Javascript 如何为csv字符串的精确连续元素设置序列？

我有一个

字符串

csv

包含端口代码和位置经纬度。我使用这些值在

googlemap

上绘制标记

例如csv字符串：

ANC|61.2181:149.9003,   
ANC|61.2181:149.9003,
TLK|62.3209:150.1066,
DNL|63.1148:151.1926,
DNL|63.1148:151.1926,
DNL|63.1148:151.1926,
TLK|62.3209:150.1066,
TLK|62.3209:150.1066,
ALE|60.9543:149.1599

ANC|61.2181:149.9003:1|2,
TLK|62.3209:150.1066:3,
DNL|63.1148:151.1926:4|5|6,
TLK|62.3209:150.1066:7|8,
ALE|60.9543:149.1599:9

我想为端口代码自动编号类似的端口代码序列，该序列用管道符号“|”分隔，端口代码与下一个元素完全连续

所需输出：

ANC|61.2181:149.9003,   
ANC|61.2181:149.9003,
TLK|62.3209:150.1066,
DNL|63.1148:151.1926,
DNL|63.1148:151.1926,
DNL|63.1148:151.1926,
TLK|62.3209:150.1066,
TLK|62.3209:150.1066,
ALE|60.9543:149.1599

ANC|61.2181:149.9003:1|2,
TLK|62.3209:150.1066:3,
DNL|63.1148:151.1926:4|5|6,
TLK|62.3209:150.1066:7|8,
ALE|60.9543:149.1599:9

任何使用

jquery/javascript/c#

？

的解决方案都可能有一种更简洁/更短的方法来实现这一点，但这里是使用javascript想到的第二种方法：

var input=“ANC 61.2181:149.9003，nANC 61.2181:149.9003，nTLK 62.3209:150.1066，nDNL 63.1148:151.1926，nDNL 63.1148:151.1926，nDNL 63.1148:151.1926，nTLK 62.3209:150.1066，nTLK 62.3209:150.1066，nTLK 62.3209:150.1066，NDNLE 60.1599”；
var output=input.split（“，\n”）.REDUCT（函数（p，c，i，a）{
如果（i==1）p+=“：1”；
返回p+（c==a[i-1]？“|”：”，\n“+c+”：”）+（i+1）；
});
控制台日志（输出）您可以制作类似的东西


var csv='ANC | 61.2181:149.9003，nANC | 61.2181:149.9003，nTLK | 62.3209:150.1066，nDNL | 63.1148:151.1926，nDNL | 63.1148:151.1926，nTLK | 62.3209:150.1066，nTLK | 62.3209:150.1066，nALE 1249:150.1066，nALE 1248:151.1926，NTL60.1599'，'；
//计数条目：
var结果=[]；
var j=-1；
var previous=“”；
对于（i=0；i这里是C#方法

public string[] data = { "ANC|61.2181:149.9003", "ANC|61.2181:149.9003", "TLK|62.3209:150.1066", "DNL|63.1148:151.1926", "DNL|63.1148:151.1926", "TLK|62.3209:150.1066", "TLK|62.3209:150.1066", "ALE|60.9543:149.1599", "DNL|63.1148:151.1926" };

int counter = 0;
var output = data.Select(x => new Tuple<string, int>(x, counter++))
           .GroupBy(x => x.Item1)
           .Select(h => h.Key + ":"+ string.Join("|", h.Select(x => x.Item2)));

public string[]data={“ANC | 61.2181:149.9003”、“ANC | 61.2181:149.9003”、“TLK | 62.3209:150.1066”、“DNL | 63.1148:151.1926”、“DNL | 63.1148:151.1926”、“TLK | 62.3209:150.1066”、“TLK | 62.3209:150.1066”、“ALE | 60.9543:149.1599”、“l 1248:151.1926”；
int计数器=0；
var output=data.Select（x=>newtuple（x，counter++）
.GroupBy（x=>x.Item1）
.Select（h=>h.Key+”：“+string.Join（“|”），h.Select（x=>x.Item2））；

输出将是
ANC 61.2181:149.9003:0 | 1，TLK 62.3209:150.1066:2 | 5 | 6，DNL | 63.1148:151.1926:3 | 8，ALE | 60.9543:149.1599:7
这不符合要求！它一定是类似于ANC | 61.2181:149.9003:0 | 1，。。。在设置顺序之前，请注意冒号（：），但我仍然感谢您的努力和时间来帮助我：）@SHEKHARSHETE np，简单地用冒号更改第一个Deliminer。答：更新请选择完美@A.T.！：）简单易懂。。！感谢您的帮助！：）
