我很难找到合并数组元素的方法。
所以我的数组格式为 [id1:port1,id2:port2,id1:port3,id2:port4,id5:port5 ...] ,其中每个元素有2个部分。 id部分不是唯一的。我试图整合的是创建一个新的数组将有 [id1#port1:port3,id2#port2:port4,id5#port5]
等数据我尝试过下面的代码,但它并没有让我走得太远。任何大师能帮助我吗?
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:
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));

解决此类问题的典型方法是
例如
var orinString = "id1:port1,id2:port2,id1:port3,id2:port4,id5:port5";
var idsAndPorts = orinString.split(",");
// Populate a key lookup
var hashTable = {};
idsAndPorts.forEach(function(s) {
var splitValue = s.split(':');
var key = splitValue[0];
var value = splitValue[1];
if(hashTable[key]) {
hashTable[key].push(value);
} else {
hashTable[key] = [value];
}
});
// Now convert it back into an array again
var finalArray = [];
for(var k in hashTable) {
finalArray.push(k + '#' + hashTable[k].join(','));
}
// View the results
finalArray.forEach(function(f) {
console.log(f);
})
这并不保证最终的数组会被排序,但如果您愿意,可以自己排序。
