How to check whether a value is numeric or not in jQuery

Use the jQuery.isNumeric() method

You can use the jQuery $.isNumeric() method to check whether a value is numeric or a number.

The $.isNumeric() returns true only if the argument is of type number, or if it's of type string and it can be coerced into finite numbers, otherwise it returns false.

Let's take a look at the following example to understand how it basically works:

    // Return true (numeric)
    $.isNumeric(0xFF) /* Hexadecimal notation (0xFF represents the number 255) */
    $.isNumeric(1.25e2) /* Exponential notation (1.25e2 represents the number 125) */
    // Return false (non-numeric)
