You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:
您不能这样做 - 出于安全考虑，浏览器将不允许这样做。尽管有变通方法，但事实是您不应指望这项工作。以下堆栈溢出问题与此处相关：
In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file"field, ostensibly for backward compatibility reasons.
除此之外，新的 HTML5 规范指出input type="file"，表面上是出于向后兼容性的原因，浏览器需要向该领域提供与 Windows 兼容的假路径。

So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.
因此，在较新的浏览器中，尝试获取路径更糟，而且毫无用处——您实际上会得到一个假的。
