Question

我有一个如下所示的字符串：

var String = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string without comma,xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string,with comma,xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string,xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string without comma,xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string , with comma,xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:String,with comma"

其中xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx代表字母数字生成的Id，冒号之后是与该Id相关的字符串。字符串可以是逗号或不带逗号的字符串。我想要的是我想要分割字符串等我得到一个带ID的数组：它对应的字符串，如下所示。

["xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string without comma","xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string,with comma","xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string","xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string without comma", "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:some string , with comma","xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:String,with comma"]

我如何实现

我使用了javascript split函数，其中我用逗号分隔字符串，后跟36个字符（用于ID）和冒号。

String.split(/,(?=.{36}:)/);

PS：我道歉，因为我以前无法以正确的方式提问。希望这次人们能理解。

Answer 1

您可以使用逗号String#split并预览数字和冒号。

var x = "123456:a,b,c,435213:r,567876:e,363464:t,y,u";
    array = x.split(/,(?=\d+:)/);

console.log(array);

对于字母数字值

var x = "1A3456:a,b,c,43Y213:r,567W76:e,363x64:t,y,u";
    array = x.split(/,(?=[a-z0-9]+:)/i);

console.log(array);

Answer 2

您可以使用方法.split()。我使用＆＃34; $＆＃34;作为分裂符号代替＆＃34;，＆＃34;因为我以为你想保留它们。

＆＃13;

var values = "123456:a,b,c$435213:r$567876:e$363464:t,y,u".split("$");
var x = values[0];

console.log(values)

＆＃13;

用逗号和冒号分割字符串
