Javascript /// <field type=?> used to define properties for individually customized objects

Exploring the XML javascript comment syntax in Visual Studio and encountering some confusion. Specifically, I have a query regarding custom types. For example, consider a custom type like...

namespace.types.User = function(_id, _name) {
    /// <field name="id" type="Number">ID of the user</field>
    /// <field name="name" type="String">Name of the user</field>
    this.id = _id;
    this.name = _name;
};

If I wish to refer to that type in a <field> later on, I would write something like...

namespace.session = function() {
    /// <field name="CurrentUser" type="namespace.types.User">The current User of the session</field>
    this.CurrentUser = new namespace.types.User('foo', 'bar');
};

However, despite this setup, Intellisense in Visual Studio provides the description of .CurrentUser but does not suggest .id or .name properties. It behaves as if it's a generic object without any specific type information.

Is there a way to enhance Visual Studio's intelligence to recognize the detailed description of custom objects?

Answer №1

Consider including XML comments for the parameters in the function signature.

namespace.types.User = function(_id, _name) {
   /// <param name="_id" type="Number" /></param>
   /// <param name="_name" type="String" /></param>
}

Using ///<field></field> syntax may not enhance intellisense for field values, as it primarily detects intellisense from assignment. Without knowing the types of incoming parameters, they may not be passed onto the fields.

One would assume that adding ///<field></field> would override the type intellisense for field. Especially if experienced with IDEs or tools that support intellisense from code comments. However, this does not currently seem the case in VS 2010.

Furthermore, it is advisable to avoid using "namespace" as a variable or identifier, even if it is for illustrative purposes or stands in for the actual namespace. "Namespace" is a reserved keyword in JavaScript (although some, like Mozilla, prefer "package").
