json从另一个域使用jquery

对不起，如果这是一个重复，但我无法找到任何相关线程的答案。我试图从API获取JSON并阅读内容，但无法解析。代码如下。我使用jsonp，因为json不能跨域使用。json从另一个域使用jquery

function getBbyJson() 
{ 
    link = "http://api.remix.bestbuy.com/v1/products(name=playbook*)?show=sku,name,regularPrice,shortDescription&format=json&apiKey="+apikey 
    $(document).ready(function(){ 
     $.ajax({ 
      type: "GET", 
      url: link, 
      dataType: "jsonp", 
      success: function(data){ 
       for (var i = 0,len = data.products.length; i < len; i++) { 
        var name = data.products[i].name; 
        $('<div class="name" id="item_'+i+'"></div>').html(name).appendTo('#container');       
       } 
      } 
     }); 
    }); 
}

使用此功能，BBY返回一个错误400使用以下信息

"Couldn't understand '/v1/products(name=playbook*)?show=sku,name,regularPrice,shortDescription&format=json&apiKey=apikey&callback=jQuery17206852765618823469_1341853386681&_=1341853391235'"

jquery的方法是增加一个回调函数，并在最后的随机数。

我可以删除回调函数的下面添加

jsonp: false 
jsonpCallback: ""

的代码，但，我不能摆脱的jQuery产生的随机数。我不知道如何从这里开始。我在本地的json文件上使用了相同的功能，并且工作顺利。

从BBY返回JSON，如果我粘贴到浏览器链接低于

-1'“jQuery的方法是添加一个回调功能，并在最后一个随机数。“这就是它应该做的。请在提问之前多研究一下。例如，请参阅[jQuery.ajax（）]（http://api.jquery.com/jQuery.ajax/）文档。 – merv 2012-07-09 18:08:11

也许这可以帮助你： http://wiki.asp.net/page.aspx/1734/jquery-cross-domain-ajax-call-using-jsonp/

function getBbyJson() 
{ 
    var link = "http://api.remix.bestbuy.com/v1/products(name=playbook*)"; 
    $(document).ready(function(){ 
     $.ajax({ 
      type: "GET", 
      url: link, 
      crossDomain: true, 
      contentType: "application/json; charset=utf-8", 
      data: { show: "sku,name,regularPrice,shortDescription", 
        apiKey:apikey}, 
      dataType: "jsonp", 
      success: function(data){ 
       for (var i = 0,len = data.products.length; i < len; i++) { 
        var name = data.products[i].name; 
        $('<div class="name" id="item_'+i+'"></div>').html(name).appendTo('#container');       
       } 
      } 
     }); 
    }); 
}

谢谢，这绝对有帮助！我还必须添加“缓存：真”，并照顾它！ – fsiddiq 2012-07-09 17:49:37

@fsiddiq不客气 – 2012-07-09 17:59:18

尝试添加到您的代码：

$.ajax({ 
      type: "GET", 
      url: link, 
      dataType: "jsonp", 
      success: function(data){ 
       for (var i = 0,len = data.products.length; i < len; i++) { 
        var name = data.products[i].name; 
        $('<div class="name" id="item_'+i+'"></div>').html(name).appendTo('#container');       
       } 
      } 
      error : function(data){ 
         console.log(data); 
        } 
     });

，看看输出
