写一个 var lectures = [
{ code: 'comp211', dow: 2, start: 1000, end: 1130, room: 'A203' },
{ code: 'comp211', dow: 5, start: 1000, end: 1130, room: 'A318' },

function dayOfWeek(dow) {

关于code的排序(有字母和数字)
例如显示出来 就是像上面的排序 function ByCode(year){ returns a new array
given year, sorted by course code.}
另外一个市在写个时间的排序 function ByTime(year){ returns a new array
given year, sorted by date-of-week and start time of the lectures.}
JS?HTML?
------解决方案--------------------
if(**==1)
=是赋值,==才是判断,先这样改过来再测试

看不太懂你的问题。
如果是对lectures排序,那写两个排序函数就可以了:
function byCode() {
var resultArr = lectures.sort(codeSorter);
print(resultArr);
}
function byTime() {
var resultArr = lectures.sort(timeSorter);
print(resultArr);
}
function codeSorter(lectureA, lectureB) {
return lectureA.code - lectureB.code;
if ( lectureA.code< lectureB.code)
return -1;
if ( lectureA.code> lectureB.code)
return 1;
return 0;
}
function timeSorter(lectureA, lectureB) {
var dowResult = lectureA.dow - lectureB.dow;
if (dowResult != 0) {
