How to check for numeric?

[Former Community Member]

I want to check if the data entered by the user is numeric or not. Below is my code:



if (this.rawValue != null) {

if(!(IsNumeric(this.rawValue)){

xfa.host.messageBox("Please enter Numeric ID");

xfa.host.setFocus(this.somExpression);

}

}



function IsNumeric(sText){

var ValidChars = "0123456789";

var IsNumber=true;

var Char;



for (i = 0; i < sText.length && IsNumber == true; i++){

Char = sText.charAt(i);

if (ValidChars.indexOf(Char) == -1)

{

IsNumber = false;

}

}

return IsNumber;

}



The above code is not working. Help is appreciated.

Standard JavaScript provides the isNaN() method to do this, so:



...

if (isNaN(this.rawValue)) {

...

}
