如何设置一个值到HTML文件输入？ [英] How to set a value to a file input in HTML?

问题描述

 < input type =file/> 
  

如何设置这个值？

试想：






$ b pre> < form name =foomethod =postenctype =multipart / form-data>
< input type =filevalue =c：/passwords.txt>
< / form>
< script> document.foo.submit（）;< / script>


您不希望您访问的网站能够这样做吗？ =）

<input type="file" />

How can I set the value of this?

解决方案

You cannot due to security reasons.

Imagine:

<form name="foo" method="post" enctype="multipart/form-data">
    <input type="file" value="c:/passwords.txt">
</form>
<script>document.foo.submit();</script>

You don't want the websites you visit to be able to do this, do you? =)
