json從另一個域使用jquery

對不起，如果這是一個重複，但我無法找到任何相關線程的答案。我試圖從API獲取JSON並閱讀內容，但無法解析。代碼如下。我使用jsonp，因爲json不能跨域使用。json從另一個域使用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返回一個錯誤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的方法是增加一個回調函數，並在最後的隨機數。

我可以刪除回調函數的下面添加

jsonp: false 
jsonpCallback: ""

的代碼，但，我不能擺脫的jQuery產生的隨機數。我不知道如何從這裏開始。我在本地的json文件上使用了相同的功能，並且工作順利。

從BBY返回JSON，如果我粘貼到瀏覽器鏈接低於

-1'「jQuery的方法是添加一個回調功能，並在最後一個隨機數。「這就是它應該做的。請在提問之前多研究一下。例如，請參閱[jQuery.ajax（）]（http://api.jquery.com/jQuery.ajax/）文檔。 – merv 2012-07-09 18:08:11

也許這可以幫助你： 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({

      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++) {

謝謝，這絕對有幫助！我還必須添加「緩存：真」，並照顧它！ – fsiddiq 2012-07-09 17:49:37

嘗試添加到您的代碼：

$.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); 
        } 
     });

，看看輸出
