如何在上载完成时使用Plupload通过Ajax返回数据? [英] How do I return data via Ajax using Plupload on Upload Complete?

问题描述

最近几个小时，我一直在尝试获取某些东西……在完成队列后，从pluploader找回来的东西仍然无济于事.

I've been trying for the last few hours to get something... anything back from the pluploader upon completion of the queue to no avail.

这是我的JS代码:

var uploader = $('#pluploadDiv').pluploadBootstrap();

uploader.bind("UploadComplete", function(up, files) {
    var obj = $.parseJSON(response.response);
    alert(obj.result);

});

在upload.php脚本的最后一行，我有:

On the very last line of the upload.php script, I have:

die('{"jsonrpc" : "2.0", "result" : "'.$_REQUEST['unitID'].'", "id" : "id"}');

这对我来说很有意义...但是它无法正常工作，文件上传没有问题，但是警报甚至没有触发...没有任何响应.

This makes sense to me... but it's not working, the files upload without problems, but the alert doesn't even fire off... there is no response whatsoever.

有想法吗?

使用新代码作为解决方案进行编辑

我正在使用的JS(感谢jbl):

The JS that I'm using (thanks jbl):

var uploader = $('#pluploadDiv').pluploadBootstrap();

uploader.bind('FileUploaded', function(upldr, file, object) {
    var myData;
    try {
        myData = eval(object.response);
    } catch(err) {
        myData = eval('(' + object.response + ')');
    }
    $("#vehicle_id_value").val(myData.result);
});

Upload.php脚本保持不变，最后一行代码:

Upload.php script stayed the same, last line of code:

die('{"jsonrpc" : "2.0", "result" : "'.$_REQUEST['unitID'].'", "id" : "id"}');

因此，基本上，当我创建外壳行以在上传脚本中将图像与之关联时，我会通过绑定到plupload对象的FileUploaded事件将行ID传递回原始表单到一个隐藏的输入字段中.

So basically when I create the shell row to associate images to in the upload script, I pass the row ID back to the original form into a hidden input field via the FileUploaded event that is bound to the plupload object.

<input type="hidden" name="vehicle_id_value" id="vehicle_id_value" value="" />

像魅力一样工作！

推荐答案

在上传过程中，可能已经上传了几个文件.在UploadComplete阶段，个人响应不再可用. 如果要显示有关特定文件上载的信息，则应绑定到FileUploaded事件而不是UploadComplete. 像这样的东西:

Several files could have been uploaded as part of the upload process. The individuals responses are not avalaible anymore when on UploadComplete stage. If you want to display info about a specific file upload, you should bind to the FileUploaded event instead of UploadComplete. Something like :

uploader.bind('FileUploaded', function(upldr, file, object) {
    var myData;
    try {
        myData = eval(object.response);
    } catch(err) {
        myData = eval('(' + object.response + ')');
    }
    alert(myData.result);
});
