function bubbleClick() {
    var str = "50,1,4,6,9,76,43,22,2,44,7,66";
    bubble(str);
}

function bubble(str) {
    var a = new Array();
    a = str.split(‘,‘);//字符串数组，
    //var a = [50, 1, 4, 6, 9, 76, 43, 22, 2, 44, 7, 66]
    var tmp = 0;
    for (var i = 0; i < a.length; i++) {
        for (var j = 0; j < a.length - i - 1; j++) {
            //两个相邻的比较大小，把小的留下，
            if (a[j] > a[j + 1]) {
                tmp = a[j + 1];
                a[j + 1] = a[j];
                a[j] = tmp;
            }
        }
    }
    console.log(a);
