在子参数方法中如何使用此关键字到达元素？

Question

I have an object like this

function myObject(){
    this.$domElement = $('#apple');
    this.name = 'apple';
    this.color = 'green';
    this.price = '200';

    this.show = function(){
       this.$domElement.show()
    }
}

Now I want to add a new method to this object like this

this.setCss = {
    position : function(){
        //...
    },

    opacity : function(){
        //...
    },

    border : function(){
        //...
    }
}

Now, my question : How can I reach my object again with this keyword.

The final code I am expecting is something like this. If possible...

function myObject(){
    this.$domElement = $('#apple');
    this.name = 'apple';
    this.color = 'green';
    this.price = '200';
    this.show = function(){
       this.$domElement.show()
    }
    this.setCss = {
        position : function(){
        //...this.$domElement.css({top:10,left:20})
        },
        opacity : function(){
        //...this.$domElement.css({opacity:.5})
        },
        border : function(){
        //...this.$domElement.css({border:'1px solid red'})
        }
    }
}

try this

 function myObject(){
   //init
   var me = this;

    this.$domElement = $('#apple');
    this.name = 'apple';
    this.color = 'green';
    this.price = '200';

    this.show = function(){
       //use
       me.$domElement.show()
    }
}

var obj = new myObject();
obj.show();
