Question

当我向队列添加文件时，我为每个文件生成一个文本输入。

是否可以将此输入值发送到服务器端？

我尝试将值添加到params对象中，如下所示：

up._options.request.params.description = id;

但它只发送最后一张图片的ID。

var up = new qq.FineUploaderBasic({
    button: document.getElementById("addFiles"),
    request: {
        params: {
            action: "upload",
        },
        endpoint: config.uploadURL,
    },
    validation: {
        allowedExtensions: ["jpg", "jpeg", "png", "gif", "mkv", "mp4"],
    },
    autoUpload: false,
    callbacks: {
        onSubmit: function(id, fileName, response) {
            var element = document.createElement("li");
            element.setAttribute("id", "qImage-"+id);
            element.setAttribute("class", "qImage");
            $(".imagesList").prepend(element);

            var out  = "<div class='fileInfo'>";
                out += "<span id='qCancel-"+id+"'>Cancel </span>";
                out += fileName;
                out += "</div>";
                out += "<div class='fileData'>";
                out += "<label for='fileDescription'>Description</label>";
                out += "<input type='text' name='fileDescription' id='fileDescription'>";
                out += "</div>";

            $("#qImage-"+id).html(out);

            $("#qCancel-"+id).on("click", function(){
                up.cancel(id);
                $("#qImage-"+id).remove();
            });
            up._options.request.params.description = id;
        },
    }
});
$('#startUpload').on("click", function(){
    up.uploadStoredFiles();
    //document.getElementById('queue-list').innerHTML = '';
});

$('#cancelUpload').on("click", function(){
    up.cancelAll();
});

为了扩展Ray的评论，我知道有两种方法。第一个可能是S3实现独有的，但我使用：

@Override
    protected void onPostExecute(String result) {

        if (result != null && !result.equals("")) {

            try {
                JSONArray jArray = new JSONArray();
                JSONObject jObject = null;
                try {
                    jObject = new JSONObject(result);
                } catch (JSONException e) {
                    e.printStackTrace();
                }

                Iterator x = jObject.keys();
                while (x.hasNext()){
                    String key = (String) x.next();
                    jArray.put(jObject.get(key));
                }

                for (int i = 0; i < jArray.length(); i++) {

                    JSONObject jRes = jArray.getJSONObject(i);

                    String title = jRes.getString("title");
                    Log.d("Article_title", title);

                }
                this.progressDialog.dismiss();
            } catch (JSONException e) {
                Log.e("JSONException", "Error: " + e.toString());
            }
        }
    }

如果您希望将setParams与文件上传请求一起发送，请使用setParams。

从onSubmit回调生成的输入发送值
