jQuery文件上传插件没有调用成功回调

Question

我正在使用jQuery fileupload插件,我想在完成fileupload后做一些自定义jQuery的东西

从这里 https://github.com/blueimp/jQuery-File-Upload/wiki/Options

现在它说了这个

Callback for successful upload requests.
$('#fileupload')
       .bind('fileuploaddone', function (e, data) {/* ... */})

现在我已经在我自己的js文件中定义了这个自定义函数进行测试

$('#fileupload').bind('fileuploaddone', function (e, data) {/* ... */
alert('Hello');
})

但它不起作用.

但如果我在这里编辑主文件

  // Callback for successful uploads:
            done: function (e, data) {

然后它工作.

Answer 1

检查服务器端上载脚本是否返回JSON回复 - 在我的情况下,当回复为空,但文件上传成功时它不起作用.

所以,下面是jQuery 1.9.1和最新版本的"jQuery文件上传插件" - 5.21.3

$("#fileupload").bind("fileuploaddone", function (e, data) {
    console.log("fileuploaddone event fired");
});

查看库代码，似乎所有事件都被重命名，从而删除了“ fileupload”……因此，“ fileuploaddone”变成了“ done”。对所有其他回调有效。看这部分：

    // Other callbacks:
    // Callback for the submit event of each file upload:
    // submit: function (e, data) {}, // .bind('fileuploadsubmit', func);
    // Callback for the start of each file upload request:
    // send: function (e, data) {}, // .bind('fileuploadsend', func);
    // Callback for successful uploads:
    // done: function (e, data) {}, // .bind('fileuploaddone', func);
    // Callback for failed (abort or error) uploads:
    // fail: function (e, data) {}, // .bind('fileuploadfail', func);
    // Callback for completed (success, abort or error) requests:
    // always: function (e, data) {}, // .bind('fileuploadalways', func);
    // Callback for upload progress events:
    // progress: function (e, data) {}, // .bind('fileuploadprogress', func);
    // Callback for global upload progress events:
    // progressall: function (e, data) {}, // .bind('fileuploadprogressall', func);
    // Callback for uploads start, equivalent to the global ajaxStart event:
    // start: function (e) {}, // .bind('fileuploadstart', func);
    // Callback for uploads stop, equivalent to the global ajaxStop event:
    // stop: function (e) {}, // .bind('fileuploadstop', func);
    // Callback for change events of the fileInput(s):
    // change: function (e, data) {}, // .bind('fileuploadchange', func);
    // Callback for paste events to the pasteZone(s):
    // paste: function (e, data) {}, // .bind('fileuploadpaste', func);
    // Callback for drop events of the dropZone(s):
    // drop: function (e, data) {}, // .bind('fileuploaddrop', func);
    // Callback for dragover events of the dropZone(s):
    // dragover: function (e) {}, // .bind('fileuploaddragover', func);

如果您对正在发生的事情有疑问，请查看其中的代码。该库未压缩，因此很容易看到。例如

// start: function (e) {}, // .bind('fileuploadstart', func);

start回调已实现。fileuploadstart不是。
