parse a character out of a string in javascript

if i have a number of string like this

var info = "Information4Table"
var next = "Joe5Table"
var four = "ERweer11Table"
var nice = "ertertertn14Table"

and i want to parse out the number between the first word and the string "Table". So for the first item, i want to get "4" and in the last i would want to get "14". what would be the best way to do this javascript / jquery

1. You can use a regular expression to get the number from the string:

var n = /\d+/.exec(info)[0];

2. Another option would be to use regular expressions to take numbers out of the string:

var my_str="ERweer11Table";
var my_pattern=/\d+/g;
document.write(my_pattern.match(patt1));

This would output "11"

3. You can use a regular expression for just this sort of thing, especially handy/performant if the pattern doesn't change:

var regex = new RegExp(/[0-9]+/);   // or \d+ will also capture all digits
var matches = +regex.exec(yourStringHere);
var value = matches ? matches[0] : "";

Keep around the regex object and you can use it for all your processing needs. The matches variable will contain null if there's no number in the string, or an array with the matches if there was one or more. The value will have your number in it. The leading '+' operator ensures it's a number type instead of a string type.
