I m 无法利用jquery s ajax功能成功填补。

运行页的URL为http:// localhost:9999/,目标(网络服务)的URL为http:// localhost:8080。港口没有相同,分别为999个和8080个。



下面是请求书和jquery ajax代码。

这是一个横跨阿加西电话的问题。基本上(至少是第2条),出于安全原因,将一项《组织条例》申请改为《组织条例》。昨天晚上,我看上去了同样的exact。

• 代表你称之为“jax”,例如PHP:

<?php /* get.php */
    $url = $_GET["Url"];
    echo file_get_contents($url);
?>

请您:

$.ajax({ url: "get.php?Url=realurl.com" });

那是一回事。

Answer 3


是什么手s? <代码>success或errorhandler? 您能否详细阐述“单项工作”的含义?

或许请<代码>alert在error上提供更多信息。手工艺:

error: function(XMLHttpRequest, textStatus, errorThrown) {
   //console.log is better at least for debugging. You can change this back to alert 
   //when your code goes into production
   console.log("Update unsuccessful. Status: ", textStatus, " error thrown: ", errorThrown);
}

。应当让你了解问题可能是什么。可能的数值是“时间外”、“频率”、“经修改的”和“质量”。一旦发现实际错误,请更新问题。

另外,如果你检查了Net tab,看看要求和答复。几个常见的错误来源:

Violating same-origin policy. You cannot make an AJAX to a different URL from the parent page.
Server-side errors. If your server returns something like a 500 response code, the request will fail.
Parsing errors. If you re expecting a specific response format like json or xml, and if the response is not in that format, the AJAX request will be unsuccessful.
