Ajax为什么找不到网址？

我有一个Ajax调用，但它没有从php文件获得响应，而是显示404。地址栏中的url是“mydomain.com/checkCity/”，使用Ajax的文件位置是“/php/adt/script.php”，要调用的php文件位置是“/php/adt/witable.php”，我通过使用htaccess使用虚拟URL。这里是我的Ajax调用：

    $.ajax({
        type: "POST",
        url: "/available.php",
        data: "city="+city,
        success: function(response){
        alert(response);
}
});

这是我的htaccess文件：

    <IfModule mod_rewrite.c>
RewriteEngine On

RewriteBase /

RewriteRule ^index\.php$ - [L]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . /index.php [L]

</IfModule>

我注意到的一件事是，当我在地址栏中搜索url时，它将加载php文件，而不是使用Ajax调用。我目前正在Apache2.2本地主机上运行这个程序，谢谢您的建议。

I'm assuming that you're seeing the 404 error message in the error log/console for your browser? It should also be displaying the URL that is returning the 404 response which, given your request, would be: http://www.mysite.com/available.php.

Problem

The problem is that your ajax call contains a / at the start of the URL parameter. This signifies the root domain of the website (i.e. it points to http://www.mysite.com/available.php).

url: "/available.php",

Solution

Simply change the url parameter to one of the following correct URLs

url: "http://www.mysite.com/php/advert/available.php",

OR

url: "/php/advert/available.php",

OR

url: "available.php",

OR

url: "./available.php",

Code for clarification

$.ajax({
    type: "POST",
    url: "/php/advert/available.php",
    data: "city="+city,
    success: function(response){
        alert(response);
    }
});

Ok so I know this is outdated but I thought I would answer why this was happening. I moved on to other things and this was the last thing to do so I was forced to figure it out which actually only took about half hour.

Ajax wasn't reaching the url in chrome but would in firefox. I then found out that "adblock" was blocking the url - This was because the url had "advert" in it and as soon as I relocated and renamed the file, presto it worked.

So just in case someone finds themselves in a similar situation.

Thanks
