I have a string of the format: string:num where num is any number but string is a known string that I need to match on. I'd like to have this in an if statement as:
if( it matches 'string:' followed by a number) {
//do something
}
You want ...
if (stringYouHave.match(/^string:([0-9]+)$/)) {
// do something
}
This includes:
^ beginning of the stringstring: the literal string: you mentioned(.....) This subexpression, which you can refer to later if you need to know which number is in the string (though in this particular case, you could also just replace 'string:' with '')[0-9] a character between 0 and 9 (i.e., a digit)+ Must have at least one of those (i.e., digits mentioned above), but can have any number$ end of the string
