僅在一個數組中將不同元素轉換為數組

Question

我正在嘗試在單個數組中顯示多個元素。 （見示例）

但我不知道該怎么做......

謝謝你的幫助

我顯示我的腳本：

****Du code******

var color = [];
var risk = []; 
if(Operational.length == group.name.length){
  color = "green";
  risk = "Operational";
  console.log(group.name);
  // toto
  // tata
  // titi
}

if(Test.length > 0){
  color = "";
  risk = "";
}

 if(PartialOutage.length > 0){
   color = "orange"
   risk = "Partial";
 }

 if(MajorOutage.length > 0){
   color = "red";
   risk = "Major ";
 }
  var Group = new Array(color,risk,group.name);     
   Groups.push(Group);
   Groups.sort();
 }
});          
console.log(Groups);
}

**** Du code *****

實際結果 ：

[ [ 'green', 'Operational', 'toto' ],
[ 'green', 'Operational', 'tata' ],
[ 'green', 'Operational', 'titi' ],
[ 'orange', 'Partial', 'test' ],
[ 'red', 'Major ', 'test2' ] ]

預期結果 ：

[ [ 'green', 'Operational', 'toto,tata,titi' ],
[ 'orange', 'Partial', 'test' ],
[ 'red', 'Major ', 'test2' ] ]

看看這個。使用Array#reduce按預期格式重新創建最終數組值

1. 將第一個子數組推入新數組a
2. 然后用新創建的數組a循環每個b子數組
3. 使用forloop來打破循環
4. 如果新數組a存在子數組值。然后合並兩個數組並過濾重復//Check the comments in snippet

 var a = [ ['green', 'Operational', 'toto'], ['green', 'Operational', 'tata'], ['green', 'Operational', 'titi'], ['orange', 'Partial', 'test'], ['red', 'Major ', 'test2'] ]; a = a.reduce(function(a, b) { for (var i = 0; i <= b.length; i++) { var brk = false; var check = true; if (a.length > 0) { a.forEach(function(k, ind) { if (k.indexOf(b[i]) > -1) { //if contains same arg k = k.concat(b); //join two array var j = k.filter((l,n)=> k.filter(m=> m == l).length == 1).filter(o=>o) a[ind] = k.filter((l, n) => k.indexOf(l) != n); // filter duplicate a[ind].push(j.join(',')) brk = true; //then break the statement check = true; } else { check = false; //its not contain any arg direct push child into new array } }) if (brk) { break; } if (!check) { a.push(b) } } else { a.push(b); } } return a // recreated new array return }, []); console.log(a);
