关于input上传文件
上传文件使用 <input type="file" value="上传文件" />
同时，需要多选时需添加属性：<input type="file" value="上传文件" multiple="multiple" />
注意：input[type=file]无法设置好看的样式，所以我更多采取[type=button]放在下面[type=file]放在上面不透明度为0的方式

<input class="btnFile" type="file" name="" id="" value="" accept=".pdf,.png,.jpg,.gif,.jpeg" multiple="multiple" />
