Does jQuery support a set of dictionaries (key, value)?

Question

Does jQuery support the Dictionaries collection (key, value)?

I would like to set the following data in the structure

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

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

Any help!

Answer 1

No, jQuery is not, but Javascript does.

Just use the 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"]; 

Answer 2

jQuery, no. But JavaScript does. JavaScript has only two structures: arrays and objects .

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

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

Object properties can either be obtained using dot notation, obj.property (if the property name is a valid identifier that uses a digit, as indicated above, or with an array access record, obj['property'] .

Answer 3

With pure JavaScript,

 var myDictionary = new Object(); myDictionary[1] = false; myDictionary[2] = true; myDictionary[3] = false; function look(i) { return myDictionary[i];} look(1); // will return false 

Answer 4

Yes, you can use an object for this:

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

Answer 5

You do not need separate dictionary classes, because Javascript objects act like dictionaries. See this:

 var userObject = {}; // equivalent to new Object() userObject["lastLoginTime"] = new Date(); alert(userObject["lastLoginTime"]);
