好的,我一直在搜索这个网站,找到类似或有启发性的东西,但我完全卡住了。我得到一些有效的JSON,需要解析它来提取价格。我没有走得太远。
这是JSON:
{
"result": "success",
"prices": {
"vdc": {
"monthly": "1.00"
},
"network": {
"private": {
"monthly": "2.00"

"\/18 (6,666 IP Addresses)": {

},
"\/23 (900 IP Addresses)": {

}
},
"blocks": {

},

"ram": {

},
"volume": {

}
},
"snapshot": {

"monthly": "29.00"
}
}
}
}
在jsonlint [dot] com进行测试和验证。
经过多次尝试,测试,尝试,敲击我的键盘,尝试...这是我现在拥有的,但它没有产生预期的结果(我会告诉你那些是什么,就在代码片段之后)。
function gp(x){
for(var i in x){
console.log('700: ', x[i] );
if(x[i] != 'success'){
console.log(733);
console.log(x[i]);
for(var j in x[i]){
console.log(736);
console.log(x[i][j]);
}
}
}
}
在控制台中,我看到类似这样的内容:
我真正希望看到(或查找或解析)的内容是,例如,“volume”元素中“gb”的月价(或者是项目?)。
理想情况下,我想找到“音量”,“ram”和“cpu” - 验证它是音量,内存和CPU - 然后获得每月价格。我确实用JSON解析尝试了一些东西,但很明显,我还没有掌握它。
非常感谢任何帮助。

如果你想找到对象“volume”,“ram”和“cpu”这很简单:
var volume = x.prices.volume;
var ram = x.prices.server.ram;
var cpu = x.prices.server.cpu;
或者您可以直接使用它们:
console.log(x.prices.volume);
如果您想查找月度价格:
var prices = x.prices;
console.log('volume, monthly=', prices.volume.gb.monthly);
console.log('cpu, monthly=', prices.server.cpu.monthly);
console.log('ram, monthly=', prices.server.ram.monthly);
Javascript对象非常简单,只有2种语法可供访问:
// If the key you're accessing is a constant (hardcoded):
object.key = value;
// If the key you're accessing is stored in another variable:
var k = "key";
object[k] = value;
// Alternatively:
object["key"] = value;

我只是有点困惑,但这只是一个例子。将您的json保存到变量中,然后沿着具有节点名称的树向下(除非没有任何变量)。
这应该是每月的量
json.prices.volume.gb.monthly
