为数组中的单个数据创建另一个数据

Question

我正在做一个匹配系统，其中将匹配 2 个具有相同级别的玩家（加入 1 个数组）。我的目标是如何让没有匹配的玩家在数组中有第二个数据？

Example: EntryID: “15”, player: ”testing11”, level: ”3”
         EntryID: ”nm”, player: ”nm”, level: ”nm”;

我提供的例子是当一个玩家没有匹配时，应该有另一个数据产生“nm”，这意味着没有匹配。

我提供了我的目标图像，以便更好地可视化我的问题和目标。非常感谢

脚本：

let ajaxResult = []; // the pushed data will be saved here
let save_method;
let table;
let base_url = "<?php echo base_url();?>";
let result = [];
var html = "";




// This is where the same level will be matched
const combine = (source) => {
  return source.reduce((acc, curr) => {
    if (acc[curr.level]) {
      const levelArr = acc[curr.level];
      const last = levelArr[levelArr.length - 1];
      if (last.length === 2) {
        levelArr.push([curr])
      } else {
        last.push(curr)
      }
    } else {
      acc[curr.level] = [
        [curr]
      ];
    }
    return acc;
  }, {})
};



// I'm removing the duplicates here. Test 1 vs Test 1 shouldn't be possible
function removeDuplicates(result) {
   return Object.values(result.reduce((acc, curr) => { 
       acc[curr.player] = acc[curr.player] || curr;
       return acc;
   }, {}))
}



const uniquePlayers = removeDuplicates(result);

如果您的目标只是为 nm 添加输入，您可以检查 JSON 数组 长度是否为 1。如果它的 1 则意味着只找到一个匹配项，因此您可以在 val.forEach(.. 内添加具有 nm 值的其他匹配项。

演示代码:

//just for demo....
var data = {
  "data2": [{
    "entryID": "15",
    "player": "testing11",
    "level": "3"
  }, {
    "entryID": "13",
    "player": "testing8",
    "level": "1"
  }, {
    "entryID": "4",
    "player": "testing4",
    "level": "2"
  }, {
    "entryID": "3",
    "player": "testing3",
    "level": "2"
  }, {
    "entryID": "1",
    "player": "testing1",
    "level": "1"
  }, {
    "entryID": "5",
    "player": "testing5",
    "level": "5"
  }]
}

const combine = (source) => {
  return source.reduce((acc, curr) => {
    if (acc[curr.level]) {
      const levelArr = acc[curr.level];
      const last = levelArr[levelArr.length - 1];
      if (last.length === 2) {
        levelArr.push([curr])
      } else {
        last.push(curr)
      }
    } else {
      acc[curr.level] = [
        [curr]
      ];
    }
    return acc;
  }, {})
};

function removeDuplicates(result) {
  return Object.values(result.reduce((acc, curr) => {
    acc[curr.player] = acc[curr.player] || curr;
    return acc;
  }, {}))
}


result = combine(removeDuplicates(data.data2));
var keys = Object.keys(result)
var html = ""
for (var i = 0; i < keys.length; i++) {
  result[keys[i]].forEach(function(val) {
    var length_ = val.length; //length of the json aray inside obj
    val.forEach(function(value, index) {

      var entryIDs = index == 0 ? "entryIDM[]" : "entryIDW[]"
      var players = index == 0 ? "playerM[]" : "playerW[]"
      var levels = index == 0 ? "levelM[]" : "levelW[]"
      html += `<input type="text" name="${entryIDs}" value="${value.entryID}"> 
                 <input type="text" name="${players}" value="${value.player}">
                 <input type="text" name="${levels}" value="${value.level}">`

      //if length is only one
      if (length_ == 1) {
        //just add inputs with nm..
        html += `<input type="text" name="entryIDW[]" value="nm"> <input type="text" name="playerW[]" value="nm"><input type="text" name="levelW[]" value="nm">`

      }

    })
  })
}
document.getElementById("result").innerHTML = html
