前两个空格的分割字符串

Question

我有这串

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",
]

我已经在第一个空格出现时看到了这个答案Split string，但这仅用于第一个空格。

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： 仅在定界符的前n个出现时分割字符串

 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

这样使用正则表达式^(\\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);
