Question

我目前正在开发一个小项目来掌握使用API并从中解析数据。我目前遇到了一个问题，我无法从我得到的JSONP结果中提取特定元素。我只需要地址就可以将字符串传递给Google Map API，然后将标记放在我已经生成的地图上。

以下是我的脚本示例。我是JQuery的新手，所以任何帮助都会非常感激。请注意第一个函数getBByJSOn()已经产生了一个正确的结果，我将其解析到页面。它的功能在我遇到问题。

function getBbyJson()
    {   
        $.ajax({
            type: "GET",
            url: main_link,
            dataType: "jsonp", 
            cache: true,
            crossdomain: true,
            success: function(data){                                        

                    for (var i = 0,len = data.products.length; i<len; i++) {    
                        var name = data.products[i].name;
                        var price = data.products[i].regularPrice;
                        var sku = data.products[i].sku;
                        var desc = data.products[i].shortDescription;
                        $('<div class="name" id="item_'+i+'"></div>').html("Name:"+name).appendTo('#result-container');
                        $('<div class="sku"></div>').html("SKU:  "+sku).appendTo('#item_'+i, '#result-container');
                        $('<div class="price"></div>').html("Price:  "+price).appendTo('#item_'+i);
                        $('<div class="description"></div>').html("Desc:  "+desc).appendTo('#item_'+i);
                    }
                } 
            });
        getBbyJsonBB();
    }

    function getBbyJsonBB()
    {   
            $.ajax({
                type: "GET",
                url: link3,
                dataType: "jsonp", 
                cache: true,
                crossdomain: true,
                success: function(data){
                        for (var i = 0,len = data.products.length; i<len; i++) {    
                            var name2 = data.products[i].address;                       
                        //address[i] = data.product.stores[i].address;
                        //storeId [i]= data.stores[i].storeId;
                        $('<div class="name" id="item_'+i+'"></div>').html("Name:"+name2).appendTo('#result-container');
                        //$('<div class="sku"></div>').html("ADD: "+address[i]).appendTo('#item_'+i, '#result-container');
                        //$('<div class="price"></div>').html("Price:  "+price).appendTo('#item_'+i);
                        //$('<div class="description"></div>').html("Desc:  "+desc).appendTo('#item_'+i);
                    }
                } 
            });

    }

这是我需要操作的JSON结果的示例。

  "currentPage": 1,
  "totalPages": 2,
  "warnings": "Your product criteria matches too many records.  That exceeds number of records that we allow on the product side of a product-store query.

您需要stores的内循环。你说的是：对于每个product（外循环），请告诉我每个store（内循环）。

演示： http://jsfiddle.net/ThinkingStiff/uNW78/

脚本：

for ( var productIndex = 0, product; productIndex < data.products.length; productIndex++ ) {   
    product = data.products[productIndex];    
    for( var storeIndex = 0, store; storeIndex < product.stores.length; storeIndex++ ) {
        store = product.stores[storeIndex];
        $( '#result-container' ).append( '<div class="name" id="item_' + productIndex + '"></div>' )
            .append( 'name: ' + store.name + '<br />' )
            .append( 'storeId: ' + store.storeId + '<br />' )
            .append( 'address: ' + store.address + '<br />' );           
    };   
};

使用Jquery将JSON API Request的元素传递给数组
