How can I select the next two characters in a string?

var one = "mb50 mt60";

How can I put the next two characters after a specific character into its own string?

For example: From the code above, I want the number 50 in its own string. I need it to look for the 'mb', then take the next two characters.

I can't use indexOf because the characters may be in a different place each time.

With a regex like that:

str.match(/mb(.{2})/)[1]

If there is more than one "next two characters" to capture, you should use replace:

var one= "mb50 mt60 mb20";
var results = [];
one.replace(/mb(.{2})/g, function() {
    results.push(arguments[1]);
});
console.log(results);

You can try doing it something like this

var string = "mb50 foo300",
    search = 'foo';

console.log(string.substr(string.indexOf(search) + search.length, 2));

or the regex way as Gael suggested.

You can use regular expressions, like:

var one = "mb50 mt60";
var regex = /mb(\d+)/g;
console.log(regex.exec(one)[1]); // => '50'
