几个星期前，我问放在这里如何检测当前页面并添加。主动类。我收到使用JavaScript以下工作的解决方案：在这里你可以查看问题：Stackoverflow问。

Few weeks ago I have asked on here how to detecting the current page and add class of .active. I have received the following working solution using JavaScript: You can view the question here: Stackoverflow Question.

$("#mainMenu a").filter(function () {
  var _href = location.href.replace(/#.*/, "");
  if (location.pathname === "/") {
     // change http://example.com/ to http://example.com/index.php
     _href += "index.php";
  }
  return _href === this.href;
}).addClass("active");

然而，我现在想从URL中的删除的扩展名为.php，我这样做，用下面的.httacess：

However, I now wanted to remove the .php extensions from the URL's and I did that using the following .httacess:

DirectoryIndex index.html index.php 
ErrorDocument 404 /404 
ErrorDocument 504 /504 

RewriteEngine On 
RewriteBase / 

# remove enter code here.php; use THE_REQUEST to prevent infinite loops 
# By puting the L-flag here, the request gets redirected immediately 
RewriteCond %{THE_REQUEST} ^GET (.*).php HTTP 
RewriteRule (.*).php$ $1 [R=301,L] 

# remove index 
# By puting the L-flag here, the request gets redirected immediately 
# The trailing slash is removed in a next request, so be efficient and 
# dont put it on there at all 
RewriteRule (.*)/index$ $1 [R=301,L] 

# remove slash if not directory 
# By puting the L-flag here, the request gets redirected immediately 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_URI} /$ 
RewriteRule (.*)/ $1 [R=301,L] 

# add .php to access file, but don't redirect 
# On some hosts RewriteCond %{REQUEST_FILENAME}.php -f will be true, even if 
# no such file exists. Be safe and add an extra condition 
# There is no point in escaping a dot in a string 
RewriteCond %{REQUEST_FILENAME}.php -f 
RewriteCond %{REQUEST_URI} !(/|.php)$ 
RewriteRule (.*) $1.php [L] 

现在的问题是，当我在上面添加的.httacess文件，JavaScript的停止工作......这是为什么？ 是否有这样做使用PHP的更有效的方法？

The problem is, when I added the .httacess file above, the JavaScript stopped working... Why is that? Is there a more efficient way of doing this using PHP?

推荐答案

它看起来像我有固定的，但我不知道，如果这个解决方案是好的，任何建议吗？ 我从index.php来/指数改变了href和它的工作原理...

It seem like I have fixed it, but I don't know if this solution is good, any advices please? I have changed the href from index.php to /index and it works...
