我有两个JSON文件：
第一个JSON：
$scope.deviceList =
{
"devices": [
{
"sub_family": "6s Plus",
"presales_description": "iPhone 6 Plus features a stunning 5.5-inch Retina HD display, amazing cameras and many advanced features, all in a breakthrough design. A 5.5-inch Retina HD display. An A8 chip with 64-bit desktop-class architecture. 8MP iSight camera with Focus Pixels and optical image stabilisation. Touch ID. Fast 4G LTE and Wi-Fi.1 Long battery life.2 And iOS 9 and iCloud.",
"Camera": true,
"device_type": "smartphone",
"presales_vendor": "Apple",
"sim_form-factor": "Nano",
"memory": 64,
"device_class": "HC14",
"TV Capable": true,
"family": "iPhone",
"specification_reference": "D20",
"variants": [
{
"colour": "Space Grey",
"default": true,
"presales_sequence": 961,
"s_code": "S0346715",
"credit_risk": 750,
"colour_code": "#898989",
"max_credit_term": 24,
"list_price": 759,
"presales_start_date": "02/04/2016"
},
{
"colour": "Silver",
"default": true,
"presales_sequence": 961,
"s_code": "S0346717",
"credit_risk": 750,
"colour_code": "#e5e5e5",
"max_credit_term": 24,
"list_price": 759,
"presales_start_date": "02/04/2016"
}
]
}
]
}
第二个JSON：
{
"stocks":[
{
"estAvailableDate":"",
"quantityAvailable":"0",
"obsolete":"false",
"handsetScode":"S0346717",
"backOrderable":"Y",
"stockState":"OutOfStock",
"stock_update":"13/10/2016 10:57",
"preorder":true,
"stock_next_amount":"0"
},
{
"estAvailableDate":"",
"quantityAvailable":"0",
"obsolete":"false",
"handsetScode":"S0346715",
"backOrderable":"Y",
"stockState":"OutOfStock",
"stock_update":"13/10/2016 10:57",
"preorder":true,
"stock_next_amount":"0"
}
]
}
我需要获取＆＃34; s_code＆＃34;来自第一个JSON文件的属性值，需要与第二个JSON＆＃34; phonesScode＆＃34;进行比较。适当的价值。如果存在匹配的大小写，则需要显示第二个JSON中的stockState属性值。
任何帮助将不胜感激。
代码：
$scope.showDataMemory = function(item){
$('.'+item).addClass('active').removeClass('hide');
$('.'+item).siblings('div.device_overview').removeClass('active').addClass('hide');
**var result111 = $scope.deviceList.devices.map(function(device) {
return device.variants.map(function(variant) {
return stocks.filter(function(stock){
return stock.handsetScode === variant.s_code;
})[0].stockState;
});
});
alert(result111);**
}

你可以这样做。
你的JSON似乎也不完整，所以我假设他们的结构是这样的。
var devices = [

// Main function
var result = devices.map(function(device) {
return device.variants.map(function(variant) {
return stocks.filter(function(stock){
return stock.handsetScode === variant.s_code;
}).map(function(stock) {
return stock.stockState;
});
});
});
console.log(result);

试试这个工作示例。它将按照您的要求工作。
