Dynamically name a JSON property

Question

I've been trying to create a dynamically named JSON property but I keep hitting on errors. Honestly I don't know if this is possible to achieve with Javascript. Anyway here is my problem.

Let's suppose I'm creating a JSON object like the following code:

var DTO = { 'NewObject' : GetFormData() };   var DTO = { 'UpdateObject' : GetFormData() };   var DTO = { 'DelObject' : GetFormData() };   

Now what I've been trying to do is to dynamically name the JSON property because with something like 'New' + ClassName (ClassName being a var with a string value) but it gives me a syntax error. Is there a way to do this to become something like:

var DTO = { 'New' + ClassName : GetFormData() };   var DTO = { 'Update' + ClassName : GetFormData() };   var DTO = { 'Delete' + ClassName : GetFormData() };   

I really appreciate your help. Thanks.

Answer 1

Would this suit your needs ?

var DTO = {}; DTO['New' + ClassName] = GetFormData(); 

Answer 2

With ECMAScript 6, you can use computed property names in object property definitions.

For example, you can simply write:

var DTO = { ['New' + ClassName] : GetFormData() };
