Random selection, by definition, will repeat randomly.

However, you can build an array containing each of your numbers and then shuffle the array, producing a random order of numbers without repetition.

var nums = [], i;
for( i=1; i<=45; i++) nums.push(i);
nums.sort(function(a,b) {return Math.random()-0.5;});
alert(nums.join(","));
