jQuery的弃用功能跨域响应

Question

基本上我一直用这个功能来实现跨域JSONP但功能_success.call(this, { responseText: data.results[0].replace(/<script[^>]+?\/>|<script(.|\s)*?\/script>/gi, '')}, 'success');失败响应的一部分Uncaught TypeError: Object #<Object> has no method 'isResolved'

现在我知道.isResolved()http://api.jquery.com/deferred.isResolved/已经过时，所以我在想，我怎么能去处理它已经接管的deffered.state()http://api.jquery.com/deferred.state/。

任何帮助将大规模赞赏。回到以前的jQuery版本并不是真正的选择。

以下全部功能。

jQuery.ajax = (function(_ajax){ 

    var protocol = location.protocol, 
     hostname = location.hostname, 
     exRegex = RegExp(protocol + '//' + hostname), 
     YQL = 'http' + (/^https/.test(protocol)?'s':'') + '://query.yahooapis.com/v1/public/yql?callback=?', 
     query = 'select * from html where url="{URL}" and xpath="*"'; 

    function isExternal(url) { 
     return !exRegex.test(url) && /:\/\//.test(url); 
    } 

    return function(o) { 

     var url = o.url; 

     if (/get/i.test(o.type) && !/json/i.test(o.dataType) && isExternal(url)) { 

      // Manipulate options so that JSONP-x request is made to YQL 

      o.url = YQL; 
      o.dataType = 'json'; 

      o.data = { 
       q: query.replace(
        '{URL}', 
        url + (o.data ? 
         (/\?/.test(url) ? '&' : '?') + jQuery.param(o.data) 
        : '') 
       ), 
       format: 'xml' 
      }; 

      // Since it's a JSONP request 
      // complete === success 
      if (!o.success && o.complete) { 
       o.success = o.complete; 
       delete o.complete; 
      } 

      o.success = (function(_success){ 
       return function(data) { 
        if (_success) { 
         // Fake XHR callback. 
         _success.call(this, { 
          responseText: data.results[0] 
           // YQL screws with <script>s 
           // Get rid of them 
           .replace(/<script[^>]+?\/>|<script(.|\s)*?\/script>/gi, '') 
         }, 'success'); 
        } 

       }; 
      })(o.success); 

     } 

     return _ajax.apply(this, arguments); 

    }; 

})(jQuery.ajax);

我和你有同样的问题，并找到了解决办法。尽管事情发生在前一段时间，因为问题被问到，如果有人像我一样遇到这个问题，我决定发布我的解决方案。

在jquery.xdomainajax.js去排队62，改变

if (_success) { 
    // Fake XHR callback. 
    _success.call(this, { 
     responseText: (data.results[0] || '') 
      // YQL screws with <script>s 
      // Get rid of them 
      .replace(/<script[^>]+?\/>|<script(.|\s)*?\/script>/gi, '') 
    }, 'success'); 
} 

到

if (_success) { 
    // Fake XHR callback. 
    var obj = { 
     responseText: (data.results[0] || '') 
      // YQL screws with <script>s 
      // Get rid of them 
      .replace(/<script[^>]+?\/>|<script(.|\s)*?\/script>/gi, '') 
    }; 
    $.extend(obj,{ 
     isResolved: function() { return true; }, 
     done: function() { return true; } 
    }); 

    _success.call(this, obj, 'success'); 
}
