Dear all, it's my simple JS program. I can't figure out that why can't i stop the loop by using "guess==null". Please help!!

var target = prompt("Please enter a number small than 50:");

    var guess = "";
    var time = 0;

    /\*
    var guess2 = prompt("111");
    var guess3 = window.prompt("222",guess3);
    document.write(typeof(guess));
    document.write(typeof(guess2));
    document.write(typeof(guess3));
    \*/

    do{
        guess = prompt("Please Guess:");
        if(guess == target || guess == null){
            break;
        }

        if(guess < target){
            alert("bigger!");
            time++;
            continue;
        }else{
            alert("smaller!");
            time++;
            continue;
        }
    }while(true)

    if(guess==null){
        document.write("the answer is:"+target);
    }else{
        document.write("Good!共猜了:"+(time+1));
    }

/*
Dear all,

<script>
function Array2D(x,y){
this.length = x*y;
this.x = x;
this.y = y;

        for(var i=0 ; i<this.length ; i++){
            this\[i\] = null;  
        }
        this.get = function(x,y){ 
            return this\[x\*this.x+y\];
        }
        this.set = function(x,y,value){ 
            this\[x\*this.x+y\] = value;

        }
    }

</script>

Uncaught TypeError: Cannot read property 'set' of undefined

How does it happen?and what should i do to avoid this?
