使用JavaScript浏览JSON [英] Navigating through JSON with JavaScript
问题描述
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。
OK, I have been searching through this site to find anything similar or enlightening, but I am completely stuck. I am getting some valid JSON and need to parse through it to extract prices. I'm not getting very far.
这是JSON：

"monthly": "1.00"
},

}
}
在jsonlint [dot] com上测试和验证。

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（我会告诉你是什么，就在代码片段之后。）
After much trying, testing, trying, banging head against my keyboard, trying...this is what I currently have, but it's not producing the desired results (I'll tell you what those are, right after the code snippet).
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]);
}
}
}
}
In控制台，我看到这样的事情：
In the console, I see something like this:
我真正想看的（或查找或解析）是，例如，音量中gb的月价格元素（或者它是一个项目？）。
What I really would like to see (or find or parse to) is, for example, the monthly price for "gb" from the "volume" element (or is it an item?).
理想情况下，我想找到音量，ram和cpu - 验证它是音量， ram和cpu - 然后得到每月价格。我确实尝试了一些使用JSON解析的东西，但显然，我还没有完全掌握它。
Ideally, I would like to find "volume", "ram" and "cpu" – verify that it's the volume, ram and cpu – then get the monthly price. I did try a few things with JSON parsing, but obviously, I haven't mastered that quite yet either.
任何帮助都将非常感谢。
Any help would be greatly appreciated.
推荐答案
如果你想找到对象volume，ram和cpu这很简单：
If you want to find the objects "volume", "ram" and "cpu" that's simple:
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：
or you can simply use them directly:
console.log(x.prices.volume);
如果您想查找每月价格：
If you want to find the monthly prices then:
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个访问它们的语法：
Javascript objects are really simple, there are only 2 syntax for accessing them:
// 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;
