Plupload在添加文件时自动开始上传

Question

添加文件后,我想自动开始上传过程.我在FilesAdded结束时调用了start函数,但它没有启动上传.

uploader.bind('FilesAdded', function(up, files) {
      var str = "";
      for (var i in files) {
        str += '<div id="' + files[i].id + '">' + files[i].name + ' (' + plupload.formatSize(files[i].size) + ') <b></b></div>';
      }
      $('#filelist').html(str);
      up.refresh();
      up.start();
    });

这是我的创作代码

var uploader = new plupload.Uploader({
      runtimes: 'html5,flash,silverlight',
      autostart : true,
      url: '<%= images_path %>',
      max_file_size: '10mb',
      multipart: true,
      browse_button: "pickfiles",
      container: "the-uploader",
      drop_element : "drop-area",  
      multipart_params: {
        '_http_accept': 'application/javascript',
        '<%=request_forgery_protection_token%>': '<%=form_authenticity_token%>',
        '<%=request.session_options[:key]%>': '<%=request.session_options[:id]%>'
      },
      filters: [
        {title: "Images", extensions: "avi,jpg,jpeg,png,zip"}
      ],
    });

添加up.start()FileAdded绑定应该在添加文件时开始上传.我已经按照这样的方式调用我的上传器(我在尝试调用它时遇到了问题):

$(function() {
    // Setup html5 version
    $("#html5_uploader").pluploadQueue({
      // General settings
      runtimes : 'html5',
      url : 'upload.php',
      max_file_size : '10mb',
      chunk_size : '1mb',
      unique_names : true,
      dragdrop : true,
      multiple_queues : false,
      multi_selection : false,
      max_file_count : 1,

      // Specify what files to browse for
      filters : [
        {title : "Text files", extensions : "txt"}
      ],

      init : {
        FilesAdded: function(up, files) {
          up.start();
        },
        UploadComplete: function(up, files) {
          $.each(files, function(i, file) {
            // Do stuff with the file. There will only be one file as it uploaded straight after adding!
          });
        }
      }
    });
  });

"确保在init之后绑定它,因为它绑定了默认处理程序."

所以你的代码:

uploader.bind('FilesAdded', function(up, files) {...});

在你之后

uploader.init();

对我来说,它不适用于您的版本,但确实有效:

FilesAdded: function(up, files) {
   setTimeout(function () { up.start(); }, 100);
 },

因此,在100 ms后设置一个定时器来执行启动.我在测试时使用了jquery ui版本并得到了这个错误:

g("#" + l.id).position() is null
