Javascript """ 之间的正则表达式文本

Question

如何在 javascript 的正则表达式中获取"""和"""之间的文本？

例子：

"""hello world"""应该给hello world

""" hi """ """world"""应该给[hi, world]

Answer 1

干得好：

(?<=""") ?\w+ ?( \w+)*(?=""")

解释

(?<=""")   --->   make sure three quotes appear prior to a word
 ?         --->   optional space
\w+        --->   match any word characters
( \w+)*    --->   match 0 or more spaced out words
(?+""")    --->   ensure that there's following close quotes

在这里看到它的实际效果

Answer 2

不确定 OP 是否仍在寻找答案，但您应该尝试：

/"""([^"""]+)"""/g

这将匹配""" hi """ """world""" """hello world"""甚至"""I've bought a phone that costs $1000.00"""

Answer 3

以下 JavaScript 正则表达式应提取三重双引号之间的所有字符串：

var regexp = /"{3}([^"]*?)"{3}/g;

 const regex = /"{3}([^"]*?)"{3}/g; const str = `"""hello world""" """ hi """ """world""" """ hi """ """world""" hello world How are you? `; let m; while ((m = regex.exec(str)) !== null) { // This is necessary to avoid infinite loops with zero-width matches if (m.index === regex.lastIndex) { regex.lastIndex++; } // The result can be accessed through the `m`-variable. m.forEach((match, groupIndex) => { console.log(`Found match, group ${groupIndex}: ${match}`); }); }
