我有以下数组
var category = ['Guitar', 'Bass', 'Amps'];
var platform_a = ['platform-a1','platform-a2','platform-a3'];
var platform_b = ['platform-b1','platform-b2','platform-b3'];
var platform_c = ['platform-c1','platform-c2','platform-c3'];
我想把它们转换成一个看起来像这样的json
{
"Guitar":["platform-a1","platform-a2","platform-a3"],
"Bass":["platform-b1","platform-b2","platform-b3"],
"Amp":["platform-c1","platform-c2","platform-c3"]
}
我该怎么做?我必须在纯JavaScript中执行此操作

让我们为您的案例提供三种不同的方法:
第一个
如果您只想用数据创建json对象,请尝试:
http://jsfiddle.net/csdtesting/tap2xom9/
var platform_a = ['platform-a1', 'platform-a2', 'platform-a3'];
var platform_b = ['platform-b1', 'platform-b2', 'platform-b3'];
var platform_c = ['platform-c1', 'platform-c2', 'platform-c3'];
var category = ['Guitar', 'Bass', 'Amps'];
var obj = {
Guitar: platform_a,
Bass: platform_b,
Amps: platform_c
};
document.write(JSON.stringify(obj));

第二
如果你想动态创建它,请执行以下操作:
http://jsfiddle.net/csdtesting/tap2xom9/
var category = ['Guitar', 'Bass', 'Amps'];
var platform_a = ['platform-a1', 'platform-a2', 'platform-a3'];
var platform_b = ['platform-b1', 'platform-b2', 'platform-b3'];
var platform_c = ['platform-c1', 'platform-c2', 'platform-c3'];
var FinalObject = {};
FinalObject[category[0]] = platform_a;
FinalObject[category[1]] = platform_b;
FinalObject[category[2]] = platform_c;
document.write(JSON.stringify(FinalObject));

<强>最后强>
如果你想要更有活力,那么试试这个:
http://jsfiddle.net/csdtesting/kqwz72os/
var FinalObject = {};
var category = ['Guitar', 'Bass', 'Amps'];
var platforms = {
platform_a: ['platform-a1', 'platform-a2', 'platform-a3'],
platform_b: ['platform-b1', 'platform-b2', 'platform-b3'],
platform_c: ['platform-c1', 'platform-c2', 'platform-c3']
};
for (var i = 0; i < category.length; i++) {
FinalObject[category[i]] = platforms[Object.keys(platforms)[i]];
}
document.write(JSON.stringify(FinalObject));

希望这有帮助!

这里没有合理的捷径。你只需要手动完成:
var jsonString = JSON.stringify({
"Guitar": platform_a,
"Base": platform_b,
"Amp": platform_c
});
