"OR" in var selector

Question

I've trying to customise a script that normally triggers a GTM tag to populate a form's hidden field with a variable (session_url_campaign).

Here is the script:

<script>
(function () {
var value = “{{session_url_campaign}}” 
var selector = "input[name='859253_16342pi_859253_16342']" 
var field = document.querySelector(selector)
if(field){ field.value = value||"(none)"; }
})();
</script>

I'd like to use this tag to populate all my forms, but unformatunately, my CRM - Pardot - uses form specific names when a same field is use across different form. The name of my hidden field in the above script is 859253_16342pi_859253_16342, but it could be 859253_16342pi_859253_16343 in another form.

Is there a way to use a "OR" logic for my name?

After some research I've found some mention of ||. Would solving my problem as easy as adding between the different values, as below?

<script>
(function () {
var value = “{{session_url_campaign}}” 
var selector = "input[name='859253_16342pi_859253_16342||859253_16342pi_859253_16343']" 
var field = document.querySelector(selector)
if(field){ field.value = value||"(none)"; }
})();
</script>
