Question

很抱歉，如果这是重复，但我找不到任何相关主题的答案。我试图从api获取一个json并阅读内容，但解析时遇到问题。代码如下。我正在使用jsonp，因为json不能跨域工作。

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400错误，并显示以下消息

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

jquery方法是添加一个回调函数，最后是一个随机数。

我可以通过添加以下代码来删除回调函数

jsonp: false
jsonpCallback: ""

但是，我无法摆脱jquery生成的随机数。我不知道如何从这里开始。我在本地json文件上使用了相同的函数，它没有任何障碍。

如果我在浏览器中粘贴链接，那么从bby返回json是

尝试添加代码：

$.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

也许这可以帮到你： 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');                        
                }
            } 
        });
    });
}
