Question

我有这个字符串

var str = "394987011016097814 1d the quick brown fox jumped over the lazy dog";

..而我正试图让它成为这个数组

[
    "394987011016097814",
    "1d",
    "the quick brown fox jumped over the lazy fox",
]

我已经看到了这个答案Split string on the first white space occurrence，但这仅适用于第一个空格。

Answer 1

使用拆分和联接进行解构

var str = "394987011016097814 1d the quick brown fox jumped over the lazy fox";
var [str1, str2, ...str3] = str.split(' ');
str3 = str3.join(' ');
console.log([str1, str2, str3])

Answer 2

来源：Split a string only the at the first n occurrences of a delimiter

var string = 'Split this, but not this',
    arr = string.split(' '),
    result = arr.splice(0,2);

result.push(arr.join(' ')); // result is ["Split", "this,", "but not this"]

alert(result);

Answer 3

您可以先在所有空间上分割，然后取两个值并合并其余的值。

var str = "394987011016097814 1d the quick brown fox jumped over the lazy fox";
let op = str.split(/[ ]+/g)

let final = [...op.splice(0,2), op.join(' ')]

console.log(final)

Answer 4

以这种方式使用正则表达式^(\d+)\s(\S+)\s(.*)

var re = new RegExp(/^(\d+)\s(\S+)\s(.*)/, 'gi');
re.exec('394987011016097814 1d the quick brown fox jumped over the lazy fox');

var re = new RegExp(/^(\d+)\s(\S+)\s(.*)/, 'g');
var [, g1, g2, g3] = re.exec('394987011016097814 1d the quick brown fox jumped over the lazy fox');
console.log([g1, g2, g3]);

Answer 5

您可以通过编写一些代码来实现：

const str = "394987011016097814 1d the quick brown fox jumped over the lazy fox";

const splittedString = str.split(' ');
let resultArray = [];
let concatenedString = '';

for (let i = 0; i < splittedString.length; i++) {
    const element = splittedString[i];
    if (i === 0 || i === 1) {
        resultArray.push(element);
    } else {
        concatenedString += element + ' ';
    }
}

resultArray.push(concatenedString.substring(0, concatenedString.length - 1));

console.log(resultArray);

// output is: 
// [ '394987011016097814',
// '1d',
// 'the quick brown fox jumped over the lazy fox' ]

let str = "394987011016097814 1d the quick brown fox jumped over the lazy fox";
let arr = [];             
str = str.split(' ');     
arr.push(str.shift());    
arr.push(str.shift());    
arr.push(str.join(' '));
console.log(arr);
