check numeric in jquery

To check if a value is numeric in jQuery, you can use the $.isNumeric() function.

Here's an example:

var value = "123";

if ($.isNumeric(value)) {
  console.log("Value is numeric");
} else {
  console.log("Value is not numeric");
}

This will output "Value is numeric" in the console.

If you pass a non-numeric value, such as "abc", the function will return false.
