如何提取与数字正则表达式混合的单词

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

Answer 1

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.

Answer 2

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
