Question

I have the following JS code:

var Item = function ()
{
    this.property = '';
    this.myfunction = function ()
    {
        var value = this.property;
    };

};

however, this does not point to the defining class so value doesn’t get anything.

how do I access this.property from inside my function?

Answer 1

You need to create a closure which captures the value of parent scope’s this:

var Item = function ()
{
    this.property = '';
    var self = this;
    this.myfunction = function ()
    {
        var value = self.property;
    };

};

Update: As others have pointed out, this closure is not needed when Item is used as a constructor (new Item()). Noting it here for future reference.
