dropzone.js - 上传所有文件后如何做某事 [英] dropzone.js - how to do something after ALL files are uploaded

问题描述

我使用dropzone.js作为拖放文件上传解决方案。在所有上传文件后，我遇到了需要调用函数的问题。在这种情况下，

I am using dropzone.js for my drag-drop file upload solution. I am stuck at something where I need to call a function after all the files are uploaded. In this case,

Dropzone.options.filedrop = {
    maxFilesize: 4096,
    init: function () {
        this.on("complete", function (file) {
            doSomething();
        });
    }
};

将为每个已上传的文件调用doSomething（）。如何在上传所有文件后调用函数？

doSomething() will be called for each file that has been uploaded. How can I call a function after all the files are uploaded?

推荐答案

编辑：现在有了您可以使用的 queuecomplete 活动正是出于这个目的。

There is now a queuecomplete event that you can use for exactly that purpose.

上一个答案：

Paul B.的回答有效，但更简单的方法是检查是否队列中仍有文件或文件完成时上传。这样您就不必自己跟踪文件：

Paul B.'s answer works, but an easier way to do so, is by checking if there are still files in the queue or uploading whenever a file completes. This way you don't have to keep track of the files yourself:

Dropzone.options.filedrop = {
  init: function () {
    this.on("complete", function (file) {
      if (this.getUploadingFiles().length === 0 && this.getQueuedFiles().length === 0) {
        doSomething();
      }
    });
  }
};
