Hi sam, Use jQuery.isNumeric( value ) as: var str = "Hello world!";
var res = $(str).substr(1, 4);
$.isNumeric("-10"); // true
$.isNumeric(16);// true
$.isNumeric(0xFF);// true
$.isNumeric("0xFF"); // true
$.isNumeric("8e5"); // true (exponential notation string)
$.isNumeric(3.1415);// true
$.isNumeric(+10);// true
$.isNumeric(0144);// true (octal integer literal)
$.isNumeric(""); // false
$.isNumeric({});// false (empty object)
$.isNumeric(NaN);// false
$.isNumeric(null); // false
$.isNumeric(true); // false
$.isNumeric(Infinity);// false
$.isNumeric(undefined);// false
