suppose that, i've this string:
google.com/:id/:category
how can i extract only id and category from this string?
i should use regex
this match doesn't work:
match(/\/:([a-zA-Z0-9]*)/g);
You may try the following:
var url = "google.com/:id/:category";
var parts = url.match(/(?<=\/:)[a-zA-Z0-9]+/g);
console.log(parts);This approach uses the positive lookbehind (?<=\/:) to get around the problem of matching the unwanted leading /: portion. Instead, this leading marker is asserted but not matched in the version above.
Well, capture groups are ignored in match with /g. You might go with matchAll like this:
const url = "google.com/:id/:category"
const info = [...url.matchAll(/\/:([a-zA-Z0-9]*)/g)].map(match => match[1])
console.log(info)Credit: Better access to capturing groups (than String.prototype.match())
