jquery.form.js提交 input file中的文件

现今的主流浏览器由于ajax提交form表单无法把文件类型数据提交到后台，供后台处理，可是开发中由于某些原因又不得不用ajax提交文件，解决方案：

下面说说 jquery.form.min.js 插件，它是一款优秀的Ajax表单插件，我们可以非常容易的使用它处理表单控件的值，清空和复位表单控件，附件上传，以及完成Ajax表单提交。jquery.form.min.js 有两个核心方法ajaxForm()和ajaxSubmit()，下面以实例来简单说明其提交file文件方式：

<!-- Modal：更新授权 -->
	<div class="modal fade" id="update-authorization-modal" tabindex="-1" role="dialog"
		aria-labelledby="exampleModalLabel" aria-hidden="true">
		<div class="modal-dialog" role="document">
			<div class="modal-content">
				<div class="modal-header">
					<button type="button" class="close" data-dismiss="modal" aria-hidden="true">
						×
					</button>
					<h4 class="modal-title"> 更新授权 </h4>
				</div>
				<form id="update-authorization-modal-form" class="form-horizontal" action="">
					<div class="modal-body">
						<div class="form-group row">
							<label
								class="col-sm-3 col-md-3 col-lg-3 col-xl-3 control-label font-normal align-right">授权文件：</label>
							<div class="col-sm-7 col-md-7 col-lg-7 col-xl-7">
								<div class="file-input-container">
									<input type="file" class="form-control file-input"
										id="update-authorization-modal-file" name="updateAuthorizationModalFile" />
								</div>
							</div>
						</div>
					</div>
					<div class="modal-footer">
						<button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
						<button type="submit" class="btn btn-success">发送</button>
					</div>
				</form>
			</div>
		</div>
	</div>
