Question

我的问题是这段代码：xmlhttp.open("GET","oy.php?antivirus="+y,true);

无论我做什么，

y都是0。我选择了一个单选按钮。然后单击“投票”按钮。但没有变化。 y始终为0.

ajax和html代码：

<script>
     function send_vote()
            {
                  if (window.XMLHttpRequest)
                  {// code for IE7+, Firefox, Chrome, Opera, Safari
                    xmlhttp=new XMLHttpRequest();
                  }
                    else
                  {// code for IE6, IE5
                    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
                  }
                  var x;
                  var i;
                  var y  = 0;
                  for(i = 1 ; i < 8 ; i++){
                    x = document.getElementById(i).checked;

                    if(x == true){
                         y = document.getElementById(i).value;
                        break;
                    }
                  }



                  xmlhttp.onreadystatechange=function()
                  {
                  if (xmlhttp.readyState==4 && xmlhttp.status==200)
                    {
                    var a = xmlhttp.responseText;

                            alert(a);
                    }
                  }


                xmlhttp.open("GET","oy.php?antivirus="+y,true);
                xmlhttp.send();


            }

htaccess文件：

Options +FollowSymlinks
DirectorySlash Off
RewriteEngine On



RewriteRule ^([a-z0-9\-\_]+)$ index.php [L,NC]

RewriteRule ^([a-z0-9\-\_]+)/([a-z0-9\-\_]+)$ index.php [L,NC]

RewriteRule ^([a-z0-9\-\_]+)/([a-z0-9\-\_]+)/([a-z0-9\-\_]+)$ index.php [L,NC]

Answer 1

添加一些条件，这样就不会重写现有文件或目录：

Options +FollowSymlinks
DirectorySlash Off
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([a-z0-9\-\_]+)$ index.php [L,NC]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([a-z0-9\-\_]+)/([a-z0-9\-\_]+)$ index.php [L,NC]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([a-z0-9\-\_]+)/([a-z0-9\-\_]+)/([a-z0-9\-\_]+)$ index.php [L,NC]
