How to access class member using "this" within method within a foreach loop.?

Question

I have an interesting problem. Following is my javascript code . when i run line this.data.splice(k,1); gives an error:"Cannot call method 'splice' of undefined ". I understand the issue as within the each loop this.data is not recognized because "this" means each row of the array. the question is how do i call this.data in this case. I tried tried passing the object by ref but it;s not working. I appreciate your help. thanks.

var Pastopts = {
    index: 0,
    data: [ "one", "two", "three", "four", "five", "six", "seven" ],
    addOpt: function() {
          var  i = 0;
        $.each(this.data, function(k, v) {
            i++;
            if (i < 6) {
                this.data.splice(k, 1);
            }
        });
     console.log(this.data);
    }
}

Pastopts.addOpt();

            i++;
