网页上添加一个input file HTML控件:

<input id="File1" type="file" />

默认是这样的,所有文件类型都会显示出来,如果想限制它只显示我们设定的文件类型呢,比如“word“,”excel“,”pdf“文件 

解决办法是可以给它添加一个accept属性,比如:
 

<input id="File1" type="file"  accept=".xls,.doc,.txt,.pdf"  />

这样选择的时候默认会显示为这样:

文件选择框内只显示出你自定义文件类型的文件,也还比较方便。

不过这只是最简单的掩人耳目的做法,还是能选择其它文件类型:

所以,如果要做到真正意义上限制类型做法(其实这种算不上限制,只是把你要的文件类型默认显示出来而已,并不是说不能选择其它的),还是要通过js或者后台来控制。

附支持的文件类型:
