    var nums = new Array();
    for (var i=0; i<fields.length; i++) nums.push(parseFloat(fields[i].value));
    for (var i=0; i<nums.length-1; i++) {
        for (var j=i+1; j<nums.length; j++) {
            if (nums[i] > nums[j]) {
                var tmp = nums[i];
                nums[i] = nums[j];
                nums[j] = tmp;
            }
        }
    }
    for (var i=0; i<nums.length; i++) fields[i].value = nums[i];
    return false;
}

function init() {
    var fields = document.getElementsByTagName("input");
    for (var i=0; i<fields.length; i++) {
        fields[i].value = Math.floor(Math.random() * 201 - 100);
    }
    document.getElementById('btnSort').onclick = function() { return sortme(); };
}

window.onload = init;
