HTML input file控件限制上传文件类型_动力节点Java学院整理-巨人网络通讯

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。
