javascript - 正则表达式根据多个单词的存在来选择句子

Question

我可以使用此正则表达式从单个单词中选择一个句子:

[^.]* word [^.]*\.

如何以条件方式根据两个或多个单词选择一个句子？

例如，如果存在单词 A 和(单词 B 或单词 C)，则选择句子。

假设单词A =“研究”，单词B =“建议”，单词C =“证据”，则以下句子将被选中，因为有 2 个单词匹配:

Our studies suggest that ACTN3 R577X genotype is a modifier of clinical phenotype in DMD patients.

但是下面这句话，因为它只匹配了一个单词，所以不会被选中:

Moreover, studies of the RR genotype have shown a downward linear trend with increased incidences of ankle sprain.

Answer 1

我会使用:

\bworda\b[^.!?]*\b(?:wordb|wordc)\b

如果句子包含 worda 和 wordb 或 wordc，则将匹配该句子> 如果没有标点符号分隔。

如果您想以任意顺序匹配单词:

^(?=[^.!?]*\bstudies\b)(?=[^.!?]*\b(?:suggest|evidence)\b)[^.!?]*\.$

var test = [
'Our studies suggest that ACTN3 R577X genotype is a modifier of clinical phenotype in DMD patients.',
'Moreover, studies of the RR genotype have shown a downward linear trend with increased incidences of ankle sprain.',
'Moreover, studies of the evidence of ankle sprain.',
'Moreover, evidence of the studies of ankle sprain.',
'Moreover, the incidences of ankle sprain.'
];
console.log(test.map(function (a) {
  return a+' :'+/^(?=[^.!?]*\bstudies\b)(?=[^.!?]*\b(?:suggest|evidence)\b)[^.!?]*\.$/i.test(a);
