Is there a way to get a suitelet to POST without using the submit button? It's already in use by an existing process. I created a custom button, but the parameter string is going to be too long to pass to GET.

You need the behavior to function exactly as a submit button, where it sends a POST request and loads the Suitelet form in the same page?

Yep

I'm not sure about authentication for that

Custom "order items" page that generates POs. They want to add a request for quote process which reuses most of the logic.

I've built Suitelets with multiple buttons that all submitted the form. Your button click handler can select the form and call its submit() method.

Do you have an example? I'm not the strongest with client scripting. Looking at the dom elements and not sure where to begin. I think I've seen something like this in @mattdahse’s code before. Something like

NS.UI

to refer to the form?

There's probably only one

<form>

, so

document.forms[0]

would probably get it

(similar) For re-submitting the form after setting values I want to pick up on reload, I've done this before, not sure if it helps:

function refreshDetails(context){
        let cRec = currentRecord.get();
        cRec.setValue({fieldId:'records_selected',value:0,ignoreFieldChange:true});
        cRec.setValue({fieldId:'field_changed',value:"anything",ignoreFieldChange:true});
        //
        NS.form.setChanged(false);
        document.getElementsByName('main_form')[0].submit();
        return true;
    }

Note the NS.form line prevents NS complaining that you are leaving the page.

Oh if the

<form>

has a

name

attribute like @NElliott’s code indicates, then

document.forms['main_form']

would be more reliable

Thanks, all. I'll see what I can come up with after lunch

NS.form.setChanged(false);

Actual legend. I've been looking for a way of doing that

Thought I'd throw out 'too long for GET' is a bit ambiguous - you might be surprised how long that can be. Does anyone know if NS has a documented limit on querystring length in this case (received by a Suitelet)?

I couldn't find any official documentation. This random website claims to know. They either did some testing or that's just a guess. https://suiterep.com/2021/09/16/pass-parameters-to-url/#:~:text=A%20safe%20limit%20for%20URLs%20is%20roughly%20about%202%2C000%20characters.

I agree it’s longer than you probably think, but it’s measured in bytes, not kilobyes for sure.

It's a demand driven list on items, which are actually exploded because of a one to many relationship on "Vendor Lead Time" records. Too many lines to reasonably send in a query string. Pretty sure it's not succeeding rn

As an example, for Chromium based browsers - https://chromium.googlesource.com/chromium/src/+/master/docs/security/url_display_guidelines/url_display_guidelines.md#url-length 2MB urls are allowed.

submit was actually pretty straightforward. thanks @erictgrubaugh
