Question

我在触发uploader.start（）时遇到问题，如果没有单击启动按钮进行文件上传，我使用的是最新版本的Plupload。这里是完整的代码，我想找到为提交点击上传的每个文件给出的临时名称，这样我就可以转到服务器并使用引用ID重命名文件，这样可以很容易地识别属于的文件。 / p>

首先，您应该在$（document）.ready中移动提交绑定，以确保DOM已准备好进行提交绑定。

我猜你应该尝试依赖一个闭包来确保在StateChanged中正确绑定“uploader”（你也可以用var uploader = $（“＃Testloader”）开始你的StateChanged Handler .pluploadQueue（）;）：

  $('form').submit(function (e) {
      alert("clicked me");
      var uploader = $("#Testloader").pluploadQueue();
      // Files in queue upload them first
      if (uploader.files.length > 0) {
          // When all files are uploaded submit form
          uploader.bind('StateChanged', (function(closedUploader){return function () {
              if (closedUploader.files.length === (closedUploader.total.uploaded + closedUploader.total.failed)) {
                  // $('form')[0].submit();
                  alert("Form submitted");
              }
          };})(uploader)
          );
          uploader.start();

      } else {

          alert('You must queue at least one file.');

      }
      return false;
  });

希望这会有所帮助
