Adding a function to a JavaScript object

Question

In my JavaScript I have an object instance called "View". I want to add a function to this object. The function looks something like

function csiSelectValueRestriction (columnName) {
    //... <a rather long and involved function>
}

Ultimately I want to be able to use the function in the following way:

var result = View.csiSelectValueRestriction ("bldgs");

What is the simplest way to accomplish this?

Just assign the function to the property;

View.csiSelectValueRestriction = csiSelectValueRestriction;

This should work if you want to add a function to an existing instance

View['csiSelectValueRestriction'] = function (columnName) { ... ... }

var View = {
   someProperty: 'someVal',
   csiSelectValueRestriction: function(columnName) {
        //JS logic
   }
};

or View.csiSelectValueRestriction = function(columnName) { ... }
