testing= testing.match(/(\d{5})/g);
I'm reading a full html into variable. From the variable, want to grab out all numbers with the pattern of exactly 5 digits. No need to care of whether before/after this digit having other type of words. Just want to make sure whatever that is 5 digit numbers been grabbed out.
However, when I apply it, it not only pull out number with exactly 5 digit, number with more than 5 digits also retrieved...
I had tried putting ^
in front and $
behind, but it making result come out as null.
I am reading a text file and want to use regex below to pull out numbers with exactly 5 digit, ignoring alphabets.
Try this...
var str = 'f 34 545 323 12345 54321 123456',
matches = str.match(/\b\d{5}\b/g);
console.log(matches); // ["12345", "54321"]
The word boundary \b
is your friend here.
My regex will get a number like this 12345
, but not like a12345
. The other answers provide great regexes if you require the latter.
