HTMLinput 标签的 accept 属性

实例

在文件上传中使用 accept 属性，本例中的输入字段可以接受 GIF 和 JPEG 两种图像：

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

亲自试一试

如果不限制图像的格式，可以写为：accept="image/*"。

定义和用法

accept 属性只能与 <input type="file"> 配合使用。它规定能够通过文件上传进行提交的文件类型。

提示：请避免使用该属性。应该在服务器端验证文件上传。

语法

<input accept="value">
