jQuery驗證1.7打破jQuery 1.5上的$ .getJSON（）？

美好的一天！

我正在jQuery 1.4.4上運行一個插件getJSON()，提升到1.5之後，回調不被調用。返回的JSON是有效的（我用驗證器檢查過）。

而且我注意到附加GET參數?callback=...這jQuery的添加到URL

看來我想通了如何創建一個測試案例，似乎jQuery驗證1.7（最新版本）是原因：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 

<html xmlns="http://www.w3.org/1999/xhtml" lang="ru"> 

<head> 
    <title> 

    </title> 

    <meta http-equiv="content-type" content="text/html; charset=utf8" />  
    <script type="text/javascript" src="js/jquery-1.5.min.js"></script> 
<!--  
    If I uncomment this - it will not work 
    <script type="text/javascript" src="js/jquery.validate.js"></script> 
--> 
</head> 
<body> 
<script type="text/javascript"> 
$(function(){ 
    $.ajaxSetup({ cache: false }); 
    $('#clickme').click(function(){ 
     var params = {userid : 'some-user-id-to-choose-right-temp-FTP-folder-for-the-user'}; 
     $.getJSON('/ajax-page_material-edit-ftp-filelist.php', params, function(data) { 
      console.log(data); 
     }); 
    }); 
}); 
</script> 

<a href="#" id="clickme">Click Me!</a> 

</body> 
</html>

也許這代碼插件是原因：

// ajax mode: abort 
// usage: $.ajax({ mode: "abort"[, port: "uniqueport"]}); 
// if mode:"abort" is used, the previous request on that port (port can be undefined) is aborted via XMLHttpRequest.abort() 
;(function($) { 
    var ajax = $.ajax; 
    var pendingRequests = {}; 
    $.ajax = function(settings) { 
     // create settings for compatibility with ajaxSetup 
     settings = $.extend(settings, $.extend({}, $.ajaxSettings, settings)); 
     var port = settings.port; 
     if (settings.mode == "abort") { 
      if (pendingRequests[port]) { 
       pendingRequests[port].abort(); 
      } 
      return (pendingRequests[port] = ajax.apply(this, arguments)); 
     } 
     return ajax.apply(this, arguments); 
    }; 
})(jQuery);

額外的URL參數`？callback = ...'用於[JSONP]（http://en.wikipedia.org/wiki/JSON#JSONP）。 – 2011-02-03 15:47:55
