正則表達(dá)式匹配星號、波浪號、破折號和方括號

正則表達(dá)式匹配星號、波浪號、破折號和方括號

不負(fù)相思意 2021-10-14 16:50:21
我一直在嘗試編寫一個(gè)正則表達(dá)式來匹配星號、波浪號、破折號和方括號。我擁有的：const str = "The] quick [brown] fox **jumps** over ~~the~~ lazy dog --- in the [woods";console.log(str.match(/[^\]][^\[\]]*\]?|\]/g));// [//     "The]",//     " quick ",//     "[brown]",//     " fox **jumps** over ~~the~~ lazy dog --- in the ",//     "[woods"// ];我想要的是：[    "The]",    " quick ",    "[brown]",    " fox ",    "**jumps**",    " over ",    "~~the~~",    " lazy dog ",    "---",    " in the ",    "[woods"];編輯：字符串的更多示例/組合是："The] quick brown fox jumps [over] the lazy [dog"// [ "The]", " quick brown fox jumps ", "[over]", " the lazy ", "[dog" ]"The~~ quick brown fox jumps [over] the lazy **dog"// [ "The~~", " quick brown fox jumps ", "[over]", " the lazy ", "**dog" ]編輯2：我知道這很瘋狂，但是："The special~~ quick brown fox jumps [over the] lazy **dog on** a **Sunday night."// [ "The special~~", " quick brown fox jumps ", "[over the]", " lazy ", "**dog on**", " a ", "**Sunday night" ]

您可以使用此正則表達(dá)式進(jìn)行更多更改以包含您想要的匹配項(xiàng)：


const re = /\[[^\[\]\n]*\]|\b\w+\]|\[\w+|\*\*.+?(?:\*\*|$)|-+|(?:^|~~).+?~~|[\w ]+/mg;

const arr = [

'The special~~ quick brown fox jumps [over the] lazy **dog on** a **Sunday night.',

'The] quick brown fox jumps [over] the lazy [dog',

'The] quick [brown] fox **jumps** over ~~the~~ lazy dog --- in the [woods'

];


var n;

arr.forEach( str => {

  m = str.match(re);

  console.log(m);

});

您可以使用此正則表達(dá)式來拆分字符串。它在分隔符（**,~~或[]）之一與匹配的分隔符或字符串的開始/結(jié)束之間拆分文本上的字符串；或在一系列連字符 ( -) 上。它使用捕獲組來確保正則表達(dá)式匹配的字符串出現(xiàn)在輸出數(shù)組中：


((?:\*\*|^)[A-Za-z. ]+(?:\*\*|$)|(?:~~|^)[A-Za-z. ]+(?:~~|$)|(?:\[|^)[A-Za-z. ]+(?:\]|$)|-+

const re = /((?:\*\*|^)[A-Za-z. ]+(?:\*\*|$)|(?:~~|^)[A-Za-z. ]+(?:~~|$)|(?:\[|^)[A-Za-z. ]+(?:\]|$)|-+)/;

const str = [

  'The] quick [brown] fox **jumps** over ~~the~~ lazy dog --- in the [woods',

  'The] quick brown fox jumps [over] the lazy [dog',

  'The~~ quick brown fox jumps [over] the lazy **dog',

  'The special~~ quick brown fox jumps [over the] lazy **dog on** a **Sunday night.'];


str.forEach(v => console.log(v.split(re).filter(Boolean)));

.as-console-wrapper { max-height: 100% !important; top: 0; }
