如何在数组javascript中拆分一个字符串？[副本]

Question

假设我们有以下字符串：

const str1 = 'aabbcc';
const str2 = 'aabbccaaddaaaaeeff';

我需要将它们分开，以获得以下结果:

mySplitFunction(str1, 'aa')//<--- ['aa','bbcc']
mySplitFunction(str1, 'bb')//<--- ['aa','bb', 'cc']
mySplitFunction(str2, 'aa')//<--- ['aa','bbcc', 'aa','dd', 'aa','aa', 'eeff']
mySplitFunction(str2, 'dd')//<--- ['aabbccaa','dd', 'aaaaeeff']

你会怎么做？

Answer 1

尝试:

const str1 = 'aabbcc';
const str2 = 'aabbccaaddaaaaeeff';
function mySplitFunction(str, delimiter){
  return str.split(new RegExp(`(${delimiter})`)).filter(s => s)
}

console.log(mySplitFunction(str1, 'aa'))
console.log(mySplitFunction(str1, 'bb'))
console.log(mySplitFunction(str2, 'aa'))
console.log(mySplitFunction(str2, 'dd'))

Answer 2

您可以在父级中使用分隔符，并过滤结果以忽略空字符串。

js prettyprint-override">const
    split = (string, separator) => string
        .split(new RegExp(`(${separator})`))
        .filter(Boolean),
    str1 = 'aabbcc',
    str2 = 'aabbccaaddaaaaeeff';

console.log(...split(str1, 'aa')); // ['aa','bbcc']
console.log(...split(str1, 'bb')); // ['aa','bb', 'cc']
console.log(...split(str2, 'aa')); // ['aa','bbcc', 'aa','dd', 'aa','aa', 'eeff']
console.log(...split(str2, 'dd')); // ['aabbccaa','dd', 'aaaaeeff']
