To do a case-insensitive string replacement in JavaScript call the `String.replace` method and set the `ignore` flag on the first parameter.
QString QString::replace(const QString &before, const QString &after, Qt::CaseSensitivity cs = Qt::CaseSensitive) 其中,before表示要被替换的子串,after表示替换后的子串,cs表示匹配时是否区分大小写。如果cs为Qt::CaseSensitive,则表示区分大小写;如果cs为Qt::CaseInsensitive,则表示不区分大小写。 replace...

The Replace function is case-sensitive by default (using vbBinaryCompare). If you want case-insensitive replacements, use the vbTextCompare option for the compare parameter. The Replace function returns a modified string as the result. You need to assign the result back to a variable or the ori...
replace方法和replaceAll方法都是区分大小写的。如果需要不区分大小写的替换操作,可以使用正则表达式的标志参数指定为Pattern.CASE_INSENSITIVE。 如果字符串中包含特殊字符,例如正则表达式中的元字符(如.、*、+等),在进行替换时需要进行转义。可以使用Pattern.quote方法来实现转义。
