jQuery File Upload:如何动态更改上传 url

问题描述

我正在尝试在我的项目中使用 blueimp jQuery File Upload.它非常适合我的需求，但我需要在创建和配置插件后更改 url 文件动态上传.我做了很多调查，但不幸的是，没有发现任何有用的东西.一般来说，我有一个按钮来选择文件和覆盖实际上传的文件上传操作.基本创建如下所示:

I'm trying to use the blueimp jQuery File Upload in my project. It suits my needs fairly well but I need to change the url files are uploaded to dynamically after the plugin is created and configured. I've done a good deal of investigation, but, unfortunately, found nothing useful. In general, I have a button to choose files and fileupload action covering the actual upload. The basic creation looks like this:

 $('[upload-button]').fileupload(new FileUploadConfig())

以及配置本身:

 function FileUploadConfig() {

     // is set to a unique value for each file upload
     this.url = 'temporary';
     this.fileInput = $('[upload-button]');

     //... some other code
 }

我需要做的是更改此配置中的 url，然后调用 data.submit().我发现，这个配置是使用 $.data() 保存的，并试图用这样的代码解决问题

The thing I need to do is change the url in this config and then call data.submit(). I've found out, that this configuration is saved using $.data() and tried to solve the problem with such code

// get the current fileupload configuration
var config = $.data($('[upload-button]').get(0), 'fileupload');

// change the url configuration option
config.options.url = file.link;

//send a file
data.submit();

但是，这并不像我想要的那样工作.

However, this does not work the way I wanted.

关于如何实现这一点的任何想法?

Any ideas on how to accomplish this?

推荐答案

这里只是为了后代.

在当前 jQuery-upload rev 中，重写 add(evt,data) 函数并设置数据对象的 url 属性:

In the current jQuery-upload rev, override the add(evt,data) function and set the url property of the the data object:

fileupload({
   add: function(e, data) {
      data.url = 'customURL'
      ...
   },
   ...
}
