Regular Express Validation Help 2

[angiem]

I need to do a validation on a text box for the range from
A to F plus characters ()-*/+

This is what I have tried

function ValidFormula(obj){
var Formula = /^[a-fA-F][\-\(\)\*\/\+]$/
 if (Formula.test(obj)) {
  alert("VALID Formula");
 } else {
  alert("INVALID Formula");
 }
}

Thanks in advance.

Hi

You not provided enough information about the requirement. So only a guess :

var Formula = /^[a-f()*/+-]+$/i

I only want the users to enter A-F and ()-*/+ characters in a text box for example A-B or (A+B)-C.

Hi

So there will be one or more characters. Then my previous expression should work.

If "obj" is meant literally by the input element (the "text box"), then test its value.
>if (Formula.test(obj)) {
[tt]if (Formula.test(obj[red].value[/red])) {[/tt]
