我希望整个页面重新加载一次，或者在上传完成后重定向到另一个 URL 或向用户发送警报消息。
再次感谢您对此提供的任何帮助...
更新：
我尝试编辑文件 jquery.fileupload.js 并添加了以下代码，但它不起作用或出错..
// Callback for successful uploads:
done: function (e, data)
alert("Upload Done");
window.location.href = "http://www.GOOD.com";
, // .bind('fileuploaddone', func);
// Callback for failed (abort or error) uploads:
fail: function (e, data)
alert("Upload FAILED");
window.location.href = "http://www.FAILED.com";
, // .bind('fileuploadfail', func);
【问题讨论】：
请编辑您的帖子，包括minimal, reproducible example 并限制您的问题，使其具体明确。 @compcobalt 我的回答有帮助吗？你需要更多细节吗？我添加了一个你问的例子 【参考方案1】：基本上，您需要强制重新加载。如果您将相同的位置传递给window.location.href，它实际上不会导航。
我添加了一个最小的工作示例，其中还有一个文本会在 2 秒后更改，因此我们可以看到在 sn-p 中发生重新加载时文本会变回。
-
运行代码sn-p
等待文本更改（2 秒）
尝试上传文件
上传应该失败，因为 URL 不应该在 *** 上工作
您会看到警报，然后文本将恢复为原始文本，表示页面重新加载
$(document).ready(() =>
// not needed! only here for the demo
setTimeout(() => $('#text').text('text changed after 2 seconds').addClass('changed'), 2000);
$('#fileupload').fileupload(
url: 'http://localhost:3000',
dataType: 'json',
done: function(e, data)
alert('success!');
location.reload();
,
fail: function(e, data)
alert('failure!');
location.reload();
,
progressall: function(e, data) /* ... */
);
);#text
padding: 0.5em;
.changed
color: red;

<!-- This will help us see the reload happening -->
<div id="text">page initial load!</div>
<input id="fileupload" type="file" name="files[]" multiple>如果您想确保从服务器而不是浏览器的缓存重新加载，请将true 作为location.reload 的第一个参数传递：
location.reload(true);
等待 5 秒再重新加载
您可以使用setTimeout 来做到这一点。用以下 sn-p 替换 location.reload()：
setTimeout(() => location.reload(), 5000);
【讨论】：
嗨，我尝试添加，但没有任何反应.. 没有错误或任何东西。很抱歉，如果你给我一个演示可以吗？我想我做错了什么。感谢您的帮助。 @compcobalt 提供了一个有效的 sn-p。让我知道这是否更清楚。【参考方案2】：将window.location.href 更改为相同的页面/url 将不起作用。
看这里：Difference between window.location.href=window.location.href and window.location.reload()
对于延迟，请使用 setTimeout()
如果您确定“完成”功能确实有效，请更改为
done: function (e, data)
alert("Upload Done");
var delayInMilliseconds = 5000; //5 seconds
setTimeout(function()
location.reload(); //use 'location.reload(true);' if you want to force reload from server
, delayInMilliseconds);
,
最好的问候，
婆罗门
