HTMLinput标签的accept属性
执业资格证有哪些
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：
蓝天的诗
<form>
<input type="file" name="pic" id="pic"
accept="image/gif, image/jpeg"
/>
</form>
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
