足球投注的可能性

Question

我想展示游戏可能结束的一切可能方式。

我有一个表单，用户可以在其中添加每个足球比赛。

现在我想在表格中显示比赛可能结束的所有可能方式。

e.g：

• team1 vs. team2，
• team3 vs team4

表（赢/输/抽奖）应该是这样的：

• team1，team3
• team1，team4
• team1，team3 team4 draw
• team2，team3
• team2，team4
• team2，team3 team4 draw
• team3，team1 team2 draw
• team4，team1 team2 draw
• team1 team2 draw，team3 team4 draw

Answer 1

以下示例尝试每个独特的团队组合，并列出每个可能结果的结果。

＆＃13;

var teams = [1, 2, 3, 4];
var fallouts = ["win", "lose", "draw"];
for (var ti1 = 0; ti1 < teams.length; ti1++) {
  var t1 = teams[ti1];
  for (var ti2 = ti1 + 1; ti2 < teams.length; ti2++) {
    if (ti1 == ti2) {
      continue;
    }
    var t2 = teams[ti2];
    for (var f = 0; f < fallouts.length; f++) {
      var fallout = fallouts[f];
      document.write("Team " + t1 + " matches against team " + t2 + " for a " + fallout + "<br/>")
    }
  }
}
