javascript - 如何触发 Uploadify onError 事件处理程序？

Question

我正在使用 Uploadify上传文件。问题是，我需要在处理这些文件期间通知用户任何错误。

Uploadify 有 onError、onComplete 和 onAllComplete 事件处理程序，但我不知道如何触发这些事件以便通知用户发生了什么事。

我需要发送 JSON 字符串吗？有线索here和 here和 here但我无法让它工作。也许论坛上的帖子已经过时了。

有人有适用于 Uploadify 2.1 的示例吗？

Answer 1

onError 进入 uploadify 的选项:

$("#fileInput").uploadify({
  onError: function(e, q, f, o) {
    alert("ERROR: " + o.info);
  }
});

Four arguments are sent to the function:

• event: The event object.
• queueID: The unique identifier of the file that returned an error.
• fileObj: An object containing details about the file that was selected.
  • name – The name of the file

  • creationDate – The date the file was created
  • modificationDate – The last date the file was modified
  • type – The file extension beginning with a ‘.’
• errorObj: An object containing details about the error returned.
  • type – Either ‘HTTP’, ‘IO’, or ‘Security’
  • info – An error message describing the type of error returned
