求两个数之间的所有奇数

<script>
    var tx1 = document.getElementById("txt1");
    var tx2 = document.getElementById("txt2");
    var tx3 = document.getElementById("txt3");
    var btn = document.getElementById("but");

    btn.onclick = function(){
        var a = Number(tx1.value);
        var b = Number(tx2.value);
        get(a,b)
    }

    function get(n, m) {
        if (n > m) {
            var k = n;
            n = m;
            m = k;
        }//判断大小交换位置

        for (var s = n; s <= m; s++) {

            for (var b = n; b <= m; b++) {

                if (("" + s + b) % 2 !== 0 && s != b) {

                    console.log("" + s + b);

                }
            }
        }
    }
    get(1,4);
