jQuery-File-Upload

 import excel

1.先用Ann 方法接

$('#uploadImages').on('change', function (){
            var formData = new FormData();
            for(var i = 0; i < this.files.length; i++){
                formData.append('file', this.files[i]);

                $.ajax({
                    url : '/file/upload',
                    type : 'post',
                    data : formData,
                    cache: false,
                    contentType: false,
                    processData: false,
                    success : function () {
                        alert("upload successfully")
                    }
                })

            }
        }
        $('form')[0].reset();
