JavaScript - 如何增加计数

Question

当我用当前下面的脚本给出一个 IP(10.31.68.0/22) 变量时，它将返回输出:10.31.68.1 - 10.31.68.10

var network = '10.31.68.0/22';
var IPstart = network.toString().substring(0,network.lastIndexOf('.')) + ".1";                      
var IPend = network.toString().substring(0,network.lastIndexOf('.')) + ".10";               
var excludename = IPstart+"-"+IPend;

我正在寻找如下所示的内容(输出)。 68 占位符应增加 +1，如下所示。

10.31.68.1 - 10.31.68.10

10.31.69.1 - 10.31.69.10

10.31.70.1 - 10.31.70.10

10.31.71.1 - 10.31.71.10

你需要用循环拆分和连接值

var network = '10.31.68.0/22';
    var IPstart = network.toString().substring(0,network.lastIndexOf('.')) + ".1";
    var IPend = network.toString().substring(0,network.lastIndexOf('.')) + ".10";
    var excludename = IPstart+"-"+IPend;
    var upToNumber=4;
    for(var i=0;i<upToNumber;i++){
        var res_ipstart = IPstart.split(".");
    res_ipstart[2]=parseInt(res_ipstart[2]) + i;
    var ip_start = res_ipstart.join(".");

        var res_ipend = IPend.split(".");
    res_ipend[2]=parseInt(res_ipend[2]) + i;
    var ip_end = res_ipend.join(".");

    var output=ip_start+"-"+ip_end;
    console.log(output);
    }
