Question

jquery-fileupload

Answer 1

这是前端部分代码，后台是没错的，但是回调函数进的是fail这个
 $('#fileupload').fileupload('option', {
                url: 'upload',
                // Enable image resizing, except for Android and Opera,
                // which actually support image resizing, but fail to
                // send Blob objects via XHR requests:
                dataType: 'jsonp',  
                method:'post',
                maxFileSize: 50000000,
                fail:function(){
                 console.log("============1");
                 console.log(e);
                 console.log(data);
                 console.log("============2");
                },
                done:function(){
                 console.log("============4");
                 console.log(e);
                 console.log(data);
                 console.log("============5");
                }
                //acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i
            });
