jQuery-File-Upload 完成回调

Question

我正在尝试使用 blueimp 的文件上传，并且 - 像很多人一样 - 我不明白为什么 done 回调不起作用！

即使失败回调发送失败问题，文件上传也能正常工作（我使用 php 上传处理程序）。我已经阅读了很多关于 json 问题的主题，但没有适合我的问题的答案。

这是我的 javascript 代码：

$(function () {
'use strict';
var url = 'server/php/';
$('#fileupload').fileupload({
    url: url,
    dataType: 'json',
    done: function (e, data) {
        $.each(data.result.files, function (index, file) {
            $('<p/>').text(file.name).appendTo('#files');
        });
    },
    fail: function (data) {
        alert("Fail!");
    },
    progressall: function (e, data) {
        var progress = parseInt(data.loaded / data.total * 100, 10);
        $('#progress .progress-bar').css(
            'width',
            progress + '%'
        );
    }
}).prop('disabled', !$.support.fileInput)
    .parent().addClass($.support.fileInput ? undefined : 'disabled');
});

您有解决方案或进行测试以发现一些错误吗？

EDIT1：成功回调仅在我使用dataType: 'text'时有效

EDIT2：这是触发完成回调时的响应：

Answer 1

删除“dataType: 'json'”行，并在“done”回调中将“data.result.files”更改为“data.files”即可！

dataType: 'json',
        done: function (e, data) {
            $.each(data.files, function (index, file) {
                $('<p/>').text(file.name).appendTo('#files');
            });
        },

Answer 2

尝试将完成移动到通话结束

$.ajax({url: '/'}).done(function(data) {});

对于您的代码，它将类似于：

$('#fileupload').fileupload({
    url: url,
    dataType: 'json',
    success: function (data) {
        alert("Success!");
    },
    progressall: function (e, data) {
        var progress = parseInt(data.loaded / data.total * 100, 10);
        $('#progress .progress-bar').css(
            'width',
            progress + '%'
        );
    }
})
.done(function (e, data) {
        $.each(data.result.files, function (index, file) {
            $('<p/>').text(file.name).appendTo('#files');
        });
    )
.prop('disabled', !$.support.fileInput)
    .parent().addClass($.support.fileInput ? undefined : 'disabled');
});
