一旦进度条达到100％，我希望在5秒后重新加载页面。

我已经有的代码：

我希望上传完成后整个页面重新加载，或者重定向到另一个URL，或者向用户发送警告消息。
再次感谢您对此的任何帮助...
更新： 我尝试编辑jquery.fileupload.js文件并添加了以下代码，但它不起作用或出现错误...
        // 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);

请编辑您的帖子，包括一个最小可重现示例，并限制您的问题以使其具体和清晰。 - vrintle
@compcobalt，我的答案有帮到您吗？是否需要更多的细节？我已经添加了一个像您要求的例子。 - Thatkookooguy

基本上，您需要强制重新加载页面。如果将相同的位置传递给 window.location.href ，它实际上不会导航。
我添加了一个最小工作示例，其中还有一个在2秒后更改的文本，这样我们就可以在片段中重新加载时看到文本恢复更改。
  1. 运行代码片段。
  2. 等待文本更改（2秒）
  3. 尝试上传文件
  4. 上传应该失败，因为URL不应该在StackOverflow上使用
  5. 您将看到警报，然后文本将恢复为原始文本，表示页面已重新加载

$(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缓存中重新加载，可以将 true 作为 location.reload 的第一个参数传递：
location.reload(true);

等待5秒后重新加载

您可以使用setTimeout来实现。将location.reload()替换为以下代码段：

setTimeout(() => location.reload(), 5000);
嗨，我尝试添加了那个但是没有任何反应...没有错误或其他任何提示。非常抱歉，你能否提供一个演示给我？我觉得我做错了什么。感谢你的帮助。 - compcobalt
@compcobalt 提供了一个可用的代码片段。如果这更清晰，请告诉我。 - Thatkookooguy

将 window.location.href 更改为相同的页面/ URL 不起作用。 请查看这里： window.location.href = window.location.href 和 window.location.reload() 之间的区别

而对于延迟，请使用setTimeout()

如果您确信“完成”函数确实有效，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);
},


此致敬礼，
