in user event script how do you sanitize an email address?

<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/test|test> against a regular expression

netsuite uses the following pattern clientside, so its probably what you want serverside
```/^[-a-zA-Z0-9!#$%&amp;'*+/=?^_`{|}~]+(?:\.[-a-zA-Z0-9!#$%&amp;'*+/=?^_`{|}~]+)*@(?:[a-zA-Z0-9]+(?:-+[a-zA-Z0-9]+)*\.)+(?:xn--[-a-zA-Z0-9]+|[a-zA-Z]{2,16})$/i```


dont ask me how this particular regular expression works

That looks like 4 days worth of Perl development :wink:

its the kind of thing you go to stack overflow for

there are multiple versions of this regular expression, mostly because the more correct one looks even more ridiculous
