您可以使用Javascript onclick事件。浏览器仍然会显示 index.php ，但onclick事件将首先触发，并将浏览器重定向到正确的页面。

 < a href =index.phponclick =location.redirect（'index.php＃dev'）;> 
 

How can I hide the hash value from the following link href in the address bar?

<a href="index.php#dev_name">

So it'll redirect me to a the index.php#dev_name, but I want the address bar to only show index.php

You can use a Javascript onclick event. The browser will still show index.php, but the onclick event will trigger first, and redirect the browser to the right page.

<a href="index.php" onclick="location.redirect('index.php#dev');">
