如何在新的JS哈希表中使用变量作为键

Question

Is there a way in javascript that I can use variables in new hashtables as keys

example

var key1 = "test1";
var key2 = "test2";

var table = { key1: true, key2: true };

But I would like the table to end up being

{ test1: true, test2: true }

You can use it by following example:

var key1 = "test1",
  key2 = "test2",
  table = {};

table[ key1 ] = true;
table[ key2 ] = true;

console.log( table ); // { test1: true, test2: true }

See jsFiddle demo .

So accessing them would be like

console.log( table.test1 );

or

console.log( table[ key1 ] );

or

console.log( table[ "test1" ] );
