Say I have the following:
var a = '1',
b = 'foo';
How do I create an object using the above variables such that my object looks like this:
'1' => 'foo'
I'm trying to make this like an associative array. Furthermore, I want 1 to contain an array of objects. I have the variable that have the array of object; I just need to put it in 1.
Use an object literal:
var myObject = { "1" : "foo" };
or, if you want to create it from variables, create a new object then assign things.
var myObject = {};
myObject[a] = b;
Furthermore, I want 1 to contain an array of objects
JavaScript doesn't care what type the data is. b can be an array as easily as a string. (And you can use an array literal where you have a string literal in the short version)
var myObject = { "1" : [ 7, "foo", new Date() ] };
var testArray = [];, you can manipulate it with the form testArray[0] = 1; or testArray['1'] = 'foo'; or even testArray.bar = 'baz';.
oMyTest['1']['data'] = data;. The variable data is an object.
oMyTest['1'] is an object, that should just work.var obj = { '1' : 'foo' };
obj['1']; // returns 'foo'
or
var obj = { '1' : new Array() };
obj['1']; // returns an array
obj, which I doubt would be possible.To do literally what you asked:
var a = '1',
b = 'foo',
o = {};
o[a] = b;
Quentin has the rest of the answer.
An example of assigning an object to an object property:
var foo = {bar: 'baz'};
var obj = {foo: foo};
// or
// var obj = {};
// obj['foo'] = foo;
// or
// obj.foo = foo;
alert(obj.foo.bar); // baz
o to contain another object. Say I have the object data and want it in o['data'] - how do I do that?
