从数组中提取特定信息

I have data two sets of data as follows: "One.Two.Three.Four" "One.Two.Three.1.Four"

我有两组数据如下:“一、二、三。”四个One.Two.Three.1.Four”

The first three parts are fixed and the remaining can extend to as many as possible. I am trying to build an object where I want to split and combine whatever is present after three into an object.

前三部分是固定的，其余部分可以扩展到尽可能多的地方。我正在尝试构建一个对象，在这个对象中，我想要拆分和合并任何在三个之后出现的对象。

var split = samplestr.split('.');
var finalarray = [];
if(split.length>4)
{
  finalarray[0] = split[0];
  finalarray[1] = split[1];
 finalarray[2] = split[2];
  finalarray[3] = split[3]+"."split[4];
}

I need to generalise this such that even if the string is of the form

我需要推广这样的东西，即使字符串是形式。

"One.Two.Three.1.2.3.Four"

finalarray[3] = 1.2.3.Four;

Any hints on generalising this?

有什么建议吗?

2 个解决方案

#1

With Array#shift and Array#join.

与数组#转变和数组#加入。

var split = samplestr.split('.');
var finalarray = [];
if(split.length > 4) {
    finalarray[0] = split.shift();
    finalarray[1] = split.shift();
    finalarray[2] = split.shift();
    finalarray[3] = split.join(".");
}

#2

simply replace

简单的替换

finalarray[3] = split[3]+"."split[4];

with

与

finalarray[3] = split.slice(3).join(".");
