我正在尝试使用来自数据库的更详细的JSON文件填充bootstrap-carousel。我正在添加JSON详细信息以便详细了解。早期的My JSON文件是：
old.json
[
{"screen": [{
"img" : "../static/images/product/34.jpg",
"price": "Rs 100",
"href": "#mobile/1234"
},{
"img": "../static/images/product/34.jpg",
"price": "Rs 101",
"href":"#mobile/1234"
},{
"img":"../static/images/product/34.jpg",
"price": "Rs 102",
"href":"#mobile/1234"
},{
"img":"../static/images/product/34.jpg",
"price": "Rs 103",
"href":"#mobile/1234"
}
]},
{"screen": [{
"img" : "../static/images/product/34.jpg",
"price": "Rs 100",
"href": "#mobile/1234"
},{
"img": "../static/images/product/34.jpg",
"price": "Rs 101",
"href":"#mobile/1234"
},{
"img":"../static/images/product/34.jpg",
"price": "Rs 102",
"href":"#mobile/1234"
},{
"img":"../static/images/product/34.jpg",
"price": "Rs 103",
"href":"#mobile/1234"
}
]}
]
现在，我正在尝试用更详细的JSON文件填充它。

正如您所看到的，我需要将我的new.JSON分组为屏幕属性下的一组4。为此我写了一个for循环：
mainApp.controller('MultiCarouselController', function($scope, $http) {
$scope.products = [];
$scope.Math = Math;
$http.get("/get_broad_category_products/?BroadCategory=BroadCategory3")
.success(function (response) {
$scope.products = response;
var iteratation = Math.ceil($scope.products.length/4);
var carouselJson = [];
for(var index = 0; index < iteratation; index++){ // kinda 2D matrix as [0,1],[0,2],[1,1],[1,2]
var temp = [];
for (var i = (index*4) ; i < (4*(index+1)) ; i++){
temp = temp.concat($scope.products[i]) // concatenating 4 JSON as a group
}
carouselJson.push(temp); // pushing group to new JSON
}
console.log(carouselJson);
}).error(function(){
console.log('Error happened ... ');
});
});
此angularJS controller工作正常，如何添加＆＃34; screen＆＃34; 属性，然后向其添加4个JSON组
我虽然做了类似的事情：
for(var index = 0; index < iteratation; index++){ // kinda 2D matrix as [0,1],[0,2],[1,1],[1,2]
var temp = [];
for (var i = (index*4) ; i < (4*(index+1)) ; i++){
temp = temp.concat($scope.products[i]) // concatenating 4 JSON as a group
}
var jsTemp = [] ;
carouselJson.push(jsTemp.screen.push(temp)); // Errrrr.... screen property is not there in jsTemp. Now ????
}
小帮助可能会起到作用!!!

我根本不是角色的粉丝所以不知道它如何处理JSON。
然而，JSON只是一个序列化的对象，因此只要您采取一些预防措施，它就很容易混合和匹配。
考虑以下两个json文件。 JSON1是产品列表，每个产品都有一个该产品唯一的ID。第二个JSON JSON2修改了第一个JSON，它具有特定名称“extraImages”，“newItems”，“updates”，“newData”，我们必须添加到第一个。
连接它们不会，因为它们不是数组。你也不能只是连接JSON字符串，它不起作用。
您可以编写一个通用的对象连接函数，但这将加入两个没有任何上下文知识。它如何知道放置额外图像的位置？如何知道每个产品都可以通过ID识别？
要加入这两个对象，我们需要了解两个文件中每个项目的数据结构和语义含义。
无论如何将两个JSON文件作为字符串。
var JSON1 = `{
"item1":{
"id":100,
"desc":"a product",
"images":[
"img1.jpg",
"img2.jpg",
]
},
"item2":{
"id":101,
"desc":"another product",
"images":"img11.jpg", // this item has only one image so it just has a string
},
"item5":{
"id":105,
"desc":"a product without images",
},
}`;
var JSON2 = `{
"extraImages":[{
"id":101,
"images":[
"imageA.png",
"imageC.png"
]
}],
"newData":[{
"id":100,
"price":100,
}
],
"update":[{
"id":100,
"desc":"Best buy product",
}
],
"newItems":[{
"item3":{
"id":102,
"desc":"Just on the docks",
"images":[
"Blury11.jpg",
]
},
}
}`
因为字符串JSON是没用的。难以搜索和查找数据。所以JavaScript有一个内置对象来处理JSON，称为有趣JSON
JSON对象有两种方法JSON.stringify(Obj)和JSON.parse(String)
JSON.stringify采用基本的JS数据类型并将其转换为
JSON字符串。JSON.parse从任何来源获取json字符串并进行转换
它回到JS Object，Array ...... 首先，将JSON字符串转换为对象。
var items = JSON.parse(JSON1);
var extras = JSON.parse(JSON2);
现在我们有两个可以操作和加入的普通JS对象。
让我们做图像。额外的图像是一个数组，每个项目都有一个ID和一组图像名称。
// we know the name of the object that has extra images so check if its there
// and then itterate all the items in the array
if(extras.extraImages !== undefined){ // Does this property exist
extras.extraImages.forEach(function(item){ // itterat over each item
var arrayOfImages;
// do the images exist and if so are they as an array
if(item.images !== undefined && typeof item.images === "array"){
arrayOfImages = item.images;
}
// the data structure may vary depending on what is serving the JSON
// data so you can add code to take differing types
// Now to find the matching item in the items object
// check that there is an array of images to add and tha
// the item we have has an item id we can use to find the existing item
if(arrayOfImages !== undefined && item.id !== undefined){
// continue on further down
因此我们找到了一个额外的图像项目，其中包含ID和图像名称数组。我们需要找到具有该ID的产品。正如我们将要做的那样，我们可以多次写一个函数来做到这一点。
// pass the items object that may contain the item with the ID we are looking for
function getItemById(items,id){
for(var itemName in items){ // iterate each named item. itemName is
// just a variable it could be any var name.
// It contains a string holding each enumerable
// properties name in turn
现在检查指定的属性是否有id，你可能想要检查id是否具有我们正在寻找的id。
if(item[itemName].id === id){
如果项目没有id，则会抛出错误，并且有许多原因可能会出现无法正确构造的可枚举属性。因此检查id是否存在然后检查其值。与C / C ++ / C＃不同，比较的顺序始终是从左到右。在第一个错误时，if(将退出（）而不进行任何进一步的比较。
因此，只要您首先测试它不会抛出ReferenceError: id is not defined
if(items[itemName].id !== undefined && items[itemName].id == id){
永远不会抛出错误
if(items[itemName].id == id && items[itemName].id !== undefined ){
如果id不存在，则可以。
无论如何我分歧。
if(items[itemName].id == id && items[itemName].id !== undefined ){
// found the item with matching id
return items[itemName]; // so return it
}
}
return undefined; // nothing found that matches so return undefined
} //end of function
回到添加额外的图像。我们刚刚测试过，发现了一个带有id和一些额外图像名称的extraimage项目。
// use the function to get the item
var existingItem = getItemById(items,item.id);
// check that we found one
if(existingItem !== undefined){
// check to see if it has a images
if(existingItem.images === undefined){
// no image so creat images and add an empty array
existingItem.images = []
}else // if it does is it an array
if(typeof existingItem.images !== "array"){
// not an array we will assume what is there
// is an image description of some type
// so convert the existing images object into
// an array and add the existing item into it
existingItem.images = [existingItem.images];
}
// now we are sure the images array is correct so lets
// add the new images to i
existingItem.images existingItem.images.concat( arrayOfImages);
}
}
}); // end of forEach lop
} // endo of adding new images
所以把它包起来
// code to join extraImages to items
if(extras.extraImages !== undefined){
extras.extraImages.forEach(function(item){
var arrayOfImages;
if(item.images !== undefined && typeof item.images === "array"){
arrayOfImages = item.images;
}
if(arrayOfImages !== undefined && item.id !== undefined){
var existingItem = getItemById(items,item.id);
if(existingItem !== undefined){
if(existingItem.images === undefined){
existingItem.images = []
}else
if(typeof existingItem.images !== "array"){
existingItem.images = [existingItem.images];
}
existingItem.images existingItem.images.concat( arrayOfImages);
}
}
});
}
// was going to show all the other joins for extras.update, newItems, and newData
// too much for one answer.
我认为这是一个很长的答案。我假设你看到正在做什么以及如何使用它来将两个对象连接在一起，同时符合它的语义。您应该能够编写一个函数来为您的数据执行相同的操作。通过JSON.parse将两个JSON字符串转换为对象，迭代对象结构，遵循数据的语义，根据需要创建或附加数据。
最后，我假设您需要将连接数据作为JSON字符串，将更新后的对象转换回json字符串。
JSON1 = JSON.stringify(items); // convert the updated items object to a JSON string
现在你可以将它传回Angular的JSON抽象层来完成你需要的工作。
希望这会有所帮助。也许在Angular中有一种方法，但由于没有人回答所需的东西，我不想玷污我的纯粹方式（令人讨厌的Angular），这将给你一些额外的JS基础并允许你解决你的问题。

如果我正确读取此内容，您需要将新属性添加到temp数组中的每个元素。为此，您可以尝试从$scope.products[i]创建新对象。
for(var index = 0; index < iteratation; index++){ // kinda 2D matrix as [0,1],[0,2],[1,1],[1,2]
var temp = [];
for (var i = (index*4) ; i < (4*(index+1)) ; i++){
var destObj = $scope.products[i];
destObj.screen = 'xx' // Assign your value here.
temp = temp.concat(destObj) // concatenating 4 JSON as a group
}
carouselJson.push(temp);
}
希望这会有所帮助......

这个链接帮助了我
JavaScript Array Push key value
改变了我的循环：
var carouselJson = [];
for(var index = 0; index < iteratation; index++){ // kinda 2D matrix as [0,1],[0,2],[1,1],[1,2]
var temp = [];
var screen = ['screen'];
var obj = {};
for (var i = (index*4) ; i < (4*(index+1)) ; i++){
temp = temp.concat($scope.products[i]); // concatenating 4 JSON as a group
}
obj[screen]=temp;
carouselJson.push(obj); // pushing group to new JSON
}
$scope.mCarousels = carouselJson;
