How to create a jquery array that contains variables as key

Question

I have this array

query = { x: { y: z } }

I tried like this but jquery makes my vars as constant key

var x = "one";
var y = "two";
var z = "three";

var query = { x: { y: z } }

Your question is not at all clear. What are you trying to do? — Rory McCrossan, Dec 01 '14 at 09:22

You can use bracket notation to achieve that.

var query = {}, obj = {}; // objects
obj[y] = z; 
query[x] = obj;
console.log(query);

Try this:-

var query; 
query[x]={};
query[x][y]=z;

There's a syntax error. You should test your code before posting an answer. – pawel Dec 01 '14 at 09:31

It seems you want to create a hashtable and use some variables as keys. You can do this by creating a hashtable and then setting values as follows

var query = {},
    x = 'one',
    y = 'two',
    z = 'three';

query[x] = {};
query[x][y] = z
