var nums = [1,2,3,6,8,11];
var target = 10;

function getTwoNumSum(nums, target) {
  var i = 0, j = nums.length - 1;
  while(i < j) {
    if (nums[i] + nums[j] > target) {
      j--;
    } else if (nums[i] + nums[j] < target) {
      i++;
    } else {
      return [i + 1, j + 1];
    }
  }
  return [-1, -1];
}

console.log('最终值为 > ', getTwoNumSum(nums, target));
