// If you use unicode characters then this might be a better expression // thank you @Touffy let isMatch = new RegExp('(?:^|\\s)'+search, 'i').test(str); // i is case insensitive 在上面的代码中\b用于表示单词边界,因此glass是一个匹配项,但glassware将不匹配。i用于指定不区分大小写...
在这个例子中,str.toLowerCase()将待检查的字符串转换为小写,searchValue.toLowerCase()将子字符串也转换为小写,然后使用includes方法进行包含检查。由于两者都已转换为小写,因此可以忽略大小写的影响。 方法二:使用正则表达式 另一种方法是使用正则表达式,并设置忽略大小写的标志。在JavaScript中,正则表达式对象可以通过...
JavaScript RegExp(正则) 一、RegExp类型 g:表达全局(global)模式,即模式将被用于所有字符串,而非在发现第一个匹配项时立即停止 i:表示不区分大小写(case-insensitive)模式,即在确定匹配项时忽略模式与字符串的大小写 m:表示多行(multiline)模式,即在到达一行文本末尾时还会继续查找下一行中是否存在与模式匹配...
Here, we provided afromIndexof 1, which means the search for the "JavaScript" element will start at the second element of theprogrammingLanguagesarray. Since "JavaScript" is the first element, the method returnsfalse. FAQ Q: Can I use the includes() method with case-insensitive strings?

This specifies -j case insensitive searches with the Vim :grep command. For case sensitive searches, remove \ -j from grepprg. Multiple matches on the same line are listed in the quickfix window separately. If this is not desired, remove \ -u from grepprg. With this change, only the ...
