To generate 6 2-digit number you need to loop six times. Below is the program to generate 6 2-digit number

document.getElementById("generateButton").onclick = function() {
                var msg = " ";
                for(var i = 0 ;i < 6 ; ++i) {
                var lottoNum = Math.floor(Math.random() * 89) + 10;
                msg += lottoNum + ",";
                }
                msg = msg.slice(0, -1);
                alert(msg);
            }

Here 10 to 89 is the desired range.

Where:

10 is the start number

89 is the number of possible results (10 + start (89) - end (10))

    document.getElementById("generateButton").onclick = function() {
                var msg = " ";                
                for(var i = 0 ;i < 6 ; ++i) {
                var lottoNum = Math.floor(Math.random() *89) + 10;
                msg += lottoNum + ", ";
                }
                msg = msg.slice(0, -1);
                alert(msg);
                }
