Answer 1

Allowing Alphanumeric Characters (But Not 0)

If you wanted to allow for any number alphanumeric characters without minus symbols - , decimal points . or just zero as the string, you could use :

/^(?!0)[\da-zA-Z]+$/i

This will explicitly allow one or more alphanumeric characters, however it will not accept 0 explicitly. You can see an example of it here .

Allowing Only Numeric Characters (But Not 0)

If you wanted to only allow numbers but not 0, you could use :

/^(?!0)\d+$/i

You can see an example of this option here .

Answer 2

Sure!

document.getElementById(target).value = newVal.replace(/[^0-9]/g, "");

The above will remove everything except normal numbers, if you want to keep any special characters, add them to the expression.

Best of all its raw JS, just replace the selector with your current working value from this.

$(this).val();
