我需要使用JavaScript创建这种格式的对象。
var results = {
"A-1": [
{ "object": "daily", "type": "when", "field": "Period" }
],
"A-2": [
{ "object": "weekly", "type": "when", "field": "Period" }
],
"A-3": [
{ "object": "monthly", "type": "when", "field": "Period" }
],
"B-1": [
{ "object": "Boston", "type": "who", "field": "City" },
{ "object": "AG", "type": "what", "field": "region" },
{ "object": "L1", "type": "where", "field": "Level" }
],
"B-2": [
{ "object": "New York", "type": "who", "field": "City" },
{ "object": "AG", "type": "what", "field": "region" },
{ "object": "L2", "type": "where", "field": "Level" }
],
"B-3": [
{ "object": "Paris", "type": "who", "field": "City" },
{ "object": "EURO", "type": "what", "field": "region" },
{ "object": "L1", "type": "where", "field": "Level" }
],
"B-4": [
{ "object": "Boston", "type": "who", "field": "City" },
{ "object": "AG", "type": "what", "field": "region" },
{ "object": "L2", "type": "where", "field": "Level" }
]
};
var periodList = "daily,weekly,monthly";
{J}格式的Web服务返回B-
部分键值,如下所示:
[
{ "object": "Boston", "level": "L1", "region": "AG" },
{ "object": "Paris", "level": "L1", "region": "EURO" },
{ "object": "Boston", "level": "L2", "region": "AG" },
{ "object": "China", "level": "L1", "region": "AP" },
{ "object": "New York", "level": "L2", "region": "AG" }
]
每个B-
对象都包含城市,区域和级别数组。
请帮助如何动态创建此结构?

只需使用两个简单的循环:
var results = {};
var periods = periodList.split(",");
for (var i=0; i<periods.length; i++)
results["A-"+(i+1)] = [
{"object": periods[i], "type": "when", "field": "Period"}
];
for (var i=0; i<json.length; i++)
results["B-"+(i+1)] = [
{"object": json[i].object, "type": "who", "field": "City"},
{"object": json[i].region, "type": "what", "field": "region"},
{"object": json[i].level, "type": "where", "field": "Level"}
];
没有任意嵌套,所以你不需要递归或任何沉重的东西。
