How to remove character from fixed String

Question

I have a value like

V = "Val1,Val2;Val3"

In this case If I need to separate "Val1,Val2" from V I am using this

var newVal = V.substr(0, V.indexOf(";"));

But this case is faling for some value like this

V = "Val4;Val1,Val2;Val3"

Any idea how to take only the value which having "," and remove all other character which is separated by ";"

What exactly is the logic? Anything that matches the regex \w+,\w+…? (hint hint) — deceze

What is this "value"? What is it supposed to represent? Why do you deal with multidimensional data in a string seperated by ; and ,? Or are you trying to parse it? — Thomas

use the regex

\w+,\w+

to solve this

function match(str){
    return str.match(/\w+,\w+/g);
}

console.log(match('a;b,c;d'));
console.log(match('a,b;c'));

This is working for small values but if not long values. I am trying this. "bayern munich germany;wayne rooney, manchester united; messi plays barcelona"

Use \w+(?=,) regex to get all those values

you mean `var newVal = V.match(\w+(?=,))

V.match(/\w+(?=,)/g)
