Match only unicode letters
(3 answers)
Closed 4 years ago.
I have this PHP regex:
/^[\p{L}\p{M}]+[\p{L}\p{M}\-\s]*$/u
and I want to convert it to jQuery. I tried multiple solutions that I found online, but nothing really worked. I tried using
new RegExp("/^[\p{L}\p{M}]+[\p{L}\p{M}\-\s]*$/u");
but that didn't help.
This is because \p{L} and \p{M} don't exist in the JavaScript RegEx engine. This answer provides solutions for matching Unicode categories: https://stackoverflow.com/a/26659285/1920035

Javascript, convert unicode string to Javascript escape?

Just from a browser developer console or Node.js repl, what's an easy way to transcribe a string as its unicode representation? For example I can input '\u0048\u0065\u006C\u006C\u006F' and the repl will show me 'Hello'
> '\u0048\u0065\u006C\u006C\u006F'
"Hello"
How can I reverse this?
> something('Hello')
"\u0048\u0065\u006C\u006C\u006F"
For example. I hope there are some convenient built-ins or browser console/repl support.

Regex Until But Not Including
(3 answers)
Closed 3 years ago.
I'm currently struggling with finding a way to extract domain names in urls.
My strings
xyz.weam.com
we2.wal.com
abc.workwork.google.net
I would like it to look for (com|org|net) and take the string before the match including the match until it hits the first (.) going backwards.
I have tried different combinations of lookbehind and positive lookahead but I was never able to make it stop at the right dot (.).
Thanks for the answers guys and especially to Aaron, his answer worked perfectly.
His Regex did the trick.
\.([^.]+).(?:com|net|org)$

I'm not sure what the code below means. I know how to use match, but I'm not sure on what the brackets and "^" signs mean. Is there a website to where I can understand what all you can do with match?
var imagesURL;
imagesURL = html.match(/CapImg[^"']*/g);
match is usually used along with RegExp to search through a data for a particular value or pattern of values. ..
You should rather go and read about JavaScript RegExp (or Regular Expression).

I want to find each youtube link in a page. I found on StackOverflow some regex i modified but when i have a html code with two youtube linq the result is one match like
youtube.com?v=videoid<div></div>youtube.com?v=videoid2
I want to get each youtube link only.
My regex is :
/(?:youtube\.com\/(?:[^\/]+\/.+\/|(?:v|e(?:mbed)?)\/|.*[?&]v=)|youtu\.be\/)([\w|-|_]{11})/
Can someone help me please?
Thanks and sorry for bad english.
try to add 'g' modifier at the end of the regular expression like so:
/(?:youtube\.com\/(?:[^\/]+\/.+\/|(?:v|e(?:mbed)?)\/|.*[?&]v=)|youtu\.be\/)([\w|-|_]{11})/g
That means globally (get all matches)

Regex for names

I'm creating a web store and I need to validate inputs with JavaScripts so the user doesn't have to submit a form to be given the PHP errors (although I'm also validating the form with PHP).
What I came up with is the following regex:
/^[a-zA-Z]+$/
But the above regex would only allow alpha characters whereas I also want to allow characters such as ' and - since obviously names may also contain these two characters. My question is, how to make a regex to allow alpha characaters AND the two characters above.
Besides that I also have one more question which just came in my mind, characters such as ă will pass the above validation ?
By adding them to your character group like so
/^[a-zA-Z'-]+$/
