Javascript，合并数组元素

Question

我一直在寻找一种合并数组元素的方法。

所以我的数组的格式为[id1:port1,id2:port2,id1:port3,id2:port4,id5:port5...]，其中每个元素都有2个部分。 id 部分不是唯一的。我尝试合并的是创建一个新数组，其中包含 [id1#port1:port3,id2#port2:port4,id5#port5]

等数据

我尝试了下面的代码，但它并没有让我走得太远。有高手可以帮帮我吗？

var orinString = "id1:port1,id2:port2,id1:port3,id2:port4,id5:port5";

var newArray1 = orinString.split(",");
var newArray2 = orinString.split(",");
var newArray3 = [];

for (x=0; x<=newArray1.length-1; x++) {
  for (y=0; y<= newArray2.length-1; y++) {
    if ((newArray1[x].split(":")[0] == newArray2[y].split(":")[0]) && (newArray1[x].split(":")[1] != newArray2[y].split(":")[1])) {
      newArray3.push(newArray1[x].split(":")[0] +"#"+ newArray1[x].split(":")[1]);
    }
  }
}

for (z=0; z<=newArray3.length; z++) {
  gs.log("show me the result " +newArray3[z]);
}

是你想要的吗:

var orinString = "id1:port1,id2:port2,id1:port3,id2:port4,id5:port5";
var arr1 = orinString.split(",");
var temp= ""; 
var newStr = "";
arr1.sort();
for(i=0; i< arr1.length; i++) {
    var item = arr1[i].split(':');
    if(item[0] !== temp || temp === "") {
        newStr += "," + item[0] + "#" + item[1];
    } else {
        newStr += ":"+item[1];
    }
    temp = item[0];
}
console.log(newStr.substring(1));
