how to extract words mixed with numbers regex

Question

I have a string containing a word that is sometimes mixed with numbers, I try to check if there is a particular word in this string, so I tried to do something like this: Original string:

str="123 here12K there34 bla"

regex:

RegExp(\'here'\d*+[A-Z]?).test(str)

and always get not available. I found this: similar question but still the same result

Did you try `str.match(/\w*\d\w*/g)`? Just the same regex from the post you linked to. If you need to add `here` before digits, just add it, `str.match(/\w*here\d\w*/g)` — Wiktor Stribiżew, Sep 06 '18 at 09:49
Notice you are escaping the first quote, and not the second one. Is that a typo? — kabanus, Sep 06 '18 at 09:49

var txt = "#div-name-1234-characteristic:561613213213";
var numb = txt.match(/\d/g);
numb = numb.join("");
alert (numb);

This might help you.

Edit 1

function hasNumber(myString) {
  return /\d/.test(myString);
}
console.log(hasNumber("123 here12K there34 bla"));

returns true if the string has numbers in it.

Your question is not really clear for a regexp question ...

But based on what you're saying :

/\bhere\d+?\b/g

will match any 'here' word that could have numbers after it
