Hi Satheesh,

you want to restrict the below char.

Disallow following special characters (&

$

^

<

>

\

*

+

=

;

?

`

')

if yes then please check with script below.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if (isLoading || newValue === '') {

return;

}

var specialCharRegex = /[~@|$^<>\*+=;?`')[\]]/;

if(specialCharRegex.test(newValue)){

alert('special chars are not allowed');

g_form.setValue('<your field name where you are writing the special char>','');

}

I have tested it in my PDI and it's working fine.

Thanks,

Harshvardhan
