how toString() is used

sirou · ‎12-19-2022

hello everyone

I have a question about how toString() is used

var s = sys_email.sys_id;
var mm = s.subject.toString();
var reg = /\[[0-9]+\]/;
var result = (mm.match(reg) + "").match(/[0-9]+/)+ "";

Why can't this script extract the number from the email subject line?

@sirou You dont need to do GlideRecord on email table.

email object itself is gliderecord object.

var s = email.subject.toString();

The above line should give you subject. dont query email table

Replace line 3,4,5,6,7 with above line

Always try to use toString() or +"" when we GlideRecord any table and use sys_id.

EmailRec.sys_id.toString() / EmailRec.sys_id+""

You can also use getUniqueValue()

EmailRec.getUniqueValue().toString() / EmailRec.getUniqueValue()+""

Hi

the correct code is (assuming that sys_email is a variable holding a GlideRecord on table sys_email)

var mm = sys_email.getValue('sys_id');
var reg = /\[[0-9]+\]/;
var result = (mm.match(reg) + "").match(/[0-9]+/)+ "";
