery/form/#file-upload的文档和完整的规范,这里演示:http://malsup.com/jquery/form/progress.html

下面是代码:

<form action="zip-upload.php" method="post" enctype="multipart/form-data"> 
    <input type="file" name="zip_file"> 
    <input type="submit" value="Upload"> 
</form> 

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.js"></script> 
<script src="http://malsup.github.com/jquery.form.js"></script> 
<script> 
(function() { 

var bar = $('.bar'); 
var percent = $('.percent'); 
var status = $('#status'); 

$('form').ajaxForm({ 
    beforeSend: function() { 
     status.empty(); 
     var percentVal = '0%'; 
     bar.width(percentVal) 
     percent.html(percentVal); 
    }, 
    uploadProgress: function(event, position, total, percentComplete) { 
     var percentVal = percentComplete + '%'; 
     bar.width(percentVal) 
     percent.html(percentVal); 
    }, 
    success: function() { 
     var percentVal = '100%'; 
     bar.width(percentVal) 
     percent.html(percentVal); 
    }, 
    complete: function(xhr) { 
     status.html(xhr.responseText); 
    } 
}); 

})();  
</script> 

而且你的PHP页面上:

<?php 
$target_path = "uploads/"; 
$target_path = $target_path . basename($_FILES['zip_file']['name']); 
if(move_uploaded_file($_FILES['zip_file']['tmp_name'], $target_path)) { 
    echo "The file ". basename($_FILES['zip_file']['name']). 
    " has been uploaded"; 
} else{ 
    echo "There was an error uploading the file, please try again!"; 
} 
?>
