Need help with regexp

[blazb]

Why this doesn't work?

var f = this.getField("Text2").value;
var reg = /\+?\d+/;
var str = f.match(reg);
event.value = str;

I tested it in that site w3.schools.com and there it works, but in pdf it doesn't work.

You need to explain what you're trying to achieve...

I want to extract first number from "Text2".

Use this code:

var f = this.getField("Text2").value;
var reg = /\d+/;
var str = f.match(reg);
if (str!=null) event.value = str[0];
else event.value = "";

Thank you.
