I was wondering if anybody had a quick and dirty jquery method that will check if a value is numeric or not? I was thinking about using a regex type method to check the value, if not do not submit the form. I was using jquery validation, but I am running into issues just loading jquery validation.
I just have one value that I want to make sure is numeric.

The isNumeric() method in jQuery is used to determine whether the passed argument is a numeric value or not. The isNumeric() method returns a Boolean value. If the given argument is a numeric value, the method returns true; otherwise, it returns false. This method is helpful as it decreases the lines of code.
The $. isNumeric() method checks whether its argument represents a numeric value. If so, it returns true . Otherwise it returns false .
The jQuery $. isNumeric() method is used to check whether the entered number is numeric or not. $. isNumeric() method: It is used to check whether the given argument is a numeric value or not.
Sure, use jQuery's isNumeric() function.
$.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 If you love us?
