JavaScript/jQuery 比较数组中的项目

Question

我想做的是比较数组中的项目以确定谁首先列出，为简单起见，在我看来，所有人员数据都存储在同一位置。我不知道分离这些数据是否会更容易或更有效。

这是数组，为了便于阅读而缩小了。

var People = [{
    "Name": "Person1",
    "SN": "1",
    "First": "5",
    "Second": "6",
    "Third": "11",
    "Fourth": "7",
    "Fifth": "8",
    "Sixth": "1",
    "Seventh": "10",
    "Eigth": "4",
    "Ninth": "3",
    "Tenth": "2",
    "Eleventh": "13",
    "Twelth": "9",
    "Thirteenth": "12",
    "RDO1": 2,
    "RDO2": 3
}, {
    "Name": "Person2",
    "SN": "2",
    "First": "6",
    "Second": "5",
    "Third": "10",
    "Fourth": "9",
    "Fifth": "7",
    "Sixth": "8",
    "Seventh": "1",
    "Eigth": "4",
    "Ninth": "3",
    "Tenth": "2",
    "Eleventh": "13",
    "Twelth": "11",
    "Thirteenth": "12",
    "RDO1": 2,
    "RDO2": 3
}, {
    "Name": "Person3",
    "SN": "3",
    "First": "6",
    "Second": "9",
    "Third": "7",
    "Fourth": "10",
    "Fifth": "8",
    "Sixth": "5",
    "Seventh": "4",
    "Eigth": "2",
    "Ninth": "3",
    "Tenth": "13",
    "Eleventh": "11",
    "Twelth": "12",
    "Thirteenth": "1",
    "RDO1": 4,
    "RDO2": 5
}];

我尝试了一堆嵌套的 if、for 循环和相互循环的函数，但没有成功。

所以我想要完成的是它会捕获“第一个”选择并与数组中的其他人进行比较，如果其他人有相同的“第一个”选择，它会比较 SN 号以查看哪个是更低。

因此，在上面的数组中，当代码到达 Person3 并且将“6”视为第一选择时，它会查看其他人是否将 6 作为第一选择，并注意到 Person2 也选择了它。然后它会比较 SN 编号，但不会将 6 给 Person3，因为 Person2 的编号较小，因此它会转到 Person3 的第二个编号，并再次进行相同的检查。

我已经为此绞尽脑汁有一段时间了，如果有人能阐明这一点，我将不胜感激。

function getPref(index1) {

var sNumb = dsobj[index1].SN;

for (var i = 0; i < dsobj.length; i++) {
if (i != index1) { // Ensure you aren't checking the same person
  if (sNumb > dsobj[i].SN) { //Check to see if the SN is lower than the person you are checking
if (dsobj[index1].First === dsobj[i].First) {
  if (dsobj[index1].Second === dsobj[i].Second) {

您可以调整以下功能以满足您的需求。我实现了它，用每个选择和每个选择名称的获胜者填充一个对象:

var winners = {};

function getChoiceWinner(choiceName) {
    for (var i = 0; i < People.length; i++) {
        var choice = People[i][choiceName];
        if(!winners[choiceName]) winners[choiceName] = {};
        winners[choiceName][choice] = People[i];
        for (var j = 0; j < People.length; j++) {
            if (winners[choiceName][choice][choiceName] == People[j][choiceName]) {
                winners[choiceName][choice] = People[j]["SN"] < winners[choiceName][choice]["SN"] ? People[j] : winners[choiceName][choice];
            }
        }
    }
}
