在地图存储中映射

Question

如何在javascript中将地图存储在地图中？

var data = {};
data['key'] = {'val1', 'val2'};

我收到有关错误ID的错误.

Answer 1

你要么需要一个阵列......

var data = {};
data['key'] = ['val1', 'val2'];  // store an Array at data.key

data.key[0]; // 'val1'

...或对象中的值的键...

var data = {};
data['key'] = {key1:'val1', key2:'val2'};  // store an Object at data.key 

data.key.key1;  // 'val1'
