Does JQuery support Dictionaries (key, value) collection?

Question

Does JQuery support Dictionaries (key, value) collection ?

I would like to set the following data in a structure

[1, false] [2, true] [3, false] 

with the ability to add, lookup, delete and update.

Any help!

Answer 1

No, jQuery doesn't, but Javascript does.

Just use an object:

var dict = {   "1" : false,   "2" : true,   "3" : false };  // lookup: var second = dict["2"]; // update: dict["2"] = false; // add: dict["4"] = true; // delete: delete dict["2"];

jQuery, no. But JavaScript does. There are only two structures in JavaScript, arrays and objects.

Objects can be used as dictionary, where the properties are the "keys":

var dict = {     1: true,     2: true,     3: false }; 

Properties of objects can be either accessed with dot notation, obj.property (if the property name is a valid identifier, which a digit as used above is not) or with array access notation, obj['property'].
