javascript - 在索引数组中提取 int 值？

Question

所以我对我用html制作的这个分数表有疑问。

var puntenTelling= new Array(3,4,2,1,5);
var teamNamen = new Array(puntenTelling[0]+"Team1", puntenTelling[1]+"Team2",puntenTelling[2]+ "Team3", puntenTelling[3]+"Team4", puntenTelling[4]+"Team5");
puntenTelling.sort(function(a, b){return b-a});
teamNamen.sort();
teamNamen.reverse();

for (var i=0; i<5; i++) {
  document.write("<tr><td>" + teamNamen[i]);
  document.write("<td>" + puntenTelling[i] + "</td></tr>");
}

基本上这给了我一个排序表，它按点排序，并按链接到点的团队名称排序。 我必须在 teamNames 数组中包含点 (puntenTelling)，否则我无法按照对点进行排序的方式对其进行排序。

现在我打印出来是这样的:

Teamname  Points
5Team5       5
4Team2       4
3Team1       3
2Team3       2
1Team4       1

我只想去掉“5,4,3,2,1” 在“Team5，Team2”等之前

我该怎么做？

您连接点和团队名称的方法不是很干净和可靠(名为 1860 Munich 的团队怎么样？)它的要点，并使用这个数组:

var teamsWithPoints = [
    { name: "team1", points: 3 },
    { name: "team2", points: 4 },
    { name: "team3", points: 2 },
    { name: "team4", points: 1 }
  ];

teamsWithPoints.sort(function(a, b) { return b.points - a.points });

document.write("<table>");
teamsWithPoints.forEach(function(team) {
  document.write("<tr>");
  document.write("<td>" + team.name);
  document.write("<td>" + team.points);  
});
