javascript regexp help selecting a word but no the first character

Question

I am using javascript, and I am trying to work out how to select all characters of a word but no the first character.

For this, I am using regExpr. So the following expresion:

/\\B[a-zA-Z'-]+/gi

should select all characters except the first one of each word, but it doesn't work for the text: "I'm a little tea pot" because of the apostrophe. I have tried everything, but dont know what else. I would apreciate any suggestion or support in this.

Thank you in advance!

Answer 1

Try it here (Choose JS, PHP is default tab): http://regex.larsolavtorvik.com/

As simple as:

string.match(/\B\w+/gi);

Answer 2

A matching regular expression pattern is as follows:

 /\\b\\S(\\S+)/gi 

See the demo here .

Answer 3

Consider the following approach using String.split and Array.slice functions:

var str = "I'm a little tea pot", words = [];

str.split(" ").forEach((w) => w.length > 1 && words.push(w.slice(1)));

console.log(words);  // ["'m", "ittle", "ea", "ot"]

Or by using RegExp.exec function with regexp /\\b\\w([\\w'-]+)\\b/g :

var str = "I'm a little tea pot", words = "", res, re = /\b\w([\w'-]+)\b/g;

while ((res = re.exec(str)) != null){
    words += " " + res[1];
}

console.log(words);  // "'m ittle ea ot"

Answer 4

s = "I'm a little tea pot, let's pour me out";
re = /(\B|')[a-z-']+/gi;
lastLettersArray = s.match(re);
console.log(lastLettersArray);

output

["'m", "ittle", "ea", "ot", "et's", "our", "e", "ut"]

Edit, Updated

You can use String.prototype.split() with RegExp /^.{1}|\\s[a-z'-](?!=\\s){1}|\\s/ to exclude first character in word, match remainder of word; for loop, String.prototype.replace() to replace matched words returned by .split() following calling .toLowerCase() on matched word.

 var str = "I'M a liTtLe tEa pOt"; console.log("original string:", str); var res = str.split(/^.{1}|\\s[a-z'-](?!\\s)|\\s/) .filter(Boolean); // `["'m", "ittle", "ea", "ot"]` for (var i = 0; i < res.length; i++) { str = str.replace(res[i], res[i].toLowerCase()) }; console.log("res array:", res, "replaced string:", str);

You can use String.prototype.slice() with parameter 1 to return string excluding first character in str

 console.log("I'm a little tea pot".slice(1)) 

or String.prototype.split() and Array.prototype.slice() to return array excluding first character in str

 console.log("I'm a little tea pot".split("").slice(1))
