我在尝试例如jQuery的例子，让我吃惊，我有一个AJAX调用提的是超时错误状态没有定义。当我删除timeout属性，它工作得很好。 我下载的jQuery几天就回来，所以我pretty的确保它不是一个版本的问题。

我试图与Firefox（3.6.8），而不是其他任何浏览器。

为什么会出现这种情况？

修改：code段的意见提出的问题

  $。阿贾克斯（{
  键入：GET，
  数据类型：JSON，
  网址：PHPServiceProxy，
  超时：5000，
  成功：函数（回复）{} //注意：提供的原装code段在这里缺少一个逗号。
  错误：函数（XHR，textStatus，errorThrown）{}
}）;
 

解决方案

在暂停属性已经present jQuery的很长一段时间，所以我不认为你的问题是涉及到它。也许你有你的code语法错误。这应该工作：

  $。阿贾克斯（{
    键入：GET，
    数据类型：JSON，
    网址：PHPServiceProxy，
    超时：5000，
    成功：函数（回复）{

    }，
    错误：函数（XHR，textStatus，errorThrown）{

    }
}）;
 

I was trying out example jQuery examples and to my surprise, I got an error state for an AJAX call mentioning that timeout isn't defined. When I removed timeout attribute, it worked fine. I downloaded jQuery few days back, so I am pretty sure it's not a version problem.

I was trying with Firefox(3.6.8) and not any other browser.

Why would this occur?

Edit: Code snippet moved from the comments to the question

$.ajax({ 
  type: "GET", 
  dataType: 'json', 
  url: PHPServiceProxy, 
  timeout: 5000, 
  success: function(reply) { } // note: original code snippet provided was missing a comma here.
  error: function (xhr, textStatus, errorThrown) { } 
});

The timeout property has been present in jQuery for a long time so I don't think that your problem is related to it. Maybe you have a syntax error in your code. This should work:

$.ajax({ 
    type: 'GET', 
    dataType: 'json', 
    url: PHPServiceProxy, 
    timeout: 5000, 
    success: function(reply) { 

    },
    error: function (xhr, textStatus, errorThrown) { 

    } 
});
