HTML <input> accept 属性-规定能够通过文件上传进行提交的文件类型

定义和用法

文章地址: http://www.w3school.com.cn/tags/att_input_accept.asp

accept 属性规定了可通过文件上传提交的服务器接受的文件类型。

注意：accept 属性仅适用于 <input type="file">。

提示：请不要将该属性作为您的验证工具。应该在服务器上对文件上传进行验证。

实例

规定在文件上传中服务器只接受图像文件：

<form> <input type="file" name="pic" id="pic" accept="image/gif, image/jpeg" /> </form> 亲自试一下

属性值

值 描述 audio/* 接受所有的声音文件。 video/* 接受所有的视频文件。 image/* 接受所有的图像文件。 MIME_type 一个有效的 MIME 类型，不带参数。请参阅 IANA MIME 类型，获得标准 MIME 类型的完整列表。

在上传文件的时候，需要限制指定的文件类型，accept这个属性，只在FF和chrome中有效。那么accept能限制哪些文件呢？见下表。
