In a weird case of mine, I cannot use the built-in regexp in js when I try to inject js to WebView.
What could be my second best thing to use? I basically use regexp to detect:
line-feed(someString.match(/\n/))
cartridge return(someString.match(/\r/))
split string into words(manyWords.split(/\s+/))
But other ways to achieve regexps without js built-in regexp will be appreciated as well.
Use javascript's built-in string.prototype.indexOf and string.prototype.split, there's really no need for regex for those cases.
For line feed you can use someString.indexOf('\n') > -1
For cartridge return you can use someString.indexOf('\r') > -1
For splitting to words you can use manyWords.split(' ')
Incase you want the split a string that contains line breaks to words, you need to nest the split like this:
manyWords.split('\n').flatMap(function(line) { return line.split(' ');});
