The variable 'group name' should accept only 'A to Z, a to z, 0 to 9 and _'

[Archana23]

The variable 'group name' should accept only 'A to Z, a to z, 0 to 9 and _' using client script, I have tried below script but it is not working as expected.

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

var pattern = new RegExp('^[a-zA-Z0-9,_]*$');

var result = pattern.test(newValue);

if(!result ){

alert('Input is invaild');

g_form.setValue("group_name", '');

}

Hi @Archana23,

No need to use a client script for this:

You can use the OOTB Regex validation:
